Optimus had experienced his fair share of odd situations throughout his life. That was only natural when you were the leader of the autobots and had lived as long as he had. He had battled space monsters, shapeshifters, old gods, undead.
But he had to admit that interdimensional travel was a first for him.
At least he could feel at ease knowing that he had landed among friends, even if they were a tad different from the versions he knew.
"You're so tall!" the human girl, Sari, exclaimed with awe, eyes shining as she craned her neck to look at him. With her pigtails and excited personality she reminded Optimus a lot of Miko.
The Bumblebee of this dimension did not appear as impressed. He crossed his arms with a humpf and glared at Optimus with critical optics. "Well, he's probably super slow, slower than a snail!"
"I bet he's super strong too..." Other Bulkhead murmured, decidedly more impressed. He stared at Optimus' arms dreamily.
"He's got a strong spiritual presence, that's for sure," the two-wheeler designated Prowl commented. His optics focused on Optimus chestplates, leaning in closer. "And there's something else. It almost feels like-"
"Would people get out of my medbay!?" Ratchet, who appeared to be just as high strung as the one in his own dimension, interrupted. He waved around a datapad like Wheeljack with one of his swords. "We don't know what kind of viruses his world have and if we're susceptible to them! We could have a potential pandemic on our servos!"
"Viruses!?" Bumblebee stomped his pede and pointed an accusing digit at Optimus. "You guys see? This bot is nothing but trouble! I say we send him back to wherever he came from as soon as possible and get our own Optimus back!"
Bulkhead piped up. "That might be more difficult than you think, Bumblebee. You see, he portal that brought him here was due to a space bridge malfunction that quite frankly had a one in 3 billion chance of happening and even if we were to find a way to replicate this we'd also have to find a way to get his dimension do the same thing on their end."
Optimus cocked his head, intrigued. "Do you know a lot about space bridge technology, Bulkhead?"
"Uh, yeah, I guess I know some things," he responded, meekly. He fidgeted with his servos, not quite daring to look Optimus in the optics.
Ratchet interjected. "Don't sell yourself short now," he chided, giving Bulkhead a reassuring pat on the shoulder. "Bulkhead here is the foremost expert of space bridge technology. Ain't no bot that knows more about the stuff than he does."
Hearing this, Optimus smiled. "That's incredible! While the Bulkhead I know is a brilliant mech in his own right he does not possess such expertise in space bridges. How brilliant!"
At this, Bulkhead finally managed to meet Optimus' optics. There was a faint blush on his faceplates. "Really? I'm not really all that- Uh, I mean, what's your Bulkhead like?"
Optimus' smile grew fonder. "He's one of the bravest mechs I've ever had the honor of knowing. The only thing that can compare to his immense strength is his kindness." Gazing down at the young bot in front of him, he placed his servo on the his shoulder. "The two of you are appear very much alike, in that regard."
Bulkhead's blush grew in intensity, his optics becoming round like saucers, flickering from Optimus' face to where his servo was on his shoulder back to his face. "Oh geez, I don't know what to, oh stars-"
"What about Bumblebee?" Sari suddenly asked, clambering on top of some barrels to be seen. "When you first appeared you said you had a Bumblebee in your universe as well, right?"
Bumblebee, this universe's version, crossed his arms again. "Whatever kind of person he is, he can't be faster, or more handsome, than me!" He paused. "But yeah, what about him?"
Optimus laughed. "There's no way I can praise him enough. Bumblebee is a true hero, through and through, and he's saved my life more times than I can count."
At this, Bumblebee visibly preened. "Oh yeah? Sounds kinda like me then. You know, I've also saved our Optimus' life a couple of times already." He jabbed a thumb at his chest. "Some call me a hero too."
"I don't doubt it," Optimus replied and somehow Bumblebee managed to puff out his chest even more.
"Yeah, well, why don't you tell me some more about my other dimensional counterpart and my- I mean his, heroic deeds? Just so we can compare notes."
Ratched sighed loudly and dragged a palm down his face. "Great, just what we need, Bumblebee getting yet another ego boost."
Prowl leaned in closer to the medic. "At least he's not openly hostile towards our visitor anymore." The corner of his mouth twitched. "He got so mad when this Optimus asked him if he wasn't too young to be an autobot when they first met."
Ratchet couldn't help but snort. "That alone made all of this worth it. Sigh, I just hope our Optimus is alright."

"What do you mean I'm the leader of the autobots? Ultra Magnus is right there! What even is a Matrix? WHAT DO YOU MEAN I'M THE CHOSEN OF GOD?????"
