I’m nearly a month behind in posting this but it’s honestly timeless and showcases the magic of Pokémon (and, by extension, RPG mechanics). In a 7-star Greninja Tera raid, HoodlumCallum and his team took the blue frog in one hit thanks to some phenomenal set up (as outlined by a commenter):
-Stonjourner’s Power Spot boosts all moves’ power by 30%.
-Koraidon’s Orichalcum Pulse sets up sun, triggering Great Tusk’s Protosynthesis, raising its Attack by 30%.
-Greninja starts the battle with Toxic Spikes and Double Team, but it doesn’t matter.
-Oranguru’s trainer uses an Attack Cheer, boosting everyone’s offensive stats by at least 50%.
-Koraidon uses Screech, halving Greninja’s Defense.
-Stonjourner uses Gravity to completely negate the earlier Double Team.
-Greninja uses either Hydro Pump or Ice Beam on Great Tusk, triggering its Weakness Policy and doubling its offensive stats. Hydro Pump cannot miss because of Gravity, and Ice Beam cannot freeze because of the sun.
-Oranguru’s Symbiosis triggers when the Weakness Policy is used up, giving Great Tusk its item. Its item is a freaking Choice Band, so that’s a 50% boost AGAIN.
-Great Tusk drops the Mother of All Headlong Rushes.
-Great Tusk’s Attack (rounded down) = 397 x 1.3 x 1.5 x 2 x 1.5 = 2322.
-Greninja’s Defense is cut in half.
-Headlong Rush’s power is effectively 468.
-Greninja the Unrivaled is obliterated in one turn.
