Nathan Summers was born a time-traveling, telekinetic, bionic mutant badass. Once Apocolypse infected him with a techno-organic virus, he was forced him to use a deal of his powers to resist it from spreading. Even with the TO virus, he was still one of the most powerful mutants in the universe! Not to mention a powerful character in the MvC2 roster! Watch out for his Hyper Viper Beam.
