Abanak

History
Abanak,(AKA "The Ghost of Booder Falls"), is Native American living in Booder Falls and the last living descendant of the tribe Samuel Booder VI’s family wiped out, the Alsonquin Nation. When Raphael was demutated by Bloodsucker and later lost, Abanak found him and returned him to his brothers, whom he led to Booder's factories at the river. After Booder, the CEO of the industrial plants poisoning the river, was slain by Bloodsucker, Abanak accompanied the Turtles (after passing the mantle of "The Ghost of Booder Falls" to three children who had been earlier attacked by Bloodsucker) to the source of the river in the highlands of Vermont. Facing Bloodsucker in a final duel, they came to realize Bloodsucker was sent by Old Man River, whom they finally met in person. Bloodsucker was reverted back to a normal leech by Raphael, and absorbed the now-embryo Old Man River, whose magic had been used against him by Splinter to reverse his great old age after Abanak failed to stop him himself. Abanak, who he revealed in his final moments of regression to have the same power as he, took Old Man River’s place as caretaker of the river.
