Clifford used modified Alucbierre ships to leap to a Type 3 Civilization and then he conquered the rest of the universe, then the multiverse, then all of reality, flattening out and straightening branes, creating extradimensional spaces, etc.
Now Clifford had a viginitillion to the power of Graham's number to the power of 10 to the power of a googolplex to the power of 163 Graham's numbers x one vigintillion subjects.
All their adoring worship made Clifford swell and swell with size until he was the largest thing save for God in existence.
Simba and Mufasa tried to attack him but he was too large.
