Kevin Trench is hypnotised by George to act like Erasmus Gore. (Shock, Horror!)
Erasmus Gore is Thermoman's arch-enemy from Ultron.
When journalist Kevin Trench makes George and Janet's lives a misery with his false stories on Thermoman, Janet has an idea. George and Janet addresses The Press with Tyler and Arnie standing by them, George claims that Trench is determined to discredit Thermoman because he os actually Erasmus Gore. Trench can't believe it and says "who the bloody hell's Erasmus Gore?". George then uses a superpower to make Trench say that it's true and he was Eramus Gore. George then breathes Trench into the air to make it look like he's flying. George then plants a black helmet and crude plans for taking over the world in Trench's flat for Police to find before leaving Trench on the Eifel Tower. (Shock, Horror!)
It is unknown whether Erasmus Gore is made-up or actually exists, the fact that he has never menaced George in My Hero suggests not.
