Let's consider Albert Desmond, whose criminal tendencies motivated his scientific acumen towards a career as the costumed criminal known as Mister Element, a crime spree abbreviated due to the appearance of Earth-One's Flash. So in response, he adopted a new alias as Doctor Alchemy, possessing the transmuting Philosopher's Stone... and still met with failure. Eventually, Desmond joined the Crime Champions where he encountered his foe and another Flash as well as their twin teams. After a series of failed attempted at fame, Albert retired from crime to reform and marry his girlfriend Rita. Soon thereafter, Albert's cousin Alvin assumed the alias Doctor Alchemy which led to a duel between the two, with Alvin eventually joining the second incarnation of the Crime Champions then fading away. Albert's counterpart on Earth-Two, Mister Alpha, didn't have a twin himself, instead Alvin's counterpart was a red haired man like himself named Slicer who had attempted to obtain the Philosopher's Stone of his world from the evil Lorelei, rather unsuccessfully as it turned out (Lorelei and her allies Rumpelstiltskin and Gallifron were the dopplegangers in an Earth-Two adjacent dimension to the trio of terror Saturna, Simon Magus, and Troll King of an Earth-One adjacent dimension... each foes of the Justice Society and League respectively).
