Dr. Tarsan

The genius behind the Dangaioh project, Tarsan was at first intending to sell Mia and her friends as living weapons to Garimoth. After the incident with Pai and Rol, he decides to get even with Garimoth and joins the four youngsters, providing them with technical support. The Dangaioh kids regard him as a mentor, but aren't above bullying him when he mentions he might sell them to others if the potential buyers meet his standards. (Source: Wikipedia)
