Bio: A nameless gang of thugs who wanted to make an impression on
Gotham's underworld, these men decided the only way to get noticed was
to enhance their strengths via cybernetics. After kidnapping the wife of
a noted medical scientist, Dr. Peter Corso, they forced him to enhance
every member of the gang with a specific trait and weapon:
• Bullwhip - enhanced with cybernetic whips, controlled by his thoughts.
• Kneejerk - enhanced with sharp cutting instruments, most notably
fixated on his kneecaps.
• Krul - enhanced with a metal armor, which is hid in chambers under his
skin under activated.
• Terrapin - enhanced with large, deadly fists.
Forced to enhance these thugs, Corso secretly dubbed them "The April
Moon Gang," the name coming from a treasured song between he and his
wife. With each members' abilities cybernetically enhanced, they now
have the power they so desired. The only thing they didn't count on,
however, was running into Gotham's protector.
*Judging by the ending of "April Moon", it appears as if Bullwhip died.
