Biggest difference for Bass would be that Mattel's comes with only one Buster, but it has a firing projectile. Also, Mattel's Bass has a closed cloak that's removable, but you can't really make him poke his arm out or anything.
He also comes with a Vulcan1 Battle Chip for the PET toy, if anyone cares.
