Suggested by Sonic Slifer is a powerful dragon, but I don’t think he would be able to handle someone like Mr Majestic. Majestic’s speed and strength are on a whole different league when compared to Slifer’s abilities. Slifer’s blasts probably still would be able to get past Majestic’s defenses, but landing the hit in the first place would be nearly impossible. Majestic is more athletic and nimble in the air, he won’t be getting hit unless he gets overconfident. Mr Majestic wins.
