The GameStop Exclusive variant cover of Black Panther #1 by Dale Keown shows the Black Panther/T'Challa riding some kind of motorcycle-like vehicle. In the background, we see flames, as if he's leaving an explosion. His claws are drawn to suggest he is preparing to enter a battle.
It appears that the vehicle is flying or hovering above the ground. The idea that he possesses a transportation machine is a nod to Wakanda's reputation as a technologically-advanced nation.
There's a pencil and ink sketch of Keown's cover here.
