Rattrap

Rattrap is Optimus Primal's rival and secondary arch-nemesis in animation after Megatron. He is a sleazy, obnoxious rat who openly berates Optimus, constantly antagonizing him for years. Rattrap first appeared in the Optimus Primal short Optimus's Rival and ever since he has been battling Optimus for Botanica's affections.

Personality
Rattrap is incredibly selfish, rude, and constantly tries to get Botanica and Optimus to break up. Although he claims to love Botanica, he will flirt with nearly any female he sees. Botanica is rumored to be his ex-girlfriend. He seems to be hated by almost everyone, possibly even Megatron, as hinted at in ''Megatron's Christmas Caper. ''

Trivia

 * Walt Disney was orginally going to name Optimus Rattrap, but his wife insisted that it was too pompous for the character, so instead chose the name Optimus.
