Bido

Bido was a chimera created in the Fifth Laboratory after escaping it he followed the homunculus Greed. Before his transmutation he was a member of Martels military special ops team which instigated the Ishval revolt. He was fused with a lizard or a gecko this enabled him to have a firm grip on surfaces when climbing and to use his tail as a bludgeoning weapon. He is bald and speaks in a raspy hacksaw voice though its unclear whether this is a result of the fusion or not.
