Humanized Sullivan for my "The Secret of NIMH" AU; Mrs. Brisby and the Bund of NIMH. Sullivan Ray was a former soldier serving Jenner's military arm, in charge of supply base until the attack and imprisonment in NIMH where he was experimented and became a IM-Human. His family and many of comrades killed, he follows Jenner as the vengeful IM-Human avenged them by killing enemy soldiers and scientists.

Although, initially voicing little concerns to help late Jonathan's family, he was occasionally scolded by his own wife Macy (my OC) who is a member of the IM-Human guards/soldiers. When Jenner plots to kill Nicodemus and take over as new leader of colony Bund, Sullivan was reluctant as he began to feel concerned witnessing Jenner's descent into darkness.
