Powers and AbilitiesEdit

While Otacon is physically incompetent who doesn't even understand the basics of fighting, he is a complete genius who can hack the most protected things with ease. He is also a master engineer and creator, as he was the intellectual behind Metal Gear REX (one of the deadliest war-machines on the planet), the Mk. II, and the Mk. III, a harmless miniaturized Metal Gear with a taser whip and invisibility feature.
