[Kaiba sure did call them that. If circumstances had been different, and duel monsters was more popular here than Pokémon he might have been able to see some merit in them. Perhaps if he had a better rapport with any of the trainers that might have been possible too, but mostly the trainers looked down on his monsters or scoffed about cardstock. Same verse, different mouth spouting it or sometimes it was just the body language that said it all.

The trainers were too full of themselves from Kaiba's perspective. And considering who he is... well. he was an expert in the field of ego]

Hmph, they are.

[Not even feeling like refuting the different 'world' theory]

Someone should, and seeing as I'm the only one who can...

[He raised his left arm which has his duel disk strapped to it and pulled out a card to show it to her]

These are duel monsters. They don't come from inside a pokeball, and I currently can't really summon them since the device required isn't functioning.

[Maybe he wasn't going to go into a full rundown now, but he wanted her to at least know that differences existed]
