Winsen is a Blackguard and member of The Mighty; Kip Guile's Blackguard squad. He is a mountain Parian, but without their usual tall, thin build. He still has a fair amount of baby fat.

Although he is a blue and yellow bichrome, his true talent lies in his nigh-supernatural skill with a bow. However, he is also cynical, nihilistic, and at times cold and distant. He is amoral rather than immoral; having no apparent conscience or moral code. Despite this, Winsen remains extremely loyal to his brothers-in-arms and has not shown any apparent cruelty or sadism in his actions.

Winsen is one of the slave Blackguards.
