U-Killersaurus

'''

U-Killersaurus (Uキラーザウルス, U-Kirāzaurusu) is a powerful choju, probably among Yapool's strongest, it later evolves into U-Killersaurus Neo (Uキラーザウルス・ネオ, U-Kirāzaurusu Neo). It first appeared in the film, Ultraman Mebius & The Ultra Brothers.

First battle against the Ultra Crusaders
In the 1980s, the ever plotting Yapool sent a new choju of his, the U-Killersaurus, to dispose of the four Ultra Brothers; Ultraman, Seven, Jack and Ace. Their battle began on the moon, with the four Ultras dodging everything U-Killersaurus threw at them.

Grappling with the beast proved futile, as it's strength was enough to hold off two Ultras at once. When the four Ultra Crusaders tried to use their beams on the choju, it flew towards Earth. The heroes tried to stop U-Killersaurus, only to be met by a barrage of his organic missiles.

Avoiding those, the Bros. prepared to launch their beams again, when Ultraman halted them; firing their beams so close to the Earth could harm the citizens. After grappling with U-Killersaurus' extendable claws, it was then that the four of them did the only thing they could do: sealing U-Killersaurus with Yapool.

After crippling U-Killersaurus by blasting off his limbs, Jack and Ace combined their Specium and Metallium Rays to send U-Killersaurus plummeting into the Earth. Then using their Final Cross Shield, the four Ultras sealed U-Killersaurus and Yapool into the bay they had landed in.

For twenty years it would remain sealed, until Aliens from; Temperor, Zarab, Guts, and Nackle would try to free the creature.

Revival and Destruction
After being revived by Alien Nackle and Alien Guts, U-Killersaurus was even more powerful than before. Yapool was revived as well, and casually killed his supposed ally, Nackle (Guts was destroyed by Mebius). As far as he was concerned, Nackle was just a pawn. U-Killersaurus then proceeded to mercilessly beat the Ultra Bros. with his new strength.

Even when Ultraman Taro and Zoffy arrived to assist the brothers, they still could not stop this juggernaut of a monster. U-Killersaurus Neo soon caught Mebius with his large pincers, and prepared his ultimate attack in order to kill him. However, the remaing Ultra Bros. combined their power with Mebius, and the result was Ultraman Mebius Infinity Mode!

U-Killersaurus Neo was helpless against the new hybrid Ultra Warrior, as he easily smashed into his body, saving Aya Jinguji who was trapped in the colossal kaiju's body and came out the other side, causing U-Killersaurus Neo to decay into dust, along with Yapool.

Plasma Killersaurus Hunting

Baltan Battler Barel, Guts Gunner Garm, and Magma Master Magna were secretly went to a planet filled with lava and a surface just like our Moon to find and hunt Plasma Killersaurus. Shortly after discovering it hiding, the monster woke up. The trio then ran to avoid chunks of fallen stalagmite until they stopped, discussing how Killersaurus came to this planet and how to get the monster's Plasma Souls. When the creature fully awoken, the trio endured a sandstorm, that was followed by the monster's roar and leaped high to dodge an attack. After dodging the creature's lightning bolt attack, the trio decided to attack it. Garm decided to fire his Gatling Shots at the behemoth, but it protected itself with an energy shield. Barel then launched his Lightning Boomerang at the creature, but it absorbed it into his body. Magna then summoned his Lightning Claw to attack, but the monster launched a plasma ring to knock him out of the air. He tried again, but this time, he saw a vision of a new sword before dodging another of Killersaurus's attacks. When the creature fired his lighting again, Manga deflected it, but at the price of his own weapon. Magna then retreated and was joined by the others. Killersaurus fired another lighning weapon at them, but this time, Garm countered it with his Gatling Gun. Unfortunately, he too lost his weapon afterwards. Magna then summoned his inner power and charged straight at the beast resulting in a small explosion. He may have been knocked back, but, he gained a new sword in the process. After a few moments of discussion, Magna summoned the power of the weapon, lighting it up and striking a major part of Killersaurus's Plasma Souls, and soon after, it left, but not without Magna losing his new sword.
