Charizard: Aerial IG, gains a large forward jump, that could be used to cross gaps that the other weapons can't, as far as lore goes. In combat it makes it one of the best weapons for chasing after fleeing monsters or closing the gap in general. The Aerial attacks without buffs gives you the double hit of the triple buff, while with the red(might be triple, can't remember exactly), you get midair cartwheel type attack that hits a few more times. So it isn't redundant by any means; it's also not the best mounting weapon anymore either.
