"Trainner" Games?

Does anyone know of any GOOD "Trainer" type games? like Pokemon, Digimon, or Monster Ranchers?

Dragon Quest Monsters Joker 1 & 2. But I am not fully sure if that fits what you are looking for.
Spectrobes from Disney

that Spectrobes any good? I've heard different things about it.

Spectrobes isn't great, I wouldn't try it if I were you, but you can take the risk and like it.

It's okay. You may not like it much.
The sequel, Spectrobes: Beyond the Portals is better.

monster racers on the ds is a awesome game plus with the multi racing its a fantastic and addictive game

I don't know if this counts, but Brain Training.

Monster Rancher DS
