Birdon's History
Birdon (バードン, Bādon) is a bird-like Kaiju that debuted in Ultraman Taro. Alongside Tyrant, Birdon is considered the most memorable monster from Ultraman Taro as a result of the original's fearsome abilities, as well as the fact that he successfully killed not only Taro himself, but also Zoffy. As a result, numerous individuals of Birdon's species have appeared throughout the series, and usually pose a significant threat towards the Ultra they face in battle.
Sealed away in a volcano for centuries, two massive eruptions took place. One awoken the insectoid monster Kemjila and another awoke Birdon, a large prehistoric bird. After being released, Birdon took off in search of food, which instinctively was Kemjila. It then began attacking nearby buildings in search of food, marking the city as his own territory. Then Birdon noticed a fight between Ultraman Taro and a full-grown Kemjila.
Although Birdon and Kemjila were instinctive rivals and share and predator/prey relation, Birdon saw Ultraman Taro as a threat to his "territory" and attacked him instead, stabbing the Ultra repeatedly all over his body with his sharp beak until he died of his injuries. With Taro dead but inedible to the massive bird, Birdon turned his attention back to Kemjila, attempting to escape. Birdon attacked Kemjila and the two monsters resumed their fight, with the giant bird swiftly overpowering the insect before killing it with its beak and proceeding to tear its body to pieces and eating them. Upon finishing, Birdon took off to return to its volcanic nest, leaving the city devastated over Ultraman Taro's death. However, the Ultra's body was rescued and returned to M78 for resurrection.
Several days passed and as Birdon had consumed most of the Kemjila inside the volcano, it decided to feed on the humans who entered his territory. The situation became even more dire when a toxic sulfuric mist was seeping out from Birdon's volcano, posing a threat to Japan. ZAT hatched a plan to disable Birdon's deadly beak, using one of their aircraft to douse Birdon in glue holding him in place with ZAT proceeding to attack him. Birdon began thrashing around, ripping off patches of its own skin as it tore off the glue, making its eyes water in pain. With Birdon free from the glue, the monster began to attack ZAT.
Another Ultraman, Zoffy suddenly arrived to fight Birdon to avenge Taro. However, despite Zoffy's experience, Birdon fought back, lighting the Ultra’s head on fire with its flames. Zoffy tried to fight back, but was stabbed in the arm, then multiple times in his spine until he eventually succumbed to his injuries. Tired from the fighting, Birdon returned to the volcano, this time leaving Zoffy’s dead body in his wake. Now with Zoffy and Taro both dead, Birdon resumed its diet of humans.
Birdon soon attacked another city in search of food, attacking an apartment building where one of Kotaro's friends was recovering from when Kemjila attacked. ZAT arrived to stop Birdon, only for their weapons to annoy it into using its flames. Then Ultraman Taro, now revived by Mother of Ultra arrived on the scene and relentlessly attacked a shocked and wide-open Birdon. Birdon tried to fight back with its beak, but Taro avoided its attacks and then used a new weapon, the King Bracelet to electrocute the giant bird repeatedly. However just as it seemed Taro was about to win, he ultimately was forced to let go of Birdon in order to rescue his friend from the Kaiju's earlier attack, allowing him to escape. ZAT would suddenly discover eggs in the volcano, which could potentially cause more Birdons to spread.
As ZAT attacked the nest, Birdon returned to defend it, downing their jets. Ultraman Taro appeared once again and attacked Birdon. Using the King Bracelet as a muzzle, Taro disabled Birdon’s main weapons, but it was not enough to stop it yet as it continued fighting. Taro then thinks of a plan where upon recalling the King Bracelet, he lead Birdon back towards the volcano and then performed the Taro Split. Birdon became confused, crashing into the volcano and he fell deep into its recesses as another eruption sealed it back inside his prison and destroying his eggs. With Birdon gone for good, Zoffy's body was recovered and taken back to Nebula M78 to be revived as well.
A Birdon would then reappear in Ultraman Mebius. As GUYS was investigating a normally inactive volcano, Birdon emerged from the ground, beckoning its return. Birdon soon met Ultraman Mebius and used its immense power to beat down Mebius and then injected the Ultra with a strong venom with his beak. Weakened, Mebius was forced back into his human form as Birdon took off into the sky. Birdon was later spotted flying over the sea and GUYS tried to intercept it. Birdon was downed on the mainland as GUYS continued attacking, but this only angered Birdon into using its flames. Ultraman Mebius returned to save GUYS from the fire, but he was still weak as the venom had not completely wore off. Teaming up with GUYS, Mebius was able to overcome Birdon's strength and it was finally destroyed by both Mebius's Mebium Shoot and a barrier built by GUYS to contain the venom.
Sometime later, GUYS was chosen to test out new arrivals of Capsule Monsters. One suggestion was Birdon but this was turned down due to his poison sacks being an environmental threat.
Another Birdon would appear in Ultra Galaxy Mega Monster Battle: Never Ending Odyssey. In this series, Birdon is used by an Alien Reflect to fight Rei and his Gomora. However, the battle was short as Birdon continued to use hurricane winds and his beak to stab Gomora. Eventually, Birdon was destroyed when Gomora caught him by his beak and struck pointblank at his head with the Ultra Oscillation Wave.
In Ultraman Ginga S, Birdon was originally a part of Alien Chibull Exceller's Spark Doll collection. Birdon was given to Alien Guts Vorst shortly after Dark Lugiel was beginning to revive. Lived by Vorst, he landed on Earth and started blowing the countryside away with his hurricane winds. Sho then Ultlived into Ultraman Victory to stop him, but Birdon immediately battered him with his hurricane winds and kept trying to peck him but to no avail. Eventually, Birdon poisoned Victory after he got the Ultra down on the ground. But, suddenly, Arisa Sugita and a couple of elite UPG members attacked him with new weapons. Despite the poison slowing him down, Victory decided to UITrans his right arm into King Joe Launcher and fired it at Birdon's sacs, leaking out the poison in the process. Victory eventually defeated and destroyed him with the Victorium Shoot.
In Ultraman X, Birdon is known by Xio members for being one of the most dangerous monsters, having the ability to create dangerous venom. One of them emerged from Okumayama, a pregnant Birdon, who wanted to lay eggs and built a nest by collecting several buildings and electric towers, unintentionally placing several civilians in captivity. Xio was deployed to lure Birdon out of the nest, but once the Sky Musketty shot down, Daichi transformed into Ultraman X and rescued the jet. The Ultra attacked Birdon but soon succumbed to the poison's effect. It wasn't until Dr. Gourman developed the Cyber Armor system, allowing Cyber Gomora to combine with X into Gomora Armor. Using it, X managed to turn the tables in the fight and defeated Birdon with the Gomora Oscillation Wave. She was sealed inside her Spark Doll and Daichi assured that she was currently in peace with her eggs.
