Ash is a formling. (Dragon)

Time unknown, Tiger Widow Island

After a scuffle with a tiger widow and getting Krux, Acronix, and Wu out of there, Ash crash landed onto the shore, flinging the three men off her back. Wu approached her body.

"Ash, it's gonna be ok. Please get up." Ash didn't respond and that was when Wu noticed two marks, indicating that Ash was bitten. Krux walked over and saw the same thing.

"Oh my gosh. I'm sorry Wu."

"Why does it matter now? I've lost the most important person in my life." Wu got up and walked towards the shore where he just stood there. Krux did the same, but in another direction while Acronix witnessed the entire thing. He decided to kneel down and gently rub Ash's snout, careful to avoid the bite wound.

"I don't know you as well as my brother does, but I can tell that you were an important person in his life. Please come back, I hate seeing Krux and Wu like this." Acronix continued to rub her scales.

Ash was watching the entire thing while in limbo. The First Spinjitzu Master expelled the venom from Ash and the remaining dark magic that courses through the twin's veins.

Wu and Krux were still on the shore. Acronix was about to join them when he heard breathing. He turned to Ash and saw that her eyes were open, almost causing him a heart attack.

"You're alive. Did I wish for this?" Still a dragon, Ash let out a soft growl. "Brother, Wu, turn around. Ash is alive."

"This is nothing to joke about Acronix. There's no way anyone could survive after being bit by a tiger widow. Except for a Djinn." Wu replied, not turning around.

"And I thought Krux was stubborn." Ash then let out the loudest roar causing the two men to finally turn around. They had to do a double take before finally realizing that Ash was alive. They ran to hug her, but the reunion was cut short and the four were lost in time again.

Time unknown, First Realm

After getting away from Iron Baron, Wu, Faith, and the ninja were sitting around a fire. "So Sensei, if you came back, Ash and the time twins must have as well. Do you know where they are?" Kai asked. Wu sighed.

"I haven't felt their presence since we landed on Tiger Widow Island." The ninja were shocked.

"What happened?" Jay asked, scared of what he might hear.

"The twins and I were being attacked by the giant spider when Ash came to our rescue. We got away, but she died as a result of being bitten. While Krux and I had our backs turned, Acronix must have said something that my father heard, bringing Ash back to life. The reunion was cut short though as we're now in the present." The others were happy to hear that their sister was alive.

"But you don't know where they are though?" Jay asked again. Wu gave him a nod.

"I don't know who to thank." Cole told Wu.

"I believe that you guys should thank Acronix. Yes, my father was the one to expell the venom, but Acronix was the one that wished for Ash to come back to us. He could tell that her death hurt Krux and I and he doesn't like seeing others hurt or sad. And I do believe that both twins want to change as they were persuaded into betraying the alliance at the time." The ninja understood and everyone turned in for the night.

Ash and the twins arrived at the same time the ninja did. Together with everyone's help, they brought down Garmadon and his cult. As soon as Ash landed and the twins got off, Acronix was tackled into a group hug by Cole, Kai, Jay, and Zane.

"What the hell is this?" Acronix asked while glancing at Wu.

"I may have told them of what you did back on the island." Wu gave the twin a warm smile. He then felt a tap on his shoulder.

"What did he do exactly?" Morro asked. Wu explained to the others what Acronix did. Everyone then gathered together. Morro walked up to Acronix and held out his hand. The twins shook it.

"How can I ever repay you?"

"How about you set me up on a date with that cutie over there." Acronix replied, pointing at Cyrus. This caused the inventor to blush.

"Deal." Morro told him. Ash and Krux just rolled their eyes.

After the defeat of the Oni, everyone was able to finally live in peace with each other.

And about the part where Ash was in limbo, it was long and I shortened it. Also, The First Spinjitzu Master is able to give others a second chance at life and no one can tell me otherwise.
