A Velocidrome is a Raptorial Bird Wyvern and the alpha male leader of a Velociprey pack. Its large, bright red crest over its blue hide signifies to other Velociprey that it is fit to be their leader.
In the original Monster Hunter, Velocidromes were always surrounded by Velociprey, which constantly spawn. Hunters have to face one or two of them in a Quest. In later games they may be fought alone and away from their minions. They are one of the earlier monsters to be encountered in the various Monster Hunter games (with the exception of Monster Hunter Tri, which they are not featured in). They can usually be found in the Forest and Hills or the Jungle regions. There are several related species, including the Giadrome, the Gendrome and the Iodrome.
Among the raptorial Bird Wyverns, only Velocidrome and Gendrome have no breath attack.
Velocidrome does not appear in Monster Hunter Tri, but a similar role is played by Great Jaggi, a raptorial Bird Wyvern that can summon younger individuals of the same species.
A Hard Core version of Velocidrome appears in Season 10 of Monster Hunter Frontier, with improved attacks and a new look making it the most powerful of the Dromes in the series.
Aesthetic differences include red eyes, hooked beak, a different shaped crest and drooling when in Rage mode.
New attacks include a spinning bite followed by tailwhip, a side-to-side jumping body-tackle and super jumping that causes small dust covers and small rocks popping up showing it is breaking the ground as it jumps. (Requires Quake resist +2 to escape).
SR100 HC Velocidrome is well known for killing hunters in one hit in even 600 defense.
In Monster Hunter Frontier G3 Velocidrome gains 3 new attacks in G rank. Super high speed charging, 5 new types of spit attacks and a combo jump in air > spit any of its 5 types of spit > land > crest uppercut attack that launches hunters.
White and Black spit causes Defense Down status effect.
Red and Black spit causes weapons to loose sharpness.
White spit causes Fatigue like walking.
Brown spit causes the Soiled status effect.
Green spit has the odd affect of a Farcaster sending the player back to camp.
In its introduction Scene, the Velocidrome is seen to raise its head and roar to call on Velocipreys, but Velocidrome never does this in battle during 1st and 2nd generation games, until the 4th generation.
Its HC variant uses this move as a taunt, however.
