Professor Flux is a regular attendee at the annual Villain-Con.  Though he may be someone out of place amongst the many villains who show up there (either as guests, as exhibitors or as guest speakers), as he appears to be the least villainous of the lot.  He presents the very image of the quirky, eccentric but studious and dedicated scientist--white lab coat, black rubber gloves, and a balding pate. He is, however, quite the genius, having invented the very first successful time machine! 

At the 1968 Villain-Con, the professor decided to reveal and demonstrate his new invention...going forward in time on several occasions in order to bring future iterations of himself back to that year in order to assist him with his many other experiments.  That is, until one of his future selves accidentally killed him, thus wiping out of existence every future iteration of the poor professor!
