Anyone ever know why his arms are detailed AND colored differently? I have the Japanese Big Convoy version, but never followed Beast Wars Neo.
This is a can of worms.
What most people agree on is that he lost one arm in battle (probably against Magmatron) and replaced it with a prosthetic.
As far as I know, it's only vaguely alluded to, and never explicitly shown in the anime or manga.
I love it, it augments the character of Big Convoy and makes his toy pretty unique. I don't know of any other toy that has an event or story element sculpted into it!
Even the fingers are different on the other arm!
