Celosia Nanami

Celosia Karin Nanami is from Coumarine City in the Kalos region. She's a former member of Team Flare and is now a member of the Tekiyoku. She's a Grass Manipulator.

Present
Celosia was first seen in Episode 9 when she encountered the Mokusetsu in Anistar City, Kalos, alongside Dr. Zager and Mable. This is when the Mokusetsu was there to find Ikazuchi, which they recently had gotten already. She fought against Ash.

After Mable was sent into the river by Serena, Celosia was sent to go check on her. On her way, she found Bonnie, who had wandered on her own to try to get a closer look at the battle. Celosia took Bonnie away and kidnapped her, saying she's been "selected", similar to what happened with Serena when she was younger with the Science Division.

After the battle defeat, Celosia, unofficially working with the Science Division for now, and Dr. Zager brought Bonnie to one of Lysandre's old labs in Geosenge Town. They had left a note to tell the rest of the Mokusetsu to come there with Ikazuchi, and if they tried to fight, they would kill Bonnie. If they didn't show at all, they would use Bonnie for science. They locked Bonnie in a chamber in the lab.

From here, Celosia and Dr. Zager ran a few errands to get materials needed for experiments. They returned with an anesthetic vapor designed to put her in a deep sleep. Upon spraying it, nothing happened though, and they went for another errand. During this time, Bonnie had escaped on her own, which Celosia and Zager surely saw later.
