I agree, a simple majestic nature suites Him. After all, He was eldest.. so He should be Master of the Universe. Zeus has to look the part of the King because he kind of took the position after playing lots.. not by inheritance.
Despite popular belief Hades was actually said to have been all right with the whole situation preferring to rule over the underworld, unconcerned with the realm of the living. He hated it when people escaped his domain though.
