Tatsugiri

An interesting little dragon, Tatsugiri is well known as the 'boss' of Dondozo, and it has more attack than the great gulping catfish, and... that's about it. It wants to compete in two VERY powerful metas, but it just doesn't have the power or moveset to do so. On the bright side, catching a Tatsugiri means you've got a free plate of sushi!

Best PvE Offensive Moveset

• Tatsugiri operates best as a Water Type attacker, so Water Gun and Surf are the way to go.
• Muddy Water is too weak for offense, while Hydro Pump is on a par with Surf, but with a far higher energy demand.
• Tackle is borderline useless, while Outrage has little to no real utility on Tatsugiri.

Best PvE Defensive Moveset

• Tackle has solid neutral coverage and stronger defensive performance than Water Gun.
• Muddy Water is generally the best option for a defensive Charged Move, as it comes out early and frequently. However, it's also fairly weak,
• Outrage and its raw power/reasonable energy cost is also a great choice.... though it's a fairly easy to dodge.
• Surf falls between Muddy Water and Outrage.
• Hydro Pump probably won't have a chance to fire off.

Water Gun has solid average performance, Surf has solid performance for relatively low energy, and Outrage can deal solid damage. Really not much else to say here.
