Kahmunrah

Kahmunrah is the main antagonist in the film's sequel, Night Of The Museum: Battle Of The Smithsonian.

When Larry activated the tablet, Kahmunrah and his minions came to life and forced Larry to give him the tablet.

Kahmunrah attempts to open the Gate of the Underworld, but the combination was changed, and then captures and traps Jedediah in an hourglass.

When Larry and Amelia return to battle Kahmunrah, he summoned an army of Horus warriors from the Underworld, but the statue Abe Lincoln arrives and defeats the bird-like warriors, forcing them to retreat back to the Underworld. While Amelia and the others were in battle, Larry then banished Kahmunrah into the Underworld, never to be seen and heard from again.
