Titan Undead

Titan (ティターン): An artificial Undead created from the Scorpion Undead (right-half) and Chameleon Undead (left) being fused by Hiroshi Tennoji into one monster that had access to their attributes and two buckles on its belt. Tennoji unleashed the monster for endgame, using Scorpion's Undead Venom and Chameleon's cloaking/disguise abilities to turn the Riders against each other. By acting that he fell under the power of Joker, Hajime Aikawa and the other Riders tricked Titan to reveal itself, defeating Titan by Blade King Form's Four Card with Garren and Leangle splitting Titan back into two sealed Undead.
