#u-killersaurus

U-Killersaurus is a powerful Terrible-Monster, probably among Yapool's strongest, it later evolves into U-Killersaurus Neo Uキラーザウルス・ネオ. At the beginning of the movie, U-Killersaurus is seen fighting against the Ultra Brothers; Ace, Ultraman, Ultraseven, and Jack on the Moon. However, U-Killersaurus is able to overpower the four Ultra Brothers with its strength. When the Ultra Brothers combined their beams into one, U-Killersaurus takes flight and dodges their combination beam and flys towards the Earth. While fighting on space, as the Ultras tried to use their Ultra Beams, Ultraman warned them if it misses, it will directly hit Earth. As a result, U-Killersaurus took the chance and grab the Ultras with his tentacles until Ultraman uses his Ultra-Slash to free them. After Ultraman and Seven weakened the Terrible-Monster, Ace and Jack blast it down towards the sea of Earth with their Metalium Beam and Spacium Beam respectively. The four Ultra Brothers then sealed Yapool and U-Killersaurus with their Final Cross Shield. Twenty years later, the seal of U-Killersaurus become undone thanks to Alien Guts and Alien Nackle. Yapool revived as well, later U-Killersaurus killed Alien Nackle, which is supposedly their ally but Yapool revealed they are nothing than just pawns. The Terrible-Monster then proceeds to evolve into U-Killersaurus Neo and overpowers the Ultra Brothers and Mebius. Until Taro and Zoffy arrival to restore the energies of the Ultras, they managed to fight on par with the Terrible-Monster by using their beams and slash attacks. When Mebius about to use his Mebium Shoot, Yapool shows that he kept Aya prisoner within U-Killersaurus's forehead in an unconscious state, and then blasted the latter with his Killer Eye Ray and holding Mebius on the ground with mandibles and prepares to use his ultimate attack on Mebius. Though suceeded in using his ultimate attack, the Ultra Brothers then fuses with Mebius and transforms into Mebius Infinity. U-Killersaurus Neo then crumbled to dust after Mebius Infinity uses his Cosmos Miracle Attack and dashing into his body and saving Aya.
