What are some bad *** lizards to keep as pets?

I have a some experience with snakes, lizards, frogs, tarantulas etc, so I can probably handle most lizards, I'm looking for something lol I really like monitors but as i already have one another would be great as long as it doesn't require a mive enclose like my sav, I don't really have enough space, so something decently sized but still pretty bad ***.
