- — In-battle Check
The GrizzlyBear (Grizzly in Mother) is a stronger enemy version of the Bear and the Polar Bear. This is one of the most dangerous enemies on Mt. Itoi. It has ridiculously high stats and almost always attacks first. He preforms continuous attacks, as well as the dreaded final blow. It will usually kill characters in one hit, but goes down in one hit if the player uses PK Beam Gamma or PK Fire Omega.
Interestingly, this creature and its family are similar to the Ursa Major's (which is also called グリズリー in japanese) from its kin series, Dragon Quest, with Dragon Quest III having introduced the monster just a year before.
- The In-battle Check is a reference to the popular fairy-tale The Story of the Three Bears.
