History
Marco San Antonio wanted to join the Avengers, so he devised a plan. He and his girlfriend Estelle would take down Thor who, now being powerless, he believed would be an easy pushover. The Avengers would then take him in, and having taken down Thor would make his reputation. His plan had several major flaws, not the least of which, Thor was no longer powerless. However Thor saw potential in them, and took them to Central Park where they helped him take down two rival gangs, with police caught in the middle.[citation needed]
