Berukyurosu

The Berukyurosu is a new thunder element wyvern exclusive to Monster Hunter Frontier. It will debut in the upcoming 4.0 update in MHFO. Many suspect that this wyvern, along with Espinas and Akura Vashimu will make an appearance in the upcoming game Monster Hunter 3. It will appear in the new area, Desert Canyons. Berukyurosu is able to shoot a sweeping, linear lightning beam from it's mouth, while hovering in the air. The beam itself is very similar to that of the Rajang. Berukyurosu is highly adept in aerial combat, able to do even more difficult maneuvers than the Kushala Daora. Capcom has said the AI of Berukyurosu has been upgraded and is far different from all other monster AI in the MH series. It has the ability to learn patterns of attack from hunters and will counter it, or will attack/evade accordingly.

Its most dangerous attack is its Electrical Sky Slam, where by it will fly high and suddenly strike down (like the Rathalos). However, there will be thunder over a huge radius around where it lands. This attack has one of the widest ranges in the game; get hit by it and you are as good as gone.
