Red Moon

Ally
Red Moon was character cut from the final Darkwatch game, described as;

"The leader of a small Indian tribe, Red Moon fought bravely to save the life of Jericho Cross and aid him in his journey across the West. Red Moon's fate was sealed when the two mixed their blood in a pact of brotherhood"

The mixing causing the noble warrior to be transformed into a Wendigo. An event likely to remind Jericho and the player that his power is a curse, not a gift.

Cursed Beast
"Red Moon's pact of brotherhood with Jericho infused his blood with that of the undead, twisting his mind and body into the horror that is the Wendigo. Bloodthirsty and absolutely insane, the Wendigo kills for pleasure as well as nourishment."

Trivia

 * Had Darkwatch 2 materialized, another Wendigo would have appeared.
