Upa, the man holding the arrow, tightened his grip around his sacred weapon as he saw the two men coming near him and his mate, Luna. The two looked a bit different. One wore normal clothes – a black cargo, black tee and a blue jacket. His hair was bluish white and he had a sword hung on his back and from the sheath Upa could tell that the sword was no ordinary sword. Also, this young man's power level amazed Upa. He had felt this kind of power in Goku, Vegeta and Piccolo, who was a bit more powerful than them both.

Then there was the other man. He wore a red and yellow metal suit and seemed to be walking pretty casually wearing it as Upa could feel that the man inside the suit was an ordinary man.

Upa felt a hand on his shoulder and knew it was his wife. Being a fierce warrior and the keeper of the Lookout's secret, Upa knew his surroundings. The two men, especially the one with the sword had a body language that clearly said they weren't here to cause trouble. Upa only thought that this sword carrying man knew what he was doing. As for the metal man, Upa wasn't clearly sure.

"You see those two?" Trunks asked Tony.

"Yeah?" Tony said.

"That man's arrow is sacred and can easily pierce through your armoured suit. The poison at the tip of the arrow will kill you in an instant. So don't act like anything that will make them see you as a threat. Can you do that?" Trunks asked.

"I think I can," Tony said, surprised at the revelation. He had already asked Jarvis to run some scans on the type of poison Trunks had just mentioned but Jarvis couldn't. it only meant that whatever the poison this ancient looking man had at the tip of his arrow was surely deadly as by the way Trunks spoke of him, Tony thought that this boy might be knowing about those two.

Trunks raised both his hands in a surrender position and gestured Tony to do the same. The iron warrior also raised his hands. The two saw as the armed man raised his bow and arrow at them as the two got nearer.

"Who are you?" Upa asked.

"We are here to seek permission to go to the lookout," Trunks said.

Tony thought what this lookout was but whatever it was, it had clearly got the armed man and his mate's attention.

"I don't know what you are talking about," Upa said, trying to make this young lad realise that he had mistakenly heard the name of the most sacred place on earth.

"I have come from very far," Trunks said. "I have come with a warning and I want the Guardian Dende to know about it so he can alert the Z warriors."

This led Upa and Luna by surprise. Not only did this boy knew about the Z warriors, he also knew about the Guardian, not to mention his name!

"I know you have the ability to know a person's history and character," Trunks said, "And I can let you see my nature and past if that suffice you to grant us permission to go to the lookout."

And with that Trunks unhooked his sword belt and placed the weapon on the ground. He then gestured Tony to do the same and the iron warrior released himself from his suit and came out.

Upa could see that this young man was heavily injured and was hardly in any position to pose a challenge for him in case he decided to have a fight. The other man, the one who had this metal suit, was as strong as a normal human with only a bit higher ki which Upa guessed the man would've gained through martial arts as he could clearly see it in the way this man walked.

Sensing the young man was telling the truth as the other guy only followed his lead, Upa lowered his weapon, he felt Luna's grip tighten a little on his shoulder.

Seeing the man's gesture to come forward, Trunks picked up his sword and hung it around his back and slowly walked towards the tribal couple. Tony followed his lead, leaving his suit behind. He knew he could call it whenever he needed it.

"Kneel," Upa said in a firm voice, showing the two men that he still had doubts over them. Trunks knew this from the stories and kneeled down. Tony, a bit amused by this all remained standing but them he earned a glare from Upa, Luna and even Trunks.

"Yeah, okay," Tony said and quickly kneeled down.

Trunks stumbled a bit as his broken knees now had his whole body weight but he had to earn the trust of these two or else his coming here will go in vein. He felt a rough hand on his head and quickly his vision blurred as images of his life until now flashed before his eyes. He felt like his head will explode as he was reliving those nightmarish days and nights. How he ran away from the threat known as Cell. How he witnessed the one and only kill of that monster through his own eyes when that beast killed his master and best friend Gohan. Then he saw the events after that. How he evaded that monster whenever he would come out, looking for any surviving people to get them to the shelter his mother and grandpa had built. Then further images were flashed until he sat in the time machine with this four people and came here – back in the past.

Tony had the similar type of feeling but the memory he was reliving was way too different than that of Trunks. He saw the first time he and his fellow avengers had seen Cell. The monster had arrived out of nowhere and in one single blast, wiped out entire Manhattan Island. It was as if the place had suffered an attack of several atom bombs. SHIELD had then sent in their best warriors, their second best actually as the avengers were no longer working under SHIELD but with them and were only called when the situation was really, really bad.

Tony saw through the memories how he had witnessed that monster taking out every single superhero effortlessly. They had all died and only then had Fury called his team – the avengers. Some new recruits, who weren't new anymore, prepared themselves as they already knew what this threat was capable of. Only their knowledge of this threat's capability of destruction was way too small. Tony and Steve had executed a plan. They Vision was the strongest in their team, followed by Thor and Banner who were more or less, equal in their strength provided Banner didn't get super angry. So those three were reserved as the avengers' last resort and the three had wholeheartedly agreed but then when the team had arrived at the battlefield, they didn't even get a second's chance as a huge explosion shook their jet hard, crashing it in the river. The impact of the crash had taken out Clint completely. His body wasn't able to take it as after the events of Ultron, he had resigned from being an avenger and had slacked down, giving more importance and attention to his family. It couldn't be blamed. Clint knew he wasn't going to pose a challenge to the new threats which everyone knew earth was impending upon.

Romanoff was next. Her loss had enraged Banner quicker than it had been planned as he turned into his angriest form, running towards the monster with the only attack he was known for – beat the guy into a pulp.

But as a shocking revelation, the green bug type monster had stopped Banner with a mere finger. He then tipped it, throwing Banner at least a mile away, crashing him through the ruins of the buildings. This mere demonstration had shown the last remaining heroes of the earth that they were facing an enemy unlike any other they had ever faced before.

"We need a contingency plan," Rogers had said but like most of the time, this time as well, it wasn't going to bring out much favourable outcome.

"We can't stand against him," Tony saw himself telling his teammates. "He tossed Banner like he was made of paper while we all know that that attack of Banner's was enough challenging to even Thor. This guy wiped out an entire island full of people without breaking a sweat! I saw we retreat now and come back later when we are a bit more prepared."

"You talking about running away?" Rogers said.

"Like we have another plan!" Tony had said, rolling his eyes at Rogers' military grade antics. That seventy year old guy was really annoying most of the times, if not every time.

"Keep talking to yourself that then," Rogers had said and then he ordered Vision to attack the new enemy. The pink coloured avenger, the most powerful among them all gave Rogers a nod before using the crystal's powers, creating an energy blast unlike anything he had done before. But like the rest of his team, Vision, too, didn't know the true extent of this new enemy. He was still new to all of this. He was still undergoing his training, sharpening his skills to prove a better challenge in a battle.

The yellowish beam that emerged from Vision's crystal at his forehead, connected itself to the green bug but it was like that that monster was still unaffected by it. Tony knew what the outcome was going to be and he prepared every single weapon his suit had, which included a small AA battery sized three mega ton nuclear bomb – his type of last resort.

His suit made the mechanical voice as every weapon outlet was opened up by Jarvis. The new and improved suit Tony had made was unlike any other suit he had made before. The alloy he had managed to make fusing adamantium and vibranium, he had used it to make an almost indestructible suit which could even bear Thor's hammer, if he could exclude himself being thrown away from the attack. But the suit was tough enough to easily handle the hammer's tackle.

A bright light had happened as his team saw Vision been engulfed by a yellowish beam from the monster. The beam had enveloped Vision completely and once it was cleared, there was no sign of Vision. Jarvis, having his vision inside Vision, could sense his energy signals but not anymore and he had already informed Tony about it. Not wasting any more tine, Tony took off, but not towards the monster, but at the falling crystal that was somehow saved from the attack although it had some cracks formed on it. Thor knew more about it and he could say whether or not this stone could be harnessed or not.

Catching it mid air, Tony warned Thor to take Rogers and leave. Sensing the seriousness in Tony's voice, Thor took a hold of Rogers and before the captain could understand anything, the thunderer had already started to rotate his hammer and a moment later the two were flying away from the place.

Tony took off on the opposite direction and fired off every single weapon his suit had, along with the nuclear one. He was sure he was far enough to be saved from the shockwave which shook the entire deserted city, engulfing it and the dark sky above it in a cloud of mushroom shaped smoke. But the next moment he saw the monster facing him. This made no sense as he had made the suit take off at supersonic speed. How could this monster overtake him? That, and not to mention he had not even a scratch that the possible blast could have caused! Just what was this thing?

"You cannot leave this early," the monster said in a surprisingly human voice and raised his hand, the next moment connecting it with Tony's suit, creating a hole where his hand had connected, and disabling Jarvis. Fortunately, the suit's flying mechanism was still in Tony's control, making it possible for him not to fall. But he knew this was going to be over soon, until a flash of light happened, taking them both off guard and the next moment the runic hammer connected with the face of the monster, sending it away. From the lightning, Thor had emerged but before Tony could do or think anything, the thunderer had caught his hand and was gone.

The monster could not sense the ki of a thunder god of Asgard.

Upa removed his hands from the heads of the two new comers. His eyes were wide with shock and surprise. He didn't know what to say. He had also sensed their nature of character while he read their minds and knew they were of pure soul. Then his eyes turned to see the young boy who was somehow remaining conscious.

"Bring me a senzu bean, now!" Upa said and Luna, not questioning anything, ran inside their tent and brought out a small pouch. Tony saw they took out a small pea sized bean from it and put it in Trunks' mouth. The young man, probably knowing what it was, started chewing it quickly and a second after he had swallowed it, his body bulked up before going back to normal. Tony's eyes widened with surprise and shock as he saw Trunks' wounds heal up, though not completely, but enough for the man to stand and run a marathon.

"What was that?" Tony asked, turning towards the man who was looking down at them both with curious eyes.

"I grant you two the permission to go and see the Guardian," Upa said. "I have informed him of your arrival and he is expecting you both. Now, go."

Trunks stood up, followed by Tony who was now wondering where the hell the two of them will go now when he saw Trunks turn towards his right and look upwards. Tony followed his gaze and his surprise knew no bounds as he saw a round pillar heading towards the sky, to infinite heights. The pillar had ancient symbols engraved on it which Jarvis failed to interpret. He walked to where Trunks was standing, looking up at the sky. He wanted to ask the boy several questions but saw the boy had his eyes closed, like he was in deep thinking – or was he praying?

Trunks opened his eyes. "Leave your suit here. We will get it once we return," he said.

"Then how will we go there at the top which I suppose is where we are going as I can see no other place else to go?" Tony asked.

"Leave that all to me," Trunks said with a smile. "These two will take care of your suit. I trust them with my life."

Tony looked at Trunks for a minute before taking out a small earpiece from his pocket and fitting it in his ear, connecting to Jarvis. This way he could call his suit whenever and wherever he was.

"Alright, I am ready," Tony said and a moment later he felt Trunks' hand snake around his waist. "Um, what are you doing, boy?" he asked.

"Making sure you don't fall down," Trunks said. "Oh, and I think it would be better if you had your suit's helmet because I don't think your fragile eyes would be able to take up all the force of air."

"Alright," Tony said, shrugging his shoulders. "Got to do what's being told." He pressed his ear piece and mumbled something which sounded like 'Jarvis, bring me my visor.' Suddenly the metal suit rumbled as the visor's eyes lit up a navy blue and came out of the entire body arrangement and flew towards Tony, opening through various places and placing them at his head frame.

Trunks, Luna and Upa watched the whole thing happen with amused eyes. To be honest, a man in his mid forties, wearing tee and jeans with a metal helmet cum visor with glowing eyes on his head with red and yellow colour looked pretty weird.

"Ready?" Trunks asked.

"Ready," came a bit robotical voice of Tony, who again felt Trunks' hand snake around his waist. "Remind me why I can't go on my own, wearing my complete suit?"

"Because only I have been granted to go up there," Trunks said.

"Alright, let me get this straight," Tony said. "Those two allowed us to see this...this pillar sort of ancient...well...pillar which was invisible to us before. I thought that was supposed to let us go where the pillar went, if that's where you are planning to go?"

"You will reach the place," Trunks said, "but you will not be allowed on it on your own. You need to have someone with you. And that someone is me because there is someone very important to me in this timeline. Now, let's go. I don't want to make the Guardian wait."

And with that, Tony felt Trunks' grip around his waist tighten a little bit before he took off at blinding speed. Tony was shocked. This boy was FLYING! But his shock was yet to come when he heard a loud boom. The boy had just gone past the speed of sound.

"Jarvis, help me calculate his speed?" Tony asked his faithful friend.

The virtual numbers displayed in front of his eyes and Tony gasped in surprise. The data showed Trunks was flying three times faster than the speed of sound.

"Well, looks like we are going to encounter something interesting here," Tony said when Jarvis notified him that they had entered the exosphere and activated his in built oxygen tank which Tony had also installed inside his visor for 'just in case' scenarios. But a look at Trunks made the man in the visor realise that he was breathing normally. "Jarvis, check the atmospheric oxygen level," Tony asked.

"Sir, the level is at two percent," Jarvis said.

"Then how come Trunks is not fainting?" Tony said to himself when he was shown another data within his visor.

"Sir, there appears to be an invisible field around the pillar," Jarvis said. "The oxygen is normal within this shield, unlike on the outside."

"Can you make out the energy signatures?" Tony asked.

"I am sorry, sir," Jarvis said. "The field energy is unlike anything I have ever seen."

Tony huffed but then he saw something coming right at them, or rather they were going right at it. Jarvis zoomed up the image for Tony to see it better and he saw they were heading towards a small dome shaped thing standing at the top of the pillar. But then a minute later Trunks flew right past it. Tony swore he had seen a white fluffy cat with a cane along with a small, fat man with long hair and a samurai sword.

Tony also saw that the pillar was now gone and instead a very thin, red streak was what Trunks followed until soon enough, he saw a huge round thing floating right above him. it looked very ancient and...Weird.

Trunks stopped reaching at top of it, recognising the place after such a long time. He remembered training up on here, in the time chamber when his mother was killed by Cell. Then he saw two people standing there, looking right at him. he knew, since his timeline was different, he had Kami as their Guardian but in this timeline, they had Dende as their guardian. The Namekian child was still the same height as he was on Namek when Goku had fought Frieza. Beside the small Guardian stood his assistant and friend Popo. The round shaped man with pitch black skin with an Arabian style of fashion still was a puzzled thing for Trunks. He had been told that this assistant, Popo, he was very powerful but he never actually showed it. He knew he couldn't feel Popo's ki, just like Dende now as they both were deities. And one couldn't feel the ki of a deity.

Dende had heard from Upa that there will be two men going up to visit him. And that these two had travelled back in time along with three others to warn the Z Warriors of an impending threat which had wiped them all in the future. Those words had worried Dende too much. he was already considering not being earth's Guardian but under Piccolo's/Nail's persuasion, he had accepted. Also, Gohan and Krillin had told him they would help him get used to it as they knew from Kami what it actually felt to be a Guardian. To make him feel more relaxed, the Kami, inside Piccolo, had given Dende his share of memories and experiences when he was the Guardian. All that had really helped Dende but now, hearing about this time travel and that all the Z Warriors had been killed and all really made him nervous.

Tony was baffled looking at the place. It was enormous. As huge as the hellicarrier SHIELD used to have. He could also see a small green man who wouldn't be more than three feet tall. Beside him was a round man wearing Arabian fashioned clothes. He felt Trunks taking him and descending down on the tiled floating place which had a castle. The place was beautiful and was cleaner. It looked more like a holy place or something but being an atheist, Tony soon shoved those thoughts aside.

The two landed on the lookout. Trunks remembered this place. it never changed except now in his timeline it didn't exist anymore.

"Are you Dende?" Trunks asked.

"I am," Trunks said. "And I suppose you are the time traveller. Well, let us hear what you have to say."

00000

Rogers, Banner and Thor were waiting where they had landed through the time machine. Rogers was still pissed off at Tony for trusting a stranger who claimed to have brought them all back in time. Although looking the place around himself, he could see there was no damage done as that monster had literally destroyed everything.

"How long do you think they will take?" Banner asked.

"I don't know," Thor said. "And what is this time travel? I never thought travelling time would ever be possible. Are we really back in time?"

"The same question's been eating me since we got here," Rogers said in an annoyed tone. Banner rolled his eyes.

"Seriously Steve," Banner said, "learn to be patient."

"And why would I be?" Rogers said. "That kid appears out of nowhere, takes us all inside a ship and then claims to have brought us all back in time. I don't believe at it at all!"

Banner knew it was pointless to argue with Steve at the moment as the avenger was pissed off at Tony for not listening to him.

It had been more than three hours when suddenly Bruce and Thor saw something in the sky coming right at them. Rogers was facing the other side so he didn't see it coming. The two avengers' eyes widened when they saw Tony and Trunks land in front of them. The surprise wasn't to see them both but Trunks. None of them knew Trunks could fly.

Rogers turned and saw Tony and Trunks' arrival. "So?" he said in a bossy tone like he always said, "Find anything?"

"Actually yes," Tony said. "Though I suppose I won't be the person worthy of telling you guys about it. Trunks?"

The seventeen year old demi saiyan now had the three avengers' eyes on himself. He always got nervous whenever he was the centre of any sort of attention.

"Alright, I'll tell," Tony said, seeing Trunks was taking too long to speak. "We went to the Guardian of earth. Do you guys remember the floating place my scanner had found?" the three avengers nodded. "Well, turns out, it was the place of earth's Guardian destroyed by that...Cell?" Trunks nodded. "Cell," Tony said.

"What Guardian?" Thor asked, suddenly taking an interest in the topic.

"Well, apparently the earth has a Guardian," Tony said, "or in simple words a god. He resides at the top of the planet, hidden to everyone's eyes unless granted special permission, something which we got, thanks to Trunks. He sees everything going on over the planet."

"So you are saying you both went to meet a god?" Rogers said. "This is getting more and more ridiculous!"

"So...did you find anything?" Banner asked, ignoring Rogers' comment who now clearly showed no interest in the talk anymore.

"We did," Trunks said. "We told the Guardian of who we are and where we came from. We also told him about the threat and he is currently looking around the planet using his Guardian powers to find it. We will soon be informed and so will my brotherhood."

"Speaking of the Guardian," Thor said, "you said he watches over the planet, right?" Trunks nodded. "Well, if you all must know Asgard also has a Guardian."

"Every planet which supports life has a Guardian," Trunks said. "On our planet, people have titled him as god. Though he isn't a god actually but seeing the power he's been granted, you could call him one."

"So why not tell this guy to find this Cell and finish him off?" Rogers said.

"Because he isn't that powerful," Trunks said. "I know from my fighting experiences that Thor is a god because I can't feel his ki...energy. The same goes with Dende, the Guardian of earth. They are not fighters."

"He's right," Thor said. "Guardians have to be more of a pure nature and soul than be stronger because being pure weighs more than being stronger. Asgard also has the same principle."

"I have one question, though," Banner spoke. "Trunks, how can you fly?"

"I manipulate my ki to push myself upwards," Trunks said like it was a no big deal but then he remembered these were normal humans more or less.

"Come again?" Tony asked. Even he was interested to know how this young boy could surpass the speed of sound.

"Well, I don't know how to explain this. I've never been in this situation before," Trunks said, trying hard to find a way to explain them a way of how he can fly. "Well, you all know what a ki is, right? It's the energy one has inside of him. All I do is project it out in the practical world. You can do it too but for that you first need to learn to calm your mind and body and create a connection between them so they work together and independently whenever required. It usually takes time but if you are familiar of it then you can easily learn it."

Trunks could see that the four avengers hardly understood what he said so he decided to change the topic.

"What's with that hammer, Thor?" Trunks asked. "Why are you always carrying that? It looks weird."

"Speak with respect, kid," Thor said in a bit threatening tone. "This is no ordinary hammer. It is the greatest weapon of my planet, my world and my people..."

"What he means to say is that he really loves his hammer and that no one else is worthy enough to hold it," Tony said.

"Although there was one. His name was Vision," Banner said.

Trunks listened with interest as he looked at the hammer in Thor's hand. It really looked weird to begin with. He saw the hammer had strange symbols on it and looked to be made of some heavy and high density metal. But his saiyan side was coming out.

"Mind if I try and lift it?" Trunks said, surprising everyone.

Thor gave out a low chuckle as he saw the young boy in front of him. "Are you sure kid?" Trunks looked confidant so Thor gave in. "Fine. But don't complain when you can't lift it."

"Note. Trunks if you lift it up, you will then rule Asgard," Tony said.

"We will see about that later. First I need to see if what you guys speak of this hammer is really true or not," Trunks said.

Thor smiled and kept the hammer on the ground. He then gestured Trunks to lift it up. The demi saiyan first looked confused. Thor could simply have thrown it towards him. At least this would've spared him from bending. Although Dende had healed him completely. He, however, walked near to the hammer. The four avengers looked interestingly at the boy. They all knew with confidence that this boy would not be able to lift up the hammer. But what happened next shocked them to no end as Trunks gripped the hammer and picked it up like it was some ordinary hammer.

Thor was baffled, seeing his hammer being lift up by a mere mortal human. Not to mention a seventeen year old child! He had seen Vision lift up his hammer but that was out of desperation and he had to struggle a lot. It was a life and death situation and Vision had used the power of the crystal which indeed had more power than Thor's hammer. But this boy had effortlessly lifted up the legendary hammer without breaking a sweat.

"Hey, that wasn't so hard," Trunks said as he turned the hammer around on his hand, examining it more closely. "It's just like any other hammer, only bigger and of a bit weird shape."

Thor was out of words and so were Banner and Rogers. Tony, however, wasn't as he had recently seen a Guardian and a place as big as the hellicarrier floating in the exosphere. He had seen this kid flying at speed higher than that of sound and could clearly now say that Trunks could go even faster.

Bottom line – Tony was hardly surprised seeing Trunks lifting up the hammer with ease.

Trunks gave the hammer to a now surprised Thor who took it from his hands.

"Come on. We now need to go to Mount Paozou," Trunks said.

"What's in Mount Paozou?" Rogers asked, coming out of the shock that this boy could lift Thor's hammer with ease.

"That's where the leader of our brotherhood lives," Trunks said.

"Who?" Banner asked.

"Son Goku."
