Who's the worst antagonist?

[BumblebeeCody*]

It's hard to say worst because so many are forgettable or bland. Eggman/Robotnik

Code:

comes to mind. Has an IQ of over 300 and can't defeat a hedgehog when Homebase lorries can.
Builds giant machines and mechs with weak

spots that can be taken out by jumping on them
Dunno. Just eh.
(Also, the pointlessness of the "antagonists" of Sonic Lost World).
