Look within your local lab and you will find a friend and boy...
It's Skyfire!

• His size leads him to have joint problems, specifically in the knees, as his frame type shouldn’t really be as tall as he is (approx 39-42ft, Seekers should be 36 max).
• He’s soft-spoken and mild-mannered.
• The other Autobots worry about him but don’t know quite how to confront him. They worry about his mental state as he missed a significant amount of the war and his last memory was of a peaceful Cybertron so he never had a big time to adjust.
• Was frozen on Earth millions of years ago during an expedition, when the planet was almost 99% covered in ice and life had not yet formed.
• Has no idea he’s pretty much the reason Starscream joined the Decepticons in the first place. He would not be flattered or impressed if he knew.
• Speaking of; he now has a rather bitter relationship with his former friend and doesn’t understand why he shot him in the back and left him for dead. Skyfire knows full well he had his faults before the war but now he’s just cruel. It does leave him feeling quite lost and angry to have lost a friend.
• He wasn’t around for the building of the original trio of Dinobots but boy did he have a blast joining in with adding Swoop and Snarl to the team.
• He wasn’t sure what he felt when he saw the ash pile/smudged streak and crushed crown that remained after the Unicron wars. He is also unaware of certain ghosts.
• Absolutely bombarded the humans with questions when he got the chance.
• For a while he fell back on being almost religiously scientific, possibly as a way to cope with the jarring change in his life, it didn’t help he felt alienated by the Autobots for a long while and merely used as a transporter as he could fly and take a teleporter with him to bring other Autobots to the Decepticons.
• He is responsible for making the Autobots a ground bridge to deal with the latter part of the above note.
• Cosmos thankfully helped him break out of his odd coping method by informing him the other Autobots weren’t ignoring him or being cold, they too just felt awkward and unable to be of proper help to him, after all what could they really do to make waking up to find your home planet almost destroyed by war and anyone you were friends with are either dead or an asshole any better?. Cosmos mentioned a few others probably felt awkward because he was like a ‘untouched reminder’ of how they and their species used to be before Megatron.
• His social status within the Autobots gradually improved after that.
• Never had a trine.
• During Galvatron’s ceasefire, Skyfire made a conscious effort to contact Cyclonus, he felt like there could be some grounds for friendship in the fellow oversized Seeker after all, did he have the same joint issues? Did his back occasionally hurt around the wing base? Maybe if he used this chance to be friendlier with the Decepticons, the war was less likely to start back up again! Whenever he did manage contact, however, he found him to be blunt and quite curt with his answers and generally a bit awkward. Perceptor later pointed out this was fruitless as Cyclonus was not really a “full” Cybertronian anymore and his alien frame was perfect for his size, unlike Skyfire’s. (Skyfire later also found out Cyclonus was just plain awkward not rude)
• Upon hearing that “anymore” Skyfire now joins Perceptor in eagerly hoping for a chance to examine Unicronian anatomy.
