Profile, Abilities and Weaknesses description is from The Transformers: More Than Meets The Eye, comic series published by Dreamwave Comics in 2003.

BIO:  Cloudburst was timid and dull until he became a Pretender. Once hidden within his new shell, he took the opportunity to reinvent himself and project an aggressive, charming attitude that is a complete turn-around from his real personality. His long-time friends among the Autobots continually try to convince him that he doesn't need his shell and fabricated personality to feel secure and better about himself, but he dismisses them and octs like he doesn't knON what they're talking about. Cloudburst is fundamentally mistrustful of others intentions, especially any Decepticons, possibly because he knows that he's constantly misleading people himself.

WEAPONS/ ABILITIES: Subject's armored outer Pretender shell is armed with an electrified lightning whip and a thunderbolt cannon that fires high-voltage bursts. Inner robot can convert into a high-speed interplanetary cruiser armed with -a particle beam cannon.

WEAKNESSES: Subject is reluctant to leave the safety of his shell, which makes him vulnerable in situations where his vehicle mode might be useful.
