Ultrman Zero x mass effect

Commander Shepard has seen a lot thing in his life all around the galaxy. A giant man eating worms, blue skin aliens who turned to be mongered species, floating jellyfish, and robot zombies. But what truly shocked him to the core was seeing the citadel hub of the galaxy under attack by a giant 10 storage height monster that has three heads like a dog (Galberos).

The giant monster was rampaging one of the wards the Zakera wards to be exactly. Its giant claws tear down the tallest sky scrapper on the citadel like tower cards. More surprise one of its head can make a massive fireball burning anything in its path.

"Anderson, are you seeing this?"

"I'm seeing Shepard, having trouble believe it."

"Commander I think Godzilla went on a rampage in space." Joker tries to lighten the mood.

"We can see that Joker but how a monster that size manages to land in citadel space without anyone noticing?"

Flashback

The citadel space was quiet going on their unusual routine as many ships from different species come and go. The council pride and joy destiny accession can be seen hovering around the citadel the giant dreadnought standing guard like a loyal dog.

Matriarch Liady the admiral of the dreadnought looking around "Is there anything to report."

"Nothing madam everything is going smoothly."

"That's good," The admiral just sighs how boring it was. Sure being command one of Asari greatest pride was a great honour but she feel bored nothing to do.

Until one of the operators shouted. "MA'AM something coming towards the citadel, it's big and fast."

"What is it?"

"It's a meteor and heading straight to the Citadel."

"Huh nothing unusual" The citadel once had a meteor and asteroid collision once ready to ram the citadel but like always the destiny accession would obliterate it like the rest.

"Prepared to fire the massive mass accelerator canon, target the rock."

The operators calculate the shoot. "It ready to fire ma'am."

"Fire!" the matriarch shouted as the crew witnessing the massive round flew towards the meteor. She just smile it was something to relived her boredom for once. But something unexpected happen the round made contact with the meteor just disperses.

"Negative impact ma'am"

"What impossible fire again." another round was fired but the outcome was the same. She felt fear and called the entire vessels to help with the destruction of the meteor. At the same time announce an emergency that the wards must be closed immediately.

The fleet arrive compose of different species fired at the meteor out to protect the citadel. Like the Titans from Greek mythology flatten the earth it was impossible. The meteor continues speeding towards the dreadnought ready to crash it.

"Evasive maneuver!" the matriarch quickly commands the vessel to avoid the collision while other ships that couldn't escape are caught by its ramming power.

It then crashed on the Zakera ward it was thanks to the ingenuity of the citadel that the wards didn't break. However when the citizen think it was over they were wrong. A sound like beast was heard as the flames from the meteor it appear a face that in the middle with sharp teeth and on its side two dogs heads. Its height was 50 meters.

The citizen whom saw the monster started to scream and run for their lives while the beast went on a rampage. C-sec and the military were mobilized to contain the situation. The council wouldn't have believed if they haven't seen the giant monster on a rampage. It wasn't just that simulates attack had being happen on other planets.

Illium (Red King)

Digeris (Gan-Q)

Jamone (Bemstar)

Bekenstein (Sadola)

This was no random monster attack this was an invasion. You don't need an army to wipe an entire species not when you have giant monster destroying everything on their path. The distress called was all over the Normandy it was a nightmare. Not even Anderson knew what to do he doubt calling the alliance fleet would do anything.

"What should we do Anderson?"

"I don't know Shepard."

"Kaiden prepared the shuttles I'm going in down there."

"That's suicide Shepard."

"No Surviving against a thresher maw that's suicide Anderson, I must go my little brother is over there and I'm worried even though his location at the embassy."

Anderson understands and he can't stop him. "Do what you must."

"Thank you, Kaiden, Ashley preps the Mako."

The Zakera ward was in chaos the sound of explosionn building crumble and people running from their lives from the giant monster. They all felt fear for the first time thinking that no monster would ever attack the citadel it was just impossible and the safest place in the galaxy. While everyone was running Wrex the battle master was looking at the monster with interest. Unlike the giant worms on Tuchanka that so called monsters was more intimidating and his gene Krogan was screaming to fight even if the odds were Zero. "It seems the galaxy just became more interesting."

Garrus Vakarian and the C-sec were firing their weapons at the monster they even bring a tank. It only piss it off even more as it stomped the tank with its giant feet crushing it. "I should have stayed home today."

Tali'Zorah nar Rayya a Quarian on a pilgrimage was running hiding from the giant monster sight, the reason why she was in the Citadel was to hide from Saren that knew about the Geth. But things turns for the worst when she wanted to hire protection the giant monster came and killed Fist. So she went hiding.

The council can look in utter disbelieve seeing a giant monster rampaging through the citadel they have so many mix feelings of this. Sparatus think it as a challenge to the Turian military might that they can beat the monster. Tevos would try to communicate with the beast or try something to avoid any destruction. Valern would want to study such specimen if the creature is indigenous to the galaxy.

Galberos thrash the sky scrapper on the wards like paper tissue as it tumble down to the ground while the other parts flew to space floating. It was chaos on the Citadel, it reminds the time during the Rachi wars and Krogan rebellion, citizen running to escape the monster and military trying to destroyed it. Shepard was on the station battling the menace even he knows that he be out match, it's better to do something than nothing especially keeping his brother safe.

It was then the pilot Joker shouted at the commander "Commander we got something and it's fast. It's heading straight towards the citadel."

"What is it another monster!"

"I don't know whatever it is it's faster than any FTL and it looks like a ball of light." Before Shepard could ask more the ball of light arrive with a loud thud.

The appearance was humanoid with a mixture of red and blue color. Its chest on the centre was a blue jewel. The head had two horns with yellow glowing eyes. Its height was similar to the monster that was rampage the citadel.

Galberos look at whom the giant and recognize it the Ultra Force the one called Zero that one that defeated his kind. Galberos roar "groah" as he ran straight towards Zero. Zero was prepared he stood his ground and stopped Galberos charge. Then he jump and punch its middle head. The beast stumbles a bit. Zero continues the attack as he jumps kick the other two heads. The monster fire it's fireball at Zero who just punch the balls like snowballs disperse in instant.

While Zero was battle his foe. Everyone on the citadel was looking at the battle in tense seeing another Titan fighting a giant monster. Some think its hope other fear it might be another monster that was just fighting for territory.

They were others telling to shoot the Titan humanoid monster especially the Turian while the Salarian using their quick thinking letting them killed each first. The Asari think if they can communicate with the blue and red giant.

Galberos had enough when he spotted innocent civilian was near he fired his fireball towards them. Zero quickly jump and protect them with his body. Galberos growl in triumph and continue its barrage.

The civilians were awe seeing the Titan protecting them including others. "Don't just stand there help him." Shepard shouted seeing the Titan was their ally. Their effort was fruitless as the monster just ignores them until someone brought the big guns and fired one of its head. It stops the barrage and screams in pain.

"You military buffoon forgot that, that Titan kick one its head its weak point." The Krogan battle master had walk toward Shepard. "Hey you fired at the other head if you are a good sniper."

Garruss Vakarian one of C-sec best sniper quickly took aim at the other head and fired a rocket at it. The beast felt pain from both of its head. This gave a chance as Zero brandished his blade from his head. He quickly ran towards Galberos and sliced it.

Everything was quiet the monster then separated into two horizontal and exploded. Everyone cheer with joy the destruction of the monster menace but they were other planets that need to be saved. Zero summons his Armor to become ultimate Zero and quickly flew towards Ilium.

With threat over the Normandy and other ships were able to land on the Citadel except it was different scene . Wreckage of ships, tank and building can be seen at the Zakera ward. The other wards were luckily since it was rampaging on one they dreaded what would happen if the monster decided to jump on another wards.

While the citadel was doing damage control, the council found out that the Titan appears on Illiun, Tevos quickly told their military to leave it alone and that it was their ally. After Zero finishes his job on the planet he went to the next one and continues until its finish them all.

The council was stumped it a threat they never faced before and thinking what to do in this situation. It was a thought to select the human a spectre but they are needed military leaders and information. They fear this wasn't the last one.

It also brings question of the giant humanoid that was protecting the civilian thinking it might an ally that would enlighten them of this attack.

At the same time an Asari whom was on the Citadel hiding from others in the shadow was confront by alien bat Gurashie.

"You didn't say that there was another Titan."

"It's miscalculated but his just one guy he can't beat them for what's to come. Still it begs me a question you're an Asari I study your species whom prefer diplomacy. It was fate that I meet you by chance."

"I was once a proud member of my race I got everything fame, glory and prestige I had it all because of my ideas and too seek a better future. I live my life for hundred years and meet other race. Thus one question I asked why is we still not progressing."

"I live a long life but nothing change as we continue using the same FTL device, same weapon and same shit. It was like were not progressing at all. Before we found about prothean we Asari have created other inventions to reach what we are now but when we found the prothean everything just stop the progress and no change at all."

"The other matriarchs are more interested of the prothean ruins and technology rather than progress. One day I decided talk to them of my idea of a new FTL device. You know what they did. They shrug and laugh at me like I was a lunatic."

"I try every place in the galaxy but all are rejected. My rivals use this opportunity to lower credibility calling me a fledging lunatic. Just like that my named was tarnished and being the laughing stock of the community. Rather than fall to despair I decided to create my own research in some place faraway."

"After years researching I manage to create a device that able to receive signal from far away but I discarded it and continue other research until the device reactive a signal and you appear."

"Yes I was curious of the device from a galaxy far way."

"You told about everything that intrigues me from the other galaxy and such we made a deal."

"A deal that you would summon more space beast on other planets and went on a rampage as they like."

"Still I question why the attack it, is it for revenge."

"Revenge... I not so petty to do it for revenge. I want my people no... the entire galaxy to open their eyes. You need to dirty your hands to change the galaxy. This is just the beginning a new era will begin."

At the same time the Spectre Saren was enrage not because the human manage to obtain the information of the beacon. It's the invasion of monster from another galaxy, was ruining his plan. The mercenary Fist was dead he was killed during the monster rampage and the Quarian was still alive.

The monsters rampage has cause all of his plans to fail, he heard that two new monster pop where the Thorian was located and the other one on Noveria already went on a rampage.

"This is unacceptable all my plans are ruin!"

The matriarch Benezia can only look at Saren without question. The sovereign also was dumfounded of the situation. The reaper machine has live for a very long time and seen many things but not giant monster with FTL capability. And there a humanoid being that was powerful made of light.

"Such primitive thinking is why this galaxy ready for the taking." a new voice was heard

"Whose there show yourselves?"

Emerge from the shadow were two glowing ominous orange eyes. On his chest was a purple Jewel and his body was covered with markings of red and black. His hands were sharp claws.

"You can call me Ultraman Belial."

I got this idea when watching Godzilla: City on the Edge of Battle. Sure it's not the same but it brought me ideas how or what would happen if giant monster attack the Citadel and other colonies. The shear seeing something and unbelievable like seeing living dinosaur from Jurassic world.
