  | Killer Wasp | Justice Society of America vol.1 # 9 | The son of Wildcat's foe Yellow Wasp, Killer Wasp was the test subject of many of his father's experiments. Yellow Wasp mutated his son into a half-insect/half-human hybrid. He has enhanced strength, agility and endurance. He also has wasp-like wings on his back which allow him to fly up to speeds of 50 mph, and the ability to shoot electrical blasts from his hands. Soon after, Yellow Wasp kidnapped Wildcat's son, Jake. Rather than slaying the hero's child, Yellow Wasp began to think kindly of Jake, raising him as a (some would say favorite) son. Killer Wasp soon killed the two in a fit of jealousy. Shortly afterward, he joined the Injustice Society formed by Johnny Sorrow. The group of supervillains attacked JSA headquarters while most of the team was out, with only Wildcat in the building. Killer Wasp faced off with Wildcat, who taunted him, claiming he was too scared to face him in a hand-to-hand fight. Wasp took off his mask in response, and engaged in open battle. In the end, Wildcat was victorious. During the Infinite Crisis storyline, Killer Wasp popped up as a member of Alexander Luthor Jr.'s Secret Society of Super Villains. Killer Wasp shows up again in JSA All Stars #2, again fighting under the command of Johnny Sorrow, as part of the Injustice Society. He is killed shortly after when Johnny cuts open his chest and removes his heart. |
