|This article is about a/an ally chacter in Juken Sentai Gekiranger.|
Bae, originally a human, fought Mele while he was watching a giant battle during the time of the Fierce-Confrontation Rebellion, and ending up being eaten by her after he assumed his tiny, anthropomorphic fly form upon performing an imperfect version of the forbidden Gekiwaza in a vain attempt to take her down. However, the residual energy Rio used to bring Mele back to life had unintentionally resurrected Bae as well, but in order to prevent his body from decaying, he needs Mele's Rinki from her body.
As a result, Bae's life is dependent on Mele and being away from her for too long can prove fatal. He usually stays within her stomach, but when a battle between the GekiBeasts and a giant Beast-Men begins, he gets out by impulse and acts as a commentator for the battle, rooting for Beast-Fist Giant GekiTohja and Herculean Giant GekiFire, until it ends and Mele eats him again. He also acts as a sort of unwanted confidant for Mele, which aggravates her to no end, even though she keeps him around out of pride. As a Fierce Beast-Fist user, he is a well of knowledge when it comes to the Beast Arts, knowing the Kensei well and vice-versa.
Though the Kensei, except for Sha Fu and Sharkie, accused him as a traitor until the truth is revealed when Bae helped Gou Fukami to overcome his werewolf side even though he died as a result. However, Mele revived Bae due to the fact that Bae was resurrected by Rio, and therefore was part of her love for him. When Bae brought the Gekirangers to save her, Mele has a change of heart for Bae and treats him like an equal soon after. Furthermore, due to Mele's purging herself of Mythical Ki, what remained of it entered Bae, giving him a true life once again, making him no need to rely on Mele in the future.
After the final battle, Bae tags along with Gou as he sets off on on his own journey. They both say their farewells to Jan Kandou before heading off. Sha-Fu said that his motto is "There is training while speaking" (喋りの中に修行あり Shaberi no naka ni shugyō ari?). .
He was among villains captured within the Space Prison in Makuu Space in Kaizoku Sentai Gokaiger vs. Uchuu Keiji Gavan: The Movie and released by the pirate Sentai as they caused a big ruckus within.
These Gekiwaza are used by Bae and employ channeling Fierce Ki into his speaking and voice.
- Speak-Speak Soul (言言霊 Koto Koto Dama?): Bae uses his voice to force the target to perform a spiritual battle. Those who can also control Fierce Ki can see the projection of what the user sees.
- Bae shares the same voice actor with Tatsulot from Kamen Rider Kiva.
- His name is a play on the Japanese word for "fly" (蝿 hae?)
