This is a pretty close match between these two fighters. I would likely take Garurumon to defeat Andromon due to the speed difference, but things get interesting once they are in their Mega forms. Garurumon has access to his Omnimon X form while Andromon has Craniamon. Craniamon’s defense is extremely good while Omnimon X is all about attack power. What helps Craniamon out a lot is that Digimon Savers easily had some of the toughest fighters. Luckily for Garurumon, Omnimon is one of the old fighters who has managed to stay high in the rankings. I believe that he can pull out a narrow win. Garurumon wins.
