Gypceros

A wyvern that can generate bright flashes of light with its prominent head crest. Its rubbery hide resists damage, and it can spit a poisonous substance. It is quite timid, however.
Destroy the crystal by striking the monster on the head while the crystal is recharging, and then the Gypceros becomes unable to stun hunters anymore.
BradyGames, Monster Hunter Official Strategy Guide, 2004, p. 84
A wyvern that is strange in both looks and nature. Its timidity keeps it constantly running about, and it rarely stays in one place.
