Meet Ratchet

Synopsis
Bumblebee on Ratchet. Boy, this should be good.

Bumblebee - "Ok, let me tell you about Ratchet. He’s our chief medi-bot, handy with tools.  A lot of them built right into his robot body.  But his handiest tools are his supercharged electromagnets, which can lift anything for a runaway train to a runaway Decepticon.  Ratchet’s Earth vehicle mode is tactical medical response vehicle.  Kind of befitting actually.  We call Ratchet the Doc-bot, ‘cause he’s always patching up our circuits or pounding out our dents.  We also call him the grumpy old bot for…obvious reasons."
