Shoutmon: Aw, come on!
They left the Coliseum and then Giovvani has appeared
Giovanni: Well, I guess that lab geek is a bit stubborn for you, kids.
Komasan: Who are you, Zura?
Giovanni: Let's just say I'm a friend. So you want to enter the game, right? I believe I have a way to get you in.

Professor Oak: What? Where on earth did you get the pass?
Shoutmon: It doesn't matter! Now can we enter the game?
Professor Oak: Chill out, dragon. Okay, let's start the preliminary.
They are in the Games and they are fighting the Heartless
Professor Oak: In all my years I have never seen a fighter like to you and your friends. You might even be strong enough to fight the Pokemon.
Then they saw a Liquid creatures passing by them
Komasan: Who's he, zura?
Professor Oak: Hm, he's a very strange creature. Before you arrived, he defeat many opponents in this battle.
They are fighting the Heartless and they defeated it
Professor Oak: I've never seen a Digimon and a Youkai would fight so good. Too bad, Ash wasn't here.
Shoutmon: Who's Ash?
Professor Oak: Ash Ketchum of pallet town. A Pokemon Trainer about their age. He's out to become a Pokemon master by defeating the toughest Pokemon and gym leader. Too bad he's Battling with my Grandson. Gary oak in another arena, or else he would appear in the battle soon.
Giovanni: Those Creatures are you're opponent's. I want you to destroy them.
Choas: So, the great leader of the Team Rocket is afraid of those kids? Listen, I like to help you. But the contract said-
Giovanni: I'm the one who wrote the Contract, you think I don't know about this! I know is say you're only to required to destroy Ask Ketchum in the Tournament and get his Pikachu, but in order to do so, you have to defeat them. Beside, the Tournament is just for fun so why don't you lighten up? I know you're here for a reason to relax, huh?
Giovanni: Well, I must admit, he has a bit of attitude for this but is still a sucker to my plan.
