Eventually, Captain America finds Zola hiding in an alternate dimension, Dimension Z, where time moves at faster rate than on Earth. There. Zola has built a massive fortress where he is making a massive army of genetically altered soldiers with the intent of conquering Earth. In the initial assault, Cap rescues a genetically engineered infant boy (Zola's son, Leopold). In the decade stranded in Dimension Z, Cap raises the boy as his own son, Ian. The two take up with the peaceful Phrox, and eventually lead a rebellion to stop Zola's forces, now commanded by Zola's daughter, Jet Black. Ian is later captured by Zola, and brainwashed to accept Zola as his father again, but eventually breaks out of his control, only to be shot by Sharon Carter. Eventually, Carter sacrifices herself to destroy Zola and his fortress, allowing Cap and a now reformed Jet to escape back to Earth, where only seconds have passed since his arrival in Dimension Z.
