Hulk/Flash Versus scenario
Who would be more powerful with comparable (but not exact) powers?
Start the characters off at base strength/speed of sound.
1. Hulk at base strength can now move at speed of sound. The madder he gets the faster he gets, as well.
2. Flash moving at just the speed of sound is at Hulk base strength. The faster he runs the stronger he gets.
How fast/strong can the characters get? Who winds up overall more powerful in your oponions?
