User blog comment:Sifter66/Which Champion has the best/coolest Ultimate Ability?/@comment-5194571-20130129230747

Singed has two ultimates. R and /L. Both are equally powerful.

In all seriousness, it's his R that makes Singed so strong yet deceptive. It's a hyper steroid and he's near-impossible to kill with it active, but he never gets banned out.
