Even if it went up to 150 instead? Hmm, guess power creep got to it or it's Tapu meta now. Then again, not like I fleshed out the movepool much or anything.
(Also side note that I originally planned on it having base 125 Sp Atk; might've helped a bit in the power department even if it could screw over Darks. Not that Koko (the Tapu), Lele and Greninja care though.)
80 / 130 / 80 / 60 / 80 / 100
Spirit Rush (lowers the Defense and Sp.Def of the opponent's Pokemon when switched in by 1 stage)
Joint Strike (Physical / Fighting / 60 BP / 20 PP): The user attacks the target's legs or support joints, causing them to collapse. This attack inflicts more damage the heavier the target.
Base 60 power up until 50 kg (110.1 lb)
+20 damage for every increment of 20 kg (44.1 lb)
Caps at 160 base power.
[Basically, anything over 250 kg / 551 lb will get hit with maximum power.]
You can imagine this as a kick to the knee caps on stuff with legs [attack joints and people fall down]; other stuff can be support pegs or something (i.e. if you were to use this on Celesteela or something in-game / anime / whatever).
(Uh, copy parts of Sawk's movepool here since they're based on the same martial art, more/less. Change specifics later, though I probably just outclassed him, save for being unable to survive OHKOs / not get flinched.)
Pokemon with an inverse equivalent of Gyro Ball (faster you are than opponent, then more damage you deal).
(inb4 this lands up on Pheromosa/Deo-Speed sets)
