>>41825549Fishious Rend has 85 BP.
It doubles to 170 BP if you go first.
Now, that would be absurd on its own, but we're just getting started. See, Fishious Rend is a biting move, and Dracovish gets Strong Jaw, so that's a further 50% power boost to 255 BP. It's STAB, so bring that up to 382.5 BP, and you can slap on a Choice Band for another 50% power increase to 573.75 BP. If somehow that's not enough for your sick purposes, it's a Water-type move so you can set Rain with Pelipper (it gets Drizzle now, see) and sic your chimaeric abomination on your foes with an 860 BP move.
Walls get murderlized.
The boost applies to switch-ins, so anything coming in to try and outspeed it gets murderlized too unless they have Water Absorb or Storm Drain. I think Arceus itself gets one-shotted on the switch even if it isn't raining.
Basically it bites real hard.
