Thaddeus Thatcher

Thaddeus Thatcher (サデウス・サッチャー), self-styled as Inertia (イナーシャ), was a member of the Death Trappers and a major antagonist featured in Black and White.

Inheriting a mutant gene from his father, Thaddeus gained the ability to slow down time for 10 seconds. Turning to the path villainy, he became a loyal member of the Death Trappers and went up against Blake's group, serving as the archenemy of Marcus Allen after framing him for various crimes.

During the invasion of Bianco Academy, he was confronted and defeated by Marcus in a final duel and was sent to the Vault.

Slow Dancer
 Like many other people in the Evershade world, Thaddeus, as a result of a mutant gene, has access to a Meta Ability dubbed "Slow Dancer." By altering the flow of time relative to himself, Thaddeus can create the illusion of "moving at superhuman speeds." In addition, this ability also creates a protective barrier via the pulse wave that Thaddeus generates when he activates Slow Dancer.
