Waspinator's not the brightest 'bot in the Beast Wars. Megatron has classified the harebrained Predacon as expendable, much to Waspinator's dismay; he doesn't get much more respect from anyone else, either. His speech quirks don't help: he tends to refer to himself in the third person, and to most other people by nicknames like "cat-bot" and "two-head". He's also a bit too fond of the letter "Z" (those prone to witticisms might say he has a "lizzzzp").
Waspinator may be dumb, but he's not stupid. He has caught on to his lot in life, and tries to avoid his fate as often as possible... but fate always finds him. Thankfully, he's almost supernaturally durable, and has survived the most devastating and humiliating of defeats.
