Introductions

Optimus was looking at the map of earth with red dots pinpointing clues about Allspark shards. Ever since it's shattering the autobots have been eager to find the shards and collect them before the cons did.

Shaking his head after thinking of how the spark was shattered due to that mad AI named Ultron. He got up of his desk and shut off the map as he looked outside to see the construction of Autobot City being made.

elita one bumblebee, hot rod, arcee, springer, ironhide and Ratchet were helping along with their human allies construct the city. Optimus shifted his attention to where the main defense were located that Jazz, Blaster, and Hound were taking turns on that job. Optimus had to be thankful to the Avengers to convince the Government to have a piece of land as long as it is under their watch.

As he was walking out to see how things are going, Prowl came up besides him with a data pad.

"I assume you're done with reading the map as usual?" He asked as he looked at the data pad while walking with Optimus.

"Indeed, my friend." Optimus told him. "Autobot City has made a lot of progress since the humans allowed is to build a city here."

Prowl chuckled at his leader's words. "You can thanks the Avengers for convincing them."

As they contained walking Prowl added, "by the way you got several messages that I was asked to deliver. Professor X from the X-men is asking for a meeting to discuss with you" he then adds a data pad to Optimus, "plus a request for a visit by the pope, and a visit/meeting by the inhuman king named black bolt." He adds two more data pads to Optimus.

"A meeting with other leaders of other superhero organization..." Optimus mumbled, unsure if it was a good idea to meet them since he needs to settle things were with the reinforcements that are about to arrive.

"Though I could send a message to them asking to wait till after today due to some "business going on." For you if you like." Prowl offered as they get near where both of them could see Spike and bumblebee finishing up a wall while talking.

"Ugh. To think that we'd be set for construction right after that damn AI destroyed the only thing that could possibly restore Cybertron." Bumbled grumbled as he used an Engineer lighter to fix the wall.

"Come on Bee, at least you'll be sharping up your skills when you do find the shards" spike offered as he helped finished up on his level.

"Yeah, and we're suppose to train these new Recruits from Cybertron as well as the Avengers right while constructing cybertron?" He reminded his friend as he finished his part of the wall.

"Well you never know if these new recruits are just old friends." Spike said as they hear a sound of a ship coming as they all turn up to see a Autobot ship coming down.

"Heads up, boys!" Springer told them through their comms. "Incoming friendlies are arriving."

"Well better see who these new guys are." Bumblebee said as he transformed in his Camaro as spike got in as they drove towards the landing platform where Optimus and prowl are.

"So, who do you think they are?" Spike had asked the Autobot leader, getting off of Bumblebee before he transformed into his robot form.

As Bumblebee was about to answer a voice rang out from the ship, "After these years we're back on earth!"

"…Scrap…" Prowl could mutter after standing silent for a few seconds. Before Hot rod, Springer, or Arcee could ask, the door open as a red bot with a gun on the shoulder come out as he stepped out of the ship as he held his hands up, "Just smell the air bro!"

"I think we could all hear, soldier." A voice came out as a big blue, white and red bot came out as fellow bots came out of the ship.

Spike did a double take as he must have be imaging that he was seeing two robots with the exact same design. "Um... is it me, or...?"

"That's ultra Magnus, and trust me. When the war on cybertron began, he looked like Optimus underneath the armor before he decided to get an upgrade." Bumblebee explained as Ultra magnus went to Optimus along with a white and blue female bot as ultra Magnus shakes Optimus hand while female salute him, "It's an honor to meet you sir. Excuses sideswipes excitement here."

"Hey!" Sideswipe exclaimed as Ultra magnus shook his head and look back to Optimus, "It's good to see you again old friend."

"Indeed." Optimus said before looking at the two female autobots. "Ah, and I see you brought them in?"

Spike looked at the two female autobots. "And who are they? I don't recall Elita or Arcee mentioning them..."

Ultra Magnus nods as he answers, "Ever since your message it was accounted that I would go ahead with a group of autobots, Strongarm wanted to be with me as part of her training."

"While I wanted to come to see my friend's friend." Windblade answered as she and bumblebee gave the high five to each other.

Spike had a guess to who the Autobot was talking about. "Do you mean by either me, my kid, Kamala or both of us?"

"You Spike, Meet Windblade. She's someone I knew on cybertron before the war began," bumblebee answered as windblade looked at spike.

"So you're the one who Bee played the video games with while he was here." Windblade answer as she lower herself to offer a shaking hands.

"Um, yeah." He spoke, shaking the bot's hand. "Truth be told, it was my dad who introduce me to Bee."

"I see you got reinforcements, Prime." Everyone shifted their attention to Captain Steve Rogers. He was with Natasha, Stark, and Kamala whom were accompanying him.

"Ultra Magnus, Steve rogers aka captain America of the Avengers. Steve rovers ultra Magnus." Optimus said as he introduce them both

Stark looks at the two female bots. Despite them being robots, he can tell that they were attractive and beautiful if they were human. Still, he was aware that they were dangerous. "I see that the boys may like the new company they're about to have?"

Windblade and strongarm just gave him a look that said "excuse me". As they were about to open their mouth before bee, Wheeljack spoke.

"Alright, Alright." Wheeljack put his hands up, blocking the two fembots and Stark. He then began to lecture Ironman. "Look, Stark. I know you were joking there. But, don't let your playboy side get the better of you. Remember what I always said during my lectures? Be mindful of what you say."

"Yeah, try not to hit on them since you have a wife." Bumblebee reminded the billionaire playboy.

The avengers snicked at what was said as Tony stort of face palm of what his teacher said as Optimus looked at the rest of the bots of Sunstreaker with his insecticon pet name bob appear plus Skids and mirage, "to those who are here I welcome you, to those who have been here before welcome back."

"Good to see you, Sir!" The newly arrived Autobots greeted their leader.

"Prowl and Elita one will be your guide as for those who been here before, report to Jazz and Ironhide for review, once you are all set, report to Wheeljack for vehicle forms." Optimus instructed as all bots nodded.

As Bumblebee and Spike saw them leaving, questions were raised in the latter's mind. "So, Bee?" Said bot looks back at him. "How do you exactly know that bot and what are your relationship with her is like?"

"It's a long story." Bumblebee told his human friend while scratch his left cheek in embarrassment as he was going to explain his history with that particular female Autobot to his old friend.

Like the story. Well, this is a buildup to another story right after finishing that First Avengers/Transformers story. For now, you all have to wait.

Crimson Soldat: Yeah, this was unexpected. But to make the story more popular, we decided to make something interesting.
