SkunkyArt | DeceptiSpoon

Has the same 'stutter' as he does in the RiD15 show.

Transforms into a small unidentified car-like vehicle.

Eats very slowly and gently (think like those videos of crabs).

Was 'owned' by Gyconi for a majority of his life, wore his collar happily and dutifully obeyed the mob boss.

'Fixit' isn't the name he came online with. No one knows what is "real" name is, if he ever had one. Gyconi would hit him over the head, point him at something and bark 'fix it'. So he began to respond to it like a name.

Accidentally ruined the alliance between the Decepticons and Gyconi.

Witnessed Gyconi's death and it was somewhat traumatic for him.

Excellent at repairs and basic medical duties.

Quiet.

When the Autobots picked him up as the sole survivor aboard Gyconi's ship he was very jumpy and nervous.

Ratchet ends up adopting him.

It's likely Ratchets gruff outwardly attitude initially attached Fixit to him as it reminded the Mini of Gyconi. Naturally, Ratchet is much nicer than Fixits former "owner" and as such the more parental bond quietly formed.

Mock his boys stutter and watch how fast Ratchet can repurpose you into a toaster.
