Go-On Blue

"Just Correct!! Go-On Blue!"

―Go-On Blue's roll call^[src]

Renn Kosaka (香坂 連, Kōsaka Ren) is Go-On Blue (ゴーオンブルー, Gōon Burū) of the Go-Ongers. Nicknamed the "Cyclopedia" for his attention to the smallest detail, is a former bus driver who tends to be somewhat talkative.

History

Go-Onger

Because of his doting personality and cooking expertise, he has been referred to as the Go-Ongers' "mother" (オカン, okan) by the other Go-Ongers and even his own Engine partner, Engine Buson; he takes no offense to and even revels in the reference. The son of a family that runs a beach-side inn, Renn, as a young boy, prayed and offered omelets every day to a guardian statue in the eventually futile hope that his sickly mother would recover. The guardian statue turned out to be the sealed form of the Arelunbra Uzumaquixote, which Renn learned only after Air Pollution Minister Kitaneidas and Water Pollution Minister Kegalesia tried to claim it. Renn carries a small memo notebook, which is the source of his massive knowledge; in it, he jots down notes about and draws doodles of the enemies the team faces, even in the middle of a fight. Not only is Renn the "mother" of the team, but he is also the chief technician; he made modifications to the Engines so they could come together in the Engine-O G6 and Engine-O G9 formations, developed the Supply Soul and the Double Engine Soul Kankanbar, and assisted the Go-on Wings in fine-tuning the Armored Wheel GoRoader GT. After the final battle, Renn becomes Sosuke Esumi's mechanic in the go-kart racing circuit.

As Go-on Blue, Renn's physical strength is magnified. After transforming into Go-on Blue, Renn says, "Just Correct!! Go-on Blue" (ズバリ正解！！ゴーオンブルー, Zubari Seikai!! Gōon Burū). With the Mantan Gun in Rod Mode, he can perform the Go-on Drift (ゴーオンドリフト, Gōon Dorifuto). With the Mantan Gun in Gun Mode he can perform the Sniper Shoot (スナイパーシュート, Sunaipā Shūto). With the Garage Launcher (ガレージランチャー, Garēji Ranchā) he can perform Launcher Starter (ランチャースターター, Ranchā Sutātā) and Jumping Attack (ジャンピングアタック, Janpingu Atakku).

Go-Onger vs. Gekiranger

Encountering the Gekirangers, the Go-Ongers lose the Engine Souls to the Gaiark and Meka. With Retsu Fukami and Gou Fukami's help Renn and Hant manage to gain Geki. With Engine-Ken, a new type of Geki fighting fist, Renn was able to access his beast spirit (which turned out to be Buson). With this he performs On On Dan, where Bus-on, apart of his Engine Soul attacks, as a manifestation of will. MOVIE STORY-Engine Sentai Go-Onger vs. Gekiranger

Shinkenger vs. Go-Onger

After a difficult fight against Pollution President Batcheed, Renn and Gunpei were transported to the Samurai World where they encountered Chiaki Tani and Kotoha Hanaori of the Shinkengers. MOVIE STORY-Samurai Sentai Shinkenger vs. Go-Onger: GinmakuBang!!

Gokaiger

Legend War

A few years later, Renn fought alongside not only his own team, but every single Sentai Ranger in existence, against the Empire of Zangyack when it attacked the Earth in the Great Legend War. After fighting against hundreds of Gormin and their Sugormin commanders, Akarenger noticed the fleet moving towards them. He gathered all the Rangers together and gave them the order to sacrifice their powers to wipe out the first invasion's armada. The Go-On Blue powers are later used by Joe Gibken via the Ranger Keys.

Farewell Space Pirates

After the defeat of Ackdos Gill, the Gokaiger returned all the Ranger Keys to the former Sentai heroes. Renn and his team have their powers again. TV STORY-Final Ep.: Farewell Space Pirates

Akibaranger

Super Hero Taisen

The Go-Ongers, alongside the Gekirangers, Gorengers (bar Akarenger), Goseigers, and Shinkengers, emerge through a dimensional wall.

Renn, alongside his team (the Go-On Wings were absent), among the majority of the Super Sentai heroes, was caught up in the "Super Hero Taisen" incident which eventually resulted in the Super Sentai teams and Kamen Riders joining forces to defeat both Dai-Zangyack and Dai-Shocker.

Zyuohger vs. Ninninger

The first 38 Sentai projected into Wild Tousai Shuriken King.

Go-On Blue appeared with his team among the first 38 Super Sentai whom collectively empowered Wild Tousai Shuriken King in its fight against the titanic Gillmarda, granting the Ninningers and Zyuohgers the power to perform the Zyuoh Ninnin Super Sentai Burst which destroyed Gillmarda with the combined power of all 40 Super Sentai.

Super Sentai Strongest Battle

Battle1: Who is the Strongest in History!?

Renn joined the Super Sentai Strongest Battle as a member of Gunman Team, where he won the first round after fighting Gosei Pink of Pink Warrior Team. It’s unknown whether he participated in any of the other matches, but his team was eliminated either after losing the second round against the Brain Team or the third round against the Swordsman Team.

Personality

Renn is the most intelligent member of the team, being nicknamed Encyclopedia for his vast knowledge on different subjects, because of this, he takes notes of everything he learns. He will sometimes draw doodles of his enemy's faces even in the middle of the battle. Renn has a very warm and loving personality coupled with the fact that he is a great cook which earned him the nickname "mother" by the rest of the team, something he does not take offense no.

Etymology

Legend Sentai Devices

• Ranger Key
• Avataro Gear

The Go-On Blue Ranger Key.

"Go-Onger!"

―Mobilates' Gokai Change announcement^[src]

The Go-On Blue Ranger Key (ゴーオンブルーレンジャーキー, Gōon Burū Renjā Kī) is Renn Kosaka's personal Ranger Key and what became of his powers after he along with the rest of the 34 Super Sentai sacrificed their powers to end the Great Legend War.

This key along with the majority of the Ranger Keys were collected by the Red Pirates and later used by the Gokaigers. The Go-On Blue Ranger Key was mainly used by Joe Gibken (Gokai Blue), who used it to fight as Go-On Blue.

• When the Gokaigers became the Go-Ongers while fighting against Gormin while Marvelous was absent. TV STORY-Ep. 5: Judgement Pirates
• When the Gokaigers became the Go-Ongers while fighting a Zangyack force led by Insarn and Barizorg. MOVIE STORY-Gokaiger Goseiger Super Sentai 199 Hero Great Battle
• When the Gokaigers became the Go-Ongers while fighting Action Commander Uorlian. TV STORY-Ep. 19: Armor of the 15 Warriors
• When the Gokaigers became the Go-Ongers in their fight with Pollution President Babatcheed. TV STORY-Ep. 36: Partner Pirate
• As part of an all-lion Gokai Change which served as a demonstration to Ninjaman of the Gokaiger's powers. TV STORY-Ep. 45: The Confused Ninja
• As part of a bombardment of changes in the final battle with Emperor Ackdos Gill. TV STORY-Final Ep.: Farewell Space Pirates

After Zangyack were finally defeated, the Gokaigers gave the Ranger Keys back to their rightful owners. It is presumed that Renn received his key and became Go-On Blue once more.
