Kain

"WE ARE LEEJUN!"

HE LIVES IN DEATH!! PEACE THROUGH POWER!!

Wrong Kain and wrong game, dumbass.

Anyway.

Kain is a Black Legion space marine Aspiring Champion, and Eliphas's field commander/adjutant, who appears in Retribution. He's one of the two chaos heroes who never speaks outside of battlefield cries, probably because he doesn't require a cool voice to be awesome.

Tacitly considered to not be as much of a fuckup as Neroth, although he does annoy Eliphas by getting downed by what appears to be a five-man scout squad at the beginning of the campaign.

Despite not even being the commander of his respective faction, he beats Kaptin Bluddflag in combat if well-kitted, and is reasonably similar to Apollo Diomedes in combat potential. What a badass.

Kain is notable for being able to use almost all of the same power swords as Eliphas, alongside being the heavy-weapon hero of chaos, which makes his role equivalent of The Ancient or Sergeant Merrick, trading out mobility for hitting power in melee, and plasma cannons for a man-portable autocannon. He can alternately spec into being a poor-man's plague champion absolutely covered in flies, a decent melee combatant completely overshadowed by Eliphas, or a heavy weapons guy who pops all the metal boxes.

He also has the same voice-actor as the Khorne Berserker units and Chaos Marines from Dawn of War 1.
