Not to long ago, I found the game known as: Outernauts on Kongregate.
It's similar to Pokemon, only in Outernauts, you have a choice of 4 or 5 starters, instead of just three. (I picked the fire starter, by the way.) At first glance, it doesn't even seem like a "catch monsters" sort of game, the title makes it sound more like travel in a space ship with graviton particle beams.
The game has some really good humor too, but it's not the kind you should show to little kids. It's more for teenagers and adults or some where in that age group. But this is mostly just my opinion, why not go play it yourself? Just click the link earlier in this post. Have a good time!
