The Mexican Death Bear is a greyish-blue bear which is considered to be very dangerous.
It first appeared in "Viva El Nomicon", but Debbie Kang was dressed as one beforehand for Halloween in "Night of the Living McFizzles". There was one in the Norrisville Zoo but Viceroy took it and turned it into a half-robot in order to fight the ninja.
Randy says that the bear is too strong and powerful to defeat. However, Debbie says that if their tummy is rubbed counter-clockwise they go to sleep.
- The Mexican Death Bear is based on the Mexican Grizzly Bear.
