The one on the left is called Bruce and the one on the right is called Roger.
Roger looks a bit like he's related to the Triangular wave sisters, but he's a relatively sloppy dresser. Roger hangs around capacitors, especially those connected to resistors, the like of which often hang out at the 555 Tick-Tock club
In contrast, Bruce is more of an individual.
Is there a purpose to this question?
