(Avengers I#101 (fb) – BTS) – With Robert Fisher unable to attend due to an upcoming chess world title, eastern Europe’s Yuri Sporadnik was contacted to play chess against the super-computer NIMROD.

(Avengers I#101 (fb) – BTS) – Leonard Tippit was tasked with killing comrade Sporadnik to “save the Earth” by the cosmic Watcher.

(Avengers I#101) -  Picked up by the Avenger Hawkeye, Yuri Sporadnik was taken to a Stark plant where he was to play chess against NIMROD. Realizing that they were already off-schedule, Sporadnik hurried the start of the chess match. During the heated match, Sporadnik had to briefly leave for a bathroom break and upon his return, he touched a specific pawn and was poisoned by Leonard Tippit, who had secretly hidden inside NIMROD to assure his plot was successful. Taken immediately to a hospital, Sporadnik became comatose.
