Here's Extriverse Arcee! If you can guess why she's got rat features... then you've probably watched Beast Wars haha!

Anyway here's her info/headcanons/etc:
• She has a stubborn streak so wide you could park Metroplex on it.
• Has a bad habit of holding onto grudges.
• Airachnid is her arch-enemy after the spider bot slaughtered her young partner/teammate. The fact Airachnid doesn’t even remember his name upsets Arcee to the extreme.
• She will absolutely make dares/bets with you to do the most stupid wild things but to be fair to her, she’ll do things just as wild as what she suggests to you. She won’t dare/bet you to do anything she wouldn’t. Which is saying something given some of the things she comes up with.
• Absolutely the bot yelling “CHUG CHUG CHUG” during parties.
• Despite her appearance, her front teeth do not continually grow, but they regenerate fast and strong.
• She grinds her teeth together when stressed but also sometimes when relaxed.
• For a long while she relied more on her speed but now she’s been training physical strength too and has become quite an expert in hand-to-hand combat.
• You her friend? You her fam, she will fite anyone who hurts you.
• Her tail is actually mostly the seatbelts from her car mode. Ultra Magnus tried telling her to retract them once but she made her point by whipping him in the knee with said tail and making him fall over. She proved her point.
• 27’9”
• Holds her drink damn well and has sometimes played the part of being “unassuming” and “demure” in order to wreck someone at a drinking contest.
• She lost her temper with Cyclonus once after he bit through their fuel pipes in a battle which almost scuppered their escape ship. She attacked him and bit his neck/shoulder as a sort of eye-for-an-eye revenge attack. Unfortunately, that just left her open and she kinda forgot she was ‘out-jawed’.
She lost an arm to Cyclonus but thankfully he didn’t eat the limb and she got it back and reattached but not after she threatened to bludgeon him with the severed limb.
• Has a slight Brooklyn accent.
• Bench pressed Hot Rod a lot. Still did it while he was Rodimus too just to mess around.
• She shut herself out a lot after Airachnid killed her partner and had many years of being chipped away at before she finally exposed herself to being friends with others again. As such she tends to make a point of at least trying to converse with someone whose 'alienated'/cut off from others in order to try and help them like others did for her.
• Finds “I’m Batman” jokes hilarious.
• Chills a lot with Elita-1, Chromia and the rest of the crew.
• Bots worry that with her attachment to her friends being so strong she may genuinely “flip her shit big time” if one of them were to be severely hurt/killed, especially given past losses.
• Despite all of his problems she actually complained least during Rodimus’s time as leader understanding better that he needed the unconditional support during such a massive shift in his life. She may or may not have also threatened to punch people’s teeth out for being insulting about him, he was trying his best damn you.
