“One member is gone…”
The Legion suffers saboteurs, spies and turncoats more often than any other half-dozen superhero teams. Here, it’s recognized that one of their two newest members – Karate Kid and Nemesis Kid – is a double-agent for the aliens Khunds, the warlike race whose name you must never say when you have a head cold.
The Legion are quick to accuse, and luckily Nemesis Kid is even quicker to surrender, since they actually accused Karate Kid at first and Nemesis Kid only mistook the overheard confrontation for having his cover blown. Also, the guy’s name was “Nemesis Kid”, how could the Legion NOT know he was the baddie?
