The most cute, beautiful, sexy, awesome, ravishing, admirable, etc.etc. thing on the planet. I have one for my battling team and a couple of users here have encountered it and seen how deadly it is.
Design:The best of gen 5. Better than conkeldurr and volcarona, etc.etc. Its an evil dragon based on an hydra. Whats there not to like.
Wifi battling: Sadly this is the place where he takes a beating. He isn't bad but he isn't the best either. Its stat distribution is disappointing. 98 base speed is terrible if you have no way to boost it and its too fast for trickroom. It has mixed offenses but its generally a better idea to just use his special attack. Go with modest.
However this thing gains points for his movepool. Its just insane. It has literally every offensive move it wants. Draco meteor, dragon pulse, flamethrower, focus blast, surf, earth power, outrage, eq, u-turn, charge beam, surf and even more!! And it also has an incredible support movepool. I even wrote about how it can abuse taunt.
