Mega Blastoise
Water
Best attacking moveset: Rollout and Hydro Cannon, worth 15.7 damage per second against a neutral target.
Best moveset
Mega Blastoise can learn 15 combinations. Rollout with Hydro Cannon does the most damage per second of them, at level 40 with a perfect attack stat. Same-type moves get the 1.2× bonus, and the cycle assumes the charged attack fires the moment it has the energy.
That set is legacy. Hydro Cannon is only obtainable with an Elite TM or from the event that gave it out, so the Mega Blastoise you catch today cannot learn it. The best set it can learn now is Rollout and Hydro Pump, worth 13.4 damage per second.
Stats and moves come straight from the game's own data files. Every number on this page is a raid and gym number, not a PvP one.
