Suggested by Sonic Gallade is a pretty powerful Pokemon. I always thought she was the more powerful final evolution form compared to Gardevoir. That being said, Beelzemon has the absolute edge in power. His skills with a gun should not be underestimated and he has a chaos mode to tap into as well. Gallade might be able to land some hits in but she won’t be dealing enough damage to win. Beelzemon wins.
