Yeah I hated Rattrap when I first saw the series. But he soon became a most likable character.

Yet it's the same actor who voices Rattrap also voices Dinobot, Waspinator, Silverbolt, Quickstrike and Cicadacon! He also voiced Omega Supreme, Strongarm, Backstop, Snarl and Jetfire in the Unicron Trilogy English dub (though Jetfire was voiced by a different actor in Cybertron). Scott McNeil is arguably the 2nd most versatile Transformers voice actor next to Frank Welker.

He's an Australian-born Canadian too. (^_^)
