4 looks awesome, and is easily number three in my list. If it weren't for the fact that both Aqua and Soda wear dresses. 4 would be number one without a doubt.
Also, would you be offended if I were to ask if we could change Tanzanite's weapon from the Monk's spade to Hooks Swords? I just think that they would make for a more interesting weapon, but would compeltely understand if you wish to keep the original weapon.
@Akayaofthemooneh, sorry about that then.XD Yeah, they're awesome.
Edit: While I do love the fourth picture, I don't think that it would fit all that well. I just think that it would be a little weird for what essentially looks like a biker girl to be wielding a Monk's spade. Maybe some amalgam of the first and second pictures? Four arms, Robe-like but still open, maybe her bangs covering the top set of eyes? With Aqua's abundance of hair, and Soda's uncontrollable hair, I'm sure that it could happen.
@pyroman Besides, I don't pick random weapons for the fusions. I actually try to find a weapon that incorporates both the gems' weapons and what weapon I could see happening if the two original weapon were to be put together.
