Further exploring the comic book trope of the spin-off character (see my list of Female Versions of Male Characters). Clearly there is something of a double standard, as female versions of male characters abound, while the reverse is much more limited.
Earth-11 male version of Big Barda
Was modeled after Catwoman
Evil male counterpart to Jenny Sparks
Male version of Dream Girl
In continuity he's the ancestor of Blink, but he was actually based on her
While an amalgam of several characters, he takes most strongly after Jean Grey/Phoenix (especially in appearance)
Briefly took the title of the Wasp after his wife's death
Phantom Lass
There have been multiple Phoenix hosts, but he's technically a spin-off of the original (Jean Grey)
Male version of Power Girl
Harley Quinn
Although there are differences, he was inspired by the original Red Tornado (Ma Hunkel)
In the Kingdom Come reality he adopts his mother's former Darkstar role
One-time holder of the Cheetah identity
Shadow Lass
Male version of Supergirl
Since his father is unknown, he's primarily based on his mother, Crystal
Son of the Scarlet Witch and the Vision, he takes after the former
Male version of Wonder Woman from an alternate reality
Son of Raven
