"Ursaring, Hammer Arm!" Ursaring's arm glowed white, as it rushed towards Toxicroak. It swung it's arm at the smaller Pokemon wildly. Toxicroak dodged the attack quickly, it being faster than Ursaring helped a lot. "Double Team!" Toxicroak split into a dozen illusionary copies. All leaped up and attacked the slow Ursaring. "Drain Punch!" All the copies flowed through Ursaring confusingly. As the real one punched Ursaring in the face, draining it's health once more.
The Grunt laughed to himself. "Now grab it and use Slash!" Ursaring grinned evilly, it gripped Toxicroak by the chest and used it's other arm to slash Toxicroak, sending it flying backwards. Toxicroak landed on it's feet though, it took a damage, but was still able to fight. Ursaring then prepared it's next move.
"Quick, use Poison Jab! Also I knew you guys wanted to take over, what's up with this catastrophe nonsense? If you wanted the crystals so bad you should'a got them way back then before we did!" Toxicroak leapt forward and began bouncing around the Ursaring, Toxicroak attempted to confuse the Ursaring. Then slammed it in the back with a Poison Jab. Unable to inflict poison sadly, there wasn't an extremely high chance of that anyways. "Then use Drain Punch-"
Before Richie could finish the grunt commanded his Ursaring. "Fury Swipes, now!" Ursaring reacted quickly to aftermath of the Poison Jab, and attacked with Fury Swipes, all the attacks landed, damaging Toxicroak a lot. Toxicroak was attacked and grabbed, then flung into the water. "Too easy, your Toxicroak is weak, it can't handle my Ursaring!" The Grunt celebrated victory prematurely. He sure was very arrogant, and this wasn't the end of the battle.
'This is perfect'
Richie thought this to himself, as Toxicroak landed in the water, in a few seconds it emerged from the water, leaping into the sky, it looked quite replenished, though it still suffered from the damage it took. "Thanks to Dry Skin, my Toxicroak got some of it's health back, now use Drain Punch!" That last Drain Punch was tough to handle, Ursaring didn't have the speed to dodge, and was nailed, Ursaring fainted.
"Gah, oh no...the boss is gonna kill me..."
(Sorry if me using the Grunt is a problem)
