That's not how the game works. You have to start out with the little crap cute weak ones and then murder your way to something cooler.
Take your little monster, and go look for some other little monster to beat the crap out of. Rinse and repeat until it grows or you find something better. Some guy should teach you how to stuff the things into their little travel containers once you cripple them enough to make them submit.
If that isn't doing it fast enough find some kid with a lot of bugs and kill all his bugs and take his money, it makes them grow faster.
