Wish we had more of Makeshift because we have no info on what he was doing before Screamer rounded him for that mission..
I can imagine him and Soundwave being cryptic prankster duo.. And also i feel like he would be intrigued/fascinated by humans ability to mimic
I know, right!? I wish we had more information about Makeshift, especially with his powers. Can he take the frame of any mecha, regardless of frame-type, or is he limited to similar sizes? Is the ability only a surface change, or does it warp his very CNA? How does he train each character? Method acting?
While I can see Soundwave being a cryptic prankster, I don't see him officially teaming up with anyone. If anything, Soundwave would either Makeshift's tricks to go unimpeded or secretly guide some setups as a low-key hobby that doubles as a morale booster because laughter is good.
Makeshift would arguably be among the first of the Cybertronians to see how well humans can mimic others. Not just voices and sounds, but appearances as well. He and Knock Out would get along over historical cosplay, YouTubers that focus on fashion (coughBernadetteBannercough), and Makeshift can double as a model for any of Knock Out's tailoring explorations.
He would be so down to join sci-fi and fantasy conventions and ren faires as he can walk around as himself with mass conversion and win many cosplay competitions (and heckle at so many dedicated 'true fans' before being dragged into said arguments for real).
And on a side note, he would definitely be the first 'con to clang humans. He has the advantage of becoming many humans' robotic/completely armored bedroom dream.
