Formally known as 'Wackbot' to those within the Marvel vs Capcom 3 community, Sentinel was once a beast in version 1.0 of vanilla MVC3 before receiving nerfs in future patches and game updates. In my view, Sentinel is still more than capable of achieving great success in a tournament setting, but it's undeniable that he's much weaker than he used to be.
My goal here is to explain how and why Sentinel was considered to be so strong, and I've split the video up into parts to make it easier to digest. Plenty of characters in vanilla MVC3 were extremely viable, but Sentinel was always one hit away from winning any game...
