*Long before Captain America led the Avengers, he joined the original Human Torch, Namor the Sub-Mariner and more as the mightiest heroes of World War II - the Invaders! With young adventurers Bucky and Toro by their side, they charged into overseas action, taking on Nazi threats such as Baron Blood, Master Man, Warrior Woman and the vilest of them all - the Red Skull! Along the way, the Invaders made new allies including Union Jack, Spitfire and the Liberty Legion. And witness the heroes of two eras collide, as the Invaders battle alongside the Avengers and the Fantastic Four! *Source: marvel.com
