He finds the ninjas and makes his guards get them so he can hypnotizes them too. Mike and Owen manage to escape before they are caught. Dr. Eternum captures Mike though and hypnotizes him to be evil and good.When he finally captures Owen and Amanda he has Mike attack them thinking that he is hypnotized. Mike however isn't effected by the hypnosis it might be because Amanda turned the power off early. The ninjas defeat him and his guards. He is then sent to jail.
