Suggested by Sonic Inspector Gadget has a lot of great gadgets but they will be a double edged sword against Bullseye. Bullseye can turn anything into a deadly weapon so if he gets ahold of these items, then that’s game over. Additionally, Bullseye already has quite a lot of tools of his own which he could use to take down Gadget. Gadget isn’t particularly fast or experienced so that will be the end of him. Bullseye wins.
