Yellow

The yellow sphere is the 2nd ally of Luxor. Like his friends, he's a member of the Sphere Club.

The other spheres and Yellow can stop the pyramids as much as they can, unless of course they're killing them themselves! Yellow may seem irritated, but he does have a secret weapon that will get him out of any tight spot. Lightning powers that is. (Unfortunately the shock of him also can be triggered by unexpected noises, sudden movements and evil pyramids.) Just like his friends. His enemies are the pyramids.
