It is physically very similar to the Velocidrome, the only key difference being the pale blue colouration and the presence of a frost sac.
Abilities
Not only does it sport more powerful attack power and higher defense than ordinary Giaprey, it is also capable of spitting a frozen substance that can immobilize prey and foes alike.
Behavior
The Giadrome is quite territorial towards other monsters and other Giadromes. It travels alongside its pack and coordinates attacks using barks and calls.
Monster Hunter Freedom 2 / Monster Hunter Freedom Unite
The alpha leader of a pack of Giaprey, the Giadrome sports a beautiful crest. Larger than a Giaprey, any hunter silly enough to encroach on its turf will be frozen in a hail of ice.
Monster Hunter Generations Ultimate
Alpha monsters that lead Giaprey packs. They sport splendid crests and are much bigger than Giaprey they lead. They spit ice with deadly accuracy, and woe betide the Hunter who gets caught in it.
Capcom-Unity announced the 9th of March, 2011 to be Giadrome Day, the first day of a series of Monster Days Capcom-Unity created that originally happened every Wednesday of the week.
Unusually, the Giadrome model was changed between MHF2 and MHFU; in Freedom 2 it has red claws, whereas in Freedom Unite the claws are blue.
