The story went like this.
Once everyone else had found an opponent, Greninja eagerly picked out Regirock.
To be honest, when Regirock first saw the frog, he dismissed him.
Then Greninja underwent the Bond Phenomenon, created more than a hundred Shadow Clones, and surrounded Regirock with a barrage of Rozan Rising Dragons.
That was when Regirock learned the hard way that the Pokémon World was a 3D game!
Holy shit, I can actually get knocked into the air and never come down!
Frog after frog uppercut him skyward. Regirock was stunned senseless.
His brain had never been much good to begin with. After all that tumbling through the air, he nearly shut down completely.
He was going to be stun-locked to death!
Nearly two minutes later, Regirock had completely lost his bearings.
"I surrender! Urgh! Stop making me fly!"
He sprayed vomit everywhere midair. He really couldn't take it anymore.
He'd never flown this long in his life. He'd never suffered an indignity like this!
He wanted to cry!
"Croak!"
[Don't you want to fly a little longer?]
[There's a certain Legendary Pokémon who's dreamed of flying his whole life!]
Greninja's question went straight for the heart, though it seemed to hit a certain other Legendary Pokémon even harder.
"No more flying! I give up!"
Regirock landed and vomited helplessly, looking utterly wretched.
Greninja found the sight a little disgusting, so he took pity on Regirock and gave him a shower with Water Pulse.
"Croak!"
[Rinse your mouth out. Your breath stinks!]
Regirock didn't dare argue. After a quiet thank-you, he hurriedly used Greninja's Water Pulse to clean himself up.
Luckily for him, Greninja was in a good mood and had used Water Pulse instead of spitting water at him.
Otherwise, the sight of Regirock washing up with water Greninja
