A birthday party for Brainiac 5 turns into a deadly event in Adventure 378 (March 1969), but gives Karate Kid his most notable achievement during Jim Shooter’s tenure on the Legion.
Superboy, Duo Damsel, Karate Kid and Princess Projectra are the guests at Brainiac 5’s birthday. Apparently the other 20 members of the Legion simply don’t like him? At any rate, those who don’t attend are the lucky ones, as Brainy and his guests all get poisoned. They have only 24 hours to live.
While Brainiac 5 desperately hunts for a cure, Luornu goes to spend her time with her parents, Sueprboy flies off to do as many good deeds as possible, Projectra hangs in a park and feeds birds, and Karate Kid decides to die in battle, and seeks out the Fatal Five. He plunges into an attack, and defeats the entire group single-handed!
The five gather together as their deadline approaches. At the last minute, Brainiac 5 remembers the Miracle Machine, but collapses on the way there. A mysterious man enters to gloat, and then time freezes. WTF?
Concluded next issue.
