Kicking things off is the Season 2 philanthropist voiced by Keegan-Michael Key.
Sebastian St. Clair is a self-righteous snow leopard and slacktivist who is more concerned
with getting his face in pictures at warzones and erecting statues than actually doing some
Keegan-Michael Key's arrival is strange to say the least because he is putting on an accent to his
character. Sebastian St. Clair is a British billionaire, and while cast
members have provided voice work for other characters (Alison Brie voicing the
character Vincent Adultman for instance), it
does seem strange that Keegan was cast in the series but chose not
to use his normal voice.
One possibly theory is he personally took a look at the design and script for the character and settled on the notion that Sebastian spoke not just with an upper-crust tone, but with an accent that reeked of self-congratulations and disillusioned ideas
Whatever the reason, it works. The voice fits the
character perfectly as he pontificates how brilliant he is or how badly he
needs a duty free giant Toblerone.
