"Secret Move! I can see through that! Sword of Black Knight! Is that it?"
Aegis Counter is Taskmaster's Hyper counter. He unleashes a flurry of air tearing slashes (colored yellow, orange and red) at the opponent, backstabs them (in the style of the Black Knight) and shoots them at the back of the head with Punisher's Colt. Though this is a counter move, it does not appear to work against projectiles.
