>stats>ability>movepool>typing All obstagoon really needs is at minimum base 100 attack, priority extreme speed and sucker punch, and belly drum in its movepool and it's easily OU. Judging from its design, it looks like Obstagoon would lose speed and put on a bit of bulk in hp and defense, but speed doesnt matter with priority. It wouldn't even have to fear mach punch if it sets up belly drum. E-speed goes first.
Its typing isnt even that bad.
