Actually there was a Transformer that changed from a wolf into a chainsaw!

Chainclaw was his name. Appeared in the 2023 movie apparently.
So he was just hanging around on Cybertron as a chainsaw but needed to disguise himself to not appear threatening on Earth and picked a giant wolf?
I've never really gotten the hang of the origin story of these guys other than, "We're cool toys."
LOL, and apparently the guy is a hypochondriac to boot:
