1) As one of the Spineless Ones who refused to wear a mechanical spine, Mojo’s main mode of transport was a metal chair that moved around on spider-legs. He also had a large mechanical “tail” that protruded from the back of the chair, which housed numerous interface devices as well as a large weapons array. [Longshot #3]
2) When Mojo came to Earth and set up his Yellow Eye surveillance company, he decided to disguise himself. Going against his hatred of standing upright, Mojo somehow squeezed his enormous body into a black leather suit. In lieu of showing his face, Mojo had a rectangular opening in the chest that allowed him to see through. To complete this strange ensemble, he wore a purple dinner jacket and yellow gloves. Because why not? [X-Force (4th series) #7]
-) After escaping back to Mojoworld, he went back to using his spider-leg chair once again.
