Fake Pokemon 2000

System: Game Boy

My mother bought me a fake Pokemon 2000 from Thailand about 1999 around.. it was not Pokemon, but it was way better.. but it was japenese and the maincharacter lived in a small town near a big tower and you got a robot pet.. like a big robo cheetah with mounted machineguns.. then you get into the tower and had to fight with other robo creatures, which dropped equipment for your robo cheetah.. on some point it freezed and a i trashed it
