The Marvel's mighty god of thunder may not be the mightiest Avenger after all, as Thor learns to his own dismay in a new promo for Thor: Ragnarok.

In the brief scene, which further highlights the humor of director Taika Waititi's film, Chris Hemsworth's Thor attempts to launch a spaceship on Sakaar, only to be told by the computer that voice activation is required. Repeated attempts -- "god of thunder," "prince of Asgard" and, finally, "strongest Avenger" -- are frustratingly denied.

Enter Bruce Banner, who tries his password, "Banner," which the on-board artificial intelligence immediately accepts, responding, "Welcome, strongest Avenger," leaving Thor with a little egg on his face: "Uh ... what?"

The scene is interspersed with fight scenes featuring Thor and Hela, Thor and the Hulk, Hulk and Fenris, and, most dramatic of them all, Hulk and the fire demon Surtur.
