Susejo was a Choi and possibly the very first victim of the sarlacc of Tatooine. Susejo fell into the Great Pit of Carkoon when he was very young, around four thousand years before the Battle of Yavin. After being captured by the sarlacc, he passed the time trading stories with an unlucky Jedi that shared his fate. By 4 ABY, his personality had merged with that of the sarlacc, which had kept him alive for thousands of years while it absorbed his consciousness. Susejo introduced himself to Boba Fett when the bounty hunter suffered the same fate, and at that time his personality was indistinguishable from that of the beast, controlling its actions and speaking on behalf of the creature.
