Mega Greninja

Best moveset

Mega Greninja can learn 18 combinations. Water Shuriken 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 Greninja you catch today cannot learn it. The best set it can learn now is Water Shuriken and Brutal Swing, worth 16.7 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.

Best moveset against each type

Mega Greninja does not have one best moveset, it has 2. Which one wins depends on what you are attacking, because a move only gets its bonus against something weak to it. Best against Ground, Rock, Fire.

Same maths as the headline number, run once per defending type: level 40, perfect attack IV, and the target's own type taken into account. Sorted by damage, so the top of this table is what Mega Greninja is actually for.
