Tyr is a fictional supervillain in the DC Universe. He first appeared in Superboy Vol. 1, #197 (September 1973), and was created by Dave Cockrum. His name is taken from Týr, the one-handed Norse god of war.
Abilities : Tyr is equipped with a powerful bionic gun in place of one of his real arms. The gun can fire powerful energy blasts, and can somehow control the minds of others. The gun can detach itself from Tyr's body and fly away, in the event he is captured.
