Great Sword Man Zubaan

"Zubaan!"

Great Sword Man Zubaan (大剣人ズバーン, Daikenjin Zubān): Zubaan is actually the Precious called The Golden Sword that was enshrined in the ruins of Lemuria.

Boukenger
Zubaan was originally in Saken Mode (Sacred Sword Mode). When the seal of the Saken Mode is turned, Zubaan can transform into a human-sized fighter. He also has the ability to grow to the size of DaiBouken at will. Its special attack in combination with Ultimate DaiBouken is called Giant Holy Sword Slash (大聖剣斬り, Dai Seiken Giri)." In his humanoid form, Zubaan's speech is limited to saying his name, or mixed-up parts of it (such as "Ban-ban!", "Zun! Zubabababababa!", etc.) much like a Pokémon. In Task 42, he became the size of DaiBouken's sword, GoGoKen, to help the Boukengers defeat the Questers' Homunculus. Voyager DaiBouken with Zubaan in hand used the Super Riding Adventure Drive to do so. Zubaan is also able to finish giant monsters by using a powerful double kick or a rapid barrage of quick attacks. After Satoru Akashi and Sakura Nishihori left for space, Natsuki Mamiya carries Zubaan with her on the Boukengers' adventures.

Gokaiger
Zubaan fought in the Great Legend War, along with the first 34 Super Sentai teams. He, along with everyone else, sacrificed their powers to destroy the Zangyack armada. Zubaan's Ranger Key, along with those of the 9 other Extra Heroes, ended up in the hands of Basco ta Jolokia.

The copy of Zubaan was first summoned during Basco's attempt to gain the Greater Power of GoGo-V. Zubaan fought alongside Black Lion Rio and Confrontation Beast Chameleon-Fist against the Gokaigers, taking on Gai (GokaiSilver) who defeated Zubaan with Gold Mode. His key, however, was reclaimed by Sari along with Rio and Mele's before the Gokaigers could get them.

Basco united his nine remaining Extra Hero copies, his Black Knight key having been taking by Gai in his failed attempt to gain the greater power of Gingaman, when he was confronted by Gorou Hoshino (OhRed†). The Extra Heroes would then fight the Gokaigers again, who wished to take the Ohranger's greater power rather than just be given it. Zubaan joined with Wolzard Fire against Gai who fought them as the Go-on Wings hybrid, defeating them with Gold Mode's Gokai Legend Crash. They enlarged and fought against him in GoZyuJin, but soon fell for a second time and Zubaan's key, along with the rest of the Extra Heroes was claimed by Gai.

When the Gokaigers first transformed into Extra Heroes, in their fight against the Dogormin, Luka (GokaiYellow) became Zubaan. She taunted the Dogormin by imitating Zubaan's catchphrases.
