Powers: Taboo was an accomplished sorceror. He was able to use his mystic skills to manifest a number of effects, most of which have yet to be seen. A few examples of his powers were his abilities to form magical shields, perform incredibly complex spells, and imobilize others.
In addition to these powers, Taboo had accumulated a number of magical texts and items that possessed magical powers. At one point, he was also able to access the Darkhold.
