Kaldea Orchid

Kaldea Orchid is a character from The Bouncer. Kaldea Orchid is an old friend and romantic interest of Sion Barzahd. The Mikado Group faked her death and used her as a subject in their bionoid experiments, which Dauragon hoped would provide him with valuable information. As a result, Kaldea gained the ability to shift between her human form and the form of a black panther at will. She fought Sion, Volt, and Kou alongside Dauragon in her panther form, and later tried to stop them from reaching the satellite control room on the Galeos. Depending on who the player uses to fight Kaldea, she will either die in Sion's arms or be killed by Dauragon after this fight.

The Bouncer trilogy
She was seen as a blank panther stalking the group until they got to the Mikado building. By then, Ayame met the bouncers, and she played a massive piano triggering something from Sion's past, specifically her so-called death. Then she turned into her panther form as Dauragon challenged the group. She was unable to defeat them; however, Dauragon separated the trio while Ayame retreated.

Later on, as Sion and Ayame infiltrated the headquarters and he found a tad of info about how Dauragon experiments on humans for his bionoid technology projects. They soon saw her twice for a short while, the latter being a battle between them. Upon her decond defeat, she changed into her human form, though Sion never recognized her. She changed back and unlocked the chamber holding Dominique, where Mugetsu was waiting.

By the time the team, Goten, and Trunks reached the Galeos, she was encountered one last time. She lost again, then Sion put two and two together as she said she's older than him; she unveiled that Mikado faked her death and used her as an experiment in order to make Dominique more human. Aside from those twisted experiments, she pitys Dauragon because of his loneliness. Unfortunaely, she was killed in point blank range as he wants no sympathy from her. Her body was left behind as the group retrieved the Dragon Ball and Dominique, defeated Mikado and escaped before the Galeos crashed into the satellite.

She was later seen several months later, encouraging Sion to keep living for Dominique as he's been fighting his inner demons as well as his own doppelganger.
