Yvain Robotnik (a.k.a. Eggman the Second) is a recurring antagonist from Sonic the Hedgehog: Bermuda Triangle. He is Dr. Eggman's "son", and the very first Bionik created by the evil scientist.


Yvain Robotnik is Dr. Eggman's alleged son and accomplice at the latter's evil schemes. Eggman decided to create a Bionik - an elusive kind of Badnik - inserting his brain patterns, so that he could take over the Bermuda Triangle more easily, hence Yvain is dubbed "Eggman II". Whilst Eggman himself is fought at the Kernel City, his son is subsequently fought in the other seven levels of the game.
