It mainly inhabits the Highland and Desert areas and is capable of using the Thunder Element and the Fire Element. It has also been spotted at the Great Forest Peak.Kuarusepusu has the amazing ability to collect and focus sunbeams and electricity as a weapon. Kuarusepusu is well known for its incredible attack strength for whatever rank its hunted in much like Gurenzeburu who appears to be its rival in the Highland's.Many of its attacks are a combination and improvement of Agnaktor's and Lagiacrus with some very heavy attack power and range added. For example when Kuarusepusu does a slither attack its range is unlimited and it will not stop until it hits its target or passes it. The same goes for its digging attacks. When Kuarusepusu charges its thunder during a storm the following burst will be surprisingly wide in range compared to Lagiacrus on land catching many Leviathan hunters off guard paralyzing them or instantly killing them. If Kuarusepusu charges during the sun shining bright it will make a flash much like Gypceros blinding hunters.A unique feature from Kuarusepusu is that it can leave crystals on the ground from tail attacks and shake them off. When the sun shines on them, stepping close will cause them to shine and then explode causing KO. But if you attack them you gain fire element on your weapon along with whatever element your weapon has at the same time for 1 powered hit. During a Storm stand near them and they will glow blue then explode with electricity. But just like before attack them and gain their element which is Thunder. On a side note Kuarusepusu can activate all the crystals exploding them at once when it roars. When the crystals have been left alone long enough they will explode anyway by themselves.In the Great Forest Peak Kuarusepusu is super charged with electricity making all its attacks hit even more amazingly hard and its slither is extremely deadly homing in on hunters covered in electricity instantly killing hunters or using its even more improved thunder charge with fearful range.In the Desert Kuarusepusu can be found in pairs appearing to communicate by flashing their crystals as this is only seen during the quest with a pair. In a pair they perform a team based attack that requires a partner. They both signal each other by curling and flashing and when they both perform the same light show they begin to charge up and their crystals begin to flash red and they spread sparkles that glow in the air followed by a sun burst so huge anyone within the range of double the Kuarusepusu's body will be burnt with extreme fire damage and out of range hunters get blinded causing KO.
