Bart Thatcher

Bartholomew "Bart" Thatcher, self-styled as Inertia, is a superhuman criminal from Centre City. After Kane's particle accelerator incident, Bart gained the power to slow down time for 60 seconds every three seconds. After escaping from CCPD, Bart challenged Lightspeed and defeated him, going on a crime spree while fighting the Stryker. However, he was defeated by Lightspeed in a rematch and was sent to the Vault.

During Shadow's raid on Ultimate City, the Vault was destroyed and Bart roamed free.

Trivia

 * Bart's name is a nod to both DC Comics supervillain Thaddeus Thawne, other wise known as Inertia, and superhero Bart Allen, the fourth Flash, hence the name Bart and Inertia.
