After that, Kotaro joined the battle as a ZAT member and utilized Taro's power to fight against giant monsters while receiving assistance from either his fellow brothers-in-arms (Ultra Brothers) or his parents.

In the final episode, Kotaro severed his connection to Taro and returned the Ultra Badge, as he wanted to continue living his life as a normal human.

[1] His figure is based on the body of Ultraseven, with the latter's Beam Lamp,[definition needed] red color, and large projections.

Satake asked the producer, Kumagai, for a 170 cm tall suit actor for Taro due to the Ultra's head design.

However, in-universe, it is said that this was given by the Father of Ultra, as it meant "someone who has courage and loves justice" (勇気を持ち正義を愛する者, Yūki o mochi seigi o aisuru mono), which is similarly translated in Earth's culture.

[11] In original planning, Taro and his home series were meant to be named as Ultraman Jack (ウルトラマンジャック, Urutoraman Jakku), which was ultimately revised due to the aircraft hijacking incidents at the time.

After his first battle, Taro faces monster and alien attacks with the help of ZAT members and the Ultra Brothers' occasional appearances.

The Temperor was defeated by Taro's Neo Strium Ray while his leader is eliminated by the combined attacks from the Ultra Brothers.

There are also certain succeeding series that deviate from Ultraman's original statistics:[3][41] As the official website of Tsuburaya Productions stated: "The mature biological son of Mother and Father of Ultra comes from Nebula M78 of the Land of Light to Earth.

"[3] Kotaro transforms by using the Ultra Badge (ウルトラバッジ, Urutora Bajji), which was stored on the left shoulder of his ZAT uniform when not in use.

[46] Kotaro pulls the Badge and spreads his arms before drawing the item in the same position as his face and lifts it towards the sky, shouting "Taro!".

[41] Ultraman Taro is said to be the strongest Ultra Brothers at the time of his debut on Earth, evidenced by the fact that his Color Timer usually only blinks at the end of the battles and he is capable of surviving even after being stabbed by Depparas' tusk in the gut.

[56] His strongest attack is the suicidal Ultra Dynamite (ウルトラダイナマイト, Urutora Dainamaito), as he charges his body with fire and runs towards the opponent.

[54][57] It is once used against Alien Katan as his body reconstituted due to his Ultra Heart (ウルトラ心臓, Urutora Shinzō)[58] As a result of its dangerous nature, Taro sealed it until he is forced to use it again in Ultraman Mebius during a failed attempt to destroy Inpelaizer.

After saving the ship's crew from Oil Drinker, Kotaro plants the seed which grows into Tigris Flower which becomes the space monster Astromons.

His body is brought to the Land of Light and bestowed with the spirit of Ultra to become Ultraman Taro, taking down Astromons moments after the fight.

In the final episode, Kiyoshi Shiratori loses his life by Samekujira, a space monster commanded by the invader Alien Valky.

Ultraman Taro manages to defeat the monster and Kotaro severs his bonds to preserve his humanity, throwing the Ultra Badge to the sky.

[63] After auditioning for the role, he was first given a guest role Ichirō Shinoda (篠田 一郎, Shinoda Ichirō) in episode 20 of Ultraman Ace by producer Yōji Hashimoto (橋本 洋二, Hashimoto Yōji), who after seeing Saburo's suitability as a main character, decided to get a first impression on the actor at the filming site.

[79] While visiting the set of Ultraman Ace, he was impressed with Keiji Takamine's character (Seiji Hokuto) wearing a scarf and decided to do the same during his filming as well.

[80] Shinoda usually commutes to the filming studio by train and one time he woke up and found himself surrounded by children who were fans of Taro.

While reading the script for his character, Shinoda portrayed Kotaro as a child when facing against monster attacks believing that the childhood nature is suitable for Taro.

[85] Shinoda maintained a good relationship with the late Peggy Hayama, who voiced the Mother of Ultra and her human form, Lady in Green.

[90] Additionally, Taiyo Sugiura and Saburō Shinoda starred in a late night drama named The Last Dinner (最後の晩ごはん, Saigo no Ban Gohan), where co-star Yūichi Nakamura expressed his delight to act alongside major Ultra Series actors.

Based on Oricon's list, Ultraman Taro ranked the third place in all three categories: total, men and women alike.
