This comes from Ben's World of Transformers (http://bwtf.com):
Many fans were in an uproar over what they felt was an incorrect portrayal of their favorite Beast Wars veteran. We saw many instances of Rattrap being brave and formidable as a warrior in Beast Wars. However, that was when he was heavily armed, full of gadgets and confidence. Upon being reformatted into (what he perceives to be) a weaker form, that takes away some of that confidence. For a machine based life form to lose critical "parts" of himself is analagous to a human being losing a limb. It's an emotional trauma that must be worked through, and that is what we see in this episode - Rattrap working through the final stages of an emotional trauma, which can at times make people act differently than they normally would.
