While Corsairs are often Aeldari who leave the craftworlds to find themselves, the Red Corsairs of the Chaos Space Marines are far more bitter and twisted. They are led by Reave-Captains, renegade warlords who follow Huron Blackheart.
The Reave-Captain has a choice of three different heads, two backpack toppers, two bandoliers, and can be armed with a power sword or power maul, and a plasma pistol or a (no doubt stolen) trinket, making it easy to customise your leader.
