Organguru is a Support Pokemon that will effectively double the damage output from a pokemon in a double, or triple battle.
It can easily help pokemon that takes 2 turns to ko an opposing pokemon into pokemon that will ko in 1 turn.
I can forsee Earthquake, Discharge, Heat Wave, and Rock Slide being a common move that will be "doubled"
Also, I can assume this also means this will allow pokemon that use buff moves to use those moves twice, as well.
Organguru can effectively take a turn away from the other trainer.
This monkey will be terrifying in doubles / triples.
Wishiwashi was able to defeat the opponents thanks to the orangatang.
