A servant of Knives in the series Trigun. Legato and Vash are able to telepathically communicate because one of Vash's arms was grafted onto Legato. Legato is very similar to Knives in that his goal is to see the end of humanity. Speaking of psychic powers, Legato possesses psychokinetic powers with enough potential to murder people in an artistic manner (see the show to see some examples).
Being both smooth and cool at the same time, the term originates from internet-rapper ZachSherwin's similarly named music video on made-up slang.
"Tom is such a subtiledouchebag. He needs to learn from Zach, who's more Legato Gelato!"
