Slipstream is blue, has mismatched eyes, and, as a trainee, does what Ironhide says. He looks like he turns into a fast car - or maybe that's just what he wants you to think.

Slipstream and his training group were pressed into service by Ironhide to rescue an Autobot prisoner from a Decepticon stronghold. Skyblast, Signal Flare and Strongarm distracted the automated defenses, allowing Slipstream, Ironhide and Bumper to blast their way into the base. The base was manned by a single, solitary Swindle, who promptly surrendered, allowing the Autobots to free the prisoner.
