From The Halo Mole:
A little too eager, Deadpool is someone who would much rather charge head-on at a problem than think it through as other contestants might. Made obvious during testing, he lost the most lives out of any participating contestant. This could potentially prove problematic down the line when faced with tough obstacles possibly affecting his fellow contestants who may become annoyed at his impatience. Fortunately, he is a very good shot and has an excellent knowledge of how the Halo engine works. Should he come through in the early eliminations, he has the potential to go all the way.
