A huge robot with an array of weaponry ranging from frying pans to lasers. Most of his moves have almost no start up time and zero hangtime with the application of an advanced technique known as fast fly.

With the acquisition of unfly mode, be prepared to be perpetually stomped, frying panned, laser beamed and hyper sentinel forced. One mistake on sentinel will cost you 80% of your life. A huge robot that is feared by scrubs.
1) Sentinel just owned magneto, storm, and psylock without getting a scratch!!
