Alatreon

General Notes

• Even if believed to have mastered all elements, Alatreon never uses all of them at the same time. On the ground, Alatreon uses only Dragon-element and Fire-element attacks. When it turns blue and spends most of its time in the air (see below), Alatreon uses Ice-element and Thunder-element attacks, and if it falls on the ground, its common attacks (like its charge) will lose their usual effect (for example, the charge won't inflict Dragonblight anymore).
• Alatreon is very vulnerable to Paralysis and Sleep. However, as an Elder Dragon, it never gets exhausted and isn't affected by any Traps or Meat.
• Alatreon is weak to Ice Element (then Water) when on the ground, and weak to Dragon Element (then Fire) when hovering in the air. It is slightly weak to Thunder when on the ground, but immune to it when in the air.
• Front claws and both horns can be broken, wings can be damaged and tail can be severed for two extra carves.
• Both horns must be broken for Skypiercers to be obtained in the rewards.
• Unlike the Elder Dragons from previous MH games, the tail can be severed at any level of health, like usual monsters, but this won't affect Alatreon's power.
• Alatreon doesn't have an aura like Kushala Daora or Teostra. However, it is able to muster its power and energy in its horns. At that moment, the horns will be surrounded by little sparkles. After a few minutes, it will absorb those sparkles and turn blue, before hovering around the area and starting a thunder and icy rampage for some minutes. In this Flight Mode, it is difficult to deal significant damage to Alatreon. In addition, it is more aggressive and more powerful. Breaking both horns or making it stagger by focusing on the head when the horns are surrounded by sparkles will prevent Alatreon from using its true power.
• Using Flash Bombs will make Alatreon fall onto the ground from its Flight Mode.
• During its Flight Mode (see above), Alatreon will sometimes cause wind which will make hunters fall over, much like Kushala Daora's wind barrier. This will happen during aerial charges.
• If Alatreon hits one of the two ledge walls of the Sacred Land during a charge, its horns will become stuck for a few seconds.
• At the end, it should destroy the wall, unless it is staggered. It cannot be ledged when both horns are broken.
• If Alatreon's tail is cut during Flight Mode it will glow blue instead of red even when Alatreon lands.
• Alatreon's horns begin to sparkle or turn white signaling it is ready to revert to the Flight Mode. If its head or horns take considerable damage during this time, the sparkles will disappear, postponing Alatreon's Flight Mode.
• Alatreon's roar requires HG Earplugs to block.
• Alatreon, Teostra, and Lunastra have the same sound effect when roaring.

Monster Hunter 3

• You can no longer hunt Alatreon in Monster Hunter 3 because the online servers have been shut down.

Monster Hunter Portable 3rd

• Alatreon can be unlocked by clearing all double monster quests.

Monster Hunter 3 Ultimate

• In MH3U, no sign of charging is visible on its horns and it appears that it can almost randomly go into Flight Mode. It will sometimes do its precharge move before jumping back and entering Flight Mode. Breaking both horns does no longer prevent Alatreon from entering its Flight Mode.
  • Alatreon entering its rage mode almost always results in it going into Flight Mode.
• In order to unlock Alatreon, the player must clear all the village quests.
• G Rank Alatreon is exclusive to an Event Quest.

Monster Hunter Generations

• Alatreon can be unlocked by reaching Hunter Rank 80.

Monster Hunter World: Iceborne

• Alatreon was added in Iceborne's fourth title update on July 9, 2020 (UTC).
• Unlike in previous games, Alatreon can control all of its elements freely, regardless of the active mode. However, it will use the element Fire or Ice more in Fire Active and Ice Active respectively. While in Dragon Active, it will use all element attacks at equal frequency.
• Alatreon's physical appearance has seen some slight changes in the New World, with the wing membranes connecting higher up its body, the head and neck being noticeably smaller, and the tip of the tail bearing a hardened bone point.
• This is the first time Alatreon has a unique icon as opposed to the icon that represents all other First-Class Dangerous Monsters.
• Alatreon now has 3 different modes, called "Active", which are Fire Active, Dragon Active, and Ice Active.
  • Alatreon will emit a powerful shockwave when changing between Dragon Active to either the Fire Active or Ice Active. This shockwave deals a lot of damage rapidly.
  • Players can weaken this shockwave by dealing large amount of elemental damage to Alatreon.
• Alatreon can now control the Water element. However, this "water" is actually oil, and will ignite when hit with any of Alatreon's fire attacks.
• Alatreon can now throw ice spikes that clump and enlarge on the ground. If its lightning attacks strike an ice spike, the ice spike will glow red and explode shortly afterwards.
• All of its elemental attacks (save for its Dragon element attacks) seem to have a trace of dragon element, most notably its fire and lightning attacks.
• After slaying it, Monster Hunter Tri's victory music will play.
