Who??
The battle against Pansage was bull. He got lucky with both Watchog and Blitzle. His only legit win that I can even remember is against Krokorok.
Yanappu:Not bull, Mijumaru took a nice amount of hits and did some damage to Yanappu. Used a rebounded Water Gun to retrieve his hotachi and go on to win, also showcased his hotachi's defensive abilities.
Miruhog:Hit it with Shell Blade and got confused but still hit it Aqua Jet and gained a tie in the process, moves still are able to hit under confusion.
Shimama:Trained for non-hotachi combat and had upped speed, scored quite a lot of Tackles against the opposition, managed to out gut Shimama when their Nitro Charge and Aqua Jet's fused and crashed. Won the battle completely legitimately.
Dokkora:Knocked it out by overpowering it fairly easily, showing off his growth as a Pokemon in physical strength.
Waruvile:Used Water Gun while spinning to eliminate Sandstorm and goes on to win by linking together three super-effective moves one after another.
Even the battle against Sanzadora at the league he lost showed him hitting it once with each one of his attacks, that's pretty damn impressive considering Gantle barely did anything and Chaobu only managed to win because of the prior damage to it. That's pretty damn impressive and as I said before when the plot isn't working against him he's able to win or show his prowess decently.
