Nasus or Teemo?
I've been looking for a champion that starts to do heaps of damage if left alone, and I thought of 
(Q) and 
(R).
Which one?

and
both have limitless damage if given time to farm. While relies on laying traps.
If you want to be a brutal, hulking one-shotting/tower killing machine, then go .
If you want to be an all-powerful deity controlling the battlefield, choose .
If you worship Satan and enjoy occasionally sacrificing a goat to spread fear, doubt, and poison among all who oppose you, choose
just dont pick against
nasteemo ez
If you want to be annoying, then would be your better choice.
Hm.
So Teemo is suggested here?
Nasus
Assuming you are looking for a top laner, of the two I'd recommend Nasus because he scales much better and is very durable. However, he doesn't really deal much damage early and you need to have farmed stacks if you want to be a damage threat, though his ultimate and E have good base damage to help make up for it.
Another good choice would be Mundo because he has a lot of innate damage and can match many champions for damage dealt even when built near full tank. Sunfire Cape and Thornmail (or maybe Wit's End) are the only damage items you really want on him, though he can work well with Liandry's Torment.
