The strongest in showdown were Mordekaizer, Heimerdinger, Orianna and Annie.

However if we're talking straight up fight then Skarner has one of the strongest damage outputs in the game since his Q almost refreshes when he autos someone, and his shield comes up every 5 seconds.

And then there's Fiddlesticks. If they can't stop his drain no-one can kill him. If they can stop his drain then he can fear them and run away.
