This is a new Ultraman and Supergirl crossover during S3 just as Supergirl is put into a coma. An Ultra arrives to help, can he stop Reign?

I don't own Toei, Tokusatsu, DC, CW or any of these characters. Enjoy!

National City:

In the DEO, everyone was panicking as the evil Kryptonian known as Reign had just put Supergirl into a coma. Everyone was working on a way to wake her up but nothing was working which was making Alex Danvers panic!

"What do we do?" Alex was sat next to her comatosed sister as she was crying until she felt a hand on her shoulder: it was her boss and friend, J'onn J'onzz. "J'onn, is there a way to wake up my sister?" Alex begged but J'onn shook his head then hugged her.

"Alex, be strong. Kara needs us and while Reign is still out there, I've called in some help." J'onn told her and just as Alex was about to speak, a white blur flew into the DEO and landed behind J'onn.

"It's been a long time, J'onn." The white glowing figure spoke as the glows faded away: the figure was humanoid with a silver body with red and black markings. On the chest was a blue ring and his eyes were white with the head of the figure was almost metallic. "Introductions. I'm Gai, Ultraman Orb." Gai spoke as he reverted to human; he was wearing blue trousers, black boots, a black t-shirt and a black leather jacket.

"Agent Danvers and this is Supergirl." Alex told them and Gai nodded. Gai then turned and walked over to Supergirl, he took a card out of his pocket and placed it in Supergirl's hands. "What are you doing?" Alex asked then J'onn placed a hand on her shoulder, the card then started glowing.

"Gai is using his power to heal her," J'onn told Alex then they saw that the card was glowing brighter. "The card contains Ultraman power: a unique power that can do anything." The monitor's then started flashing: Reign was back!

"Get Kara into the Recuperating Pod! I'll handle Reign!" Gai told them and J'onn nodded while Alex was confused. "Pair of glasses is the worst disguise ever." Gai told them then he ran off to where Reign was attacking while J'onn and Alex got Kara to the Legion Ship.

L-Corp:

Reign was floating in front of Lena's office as was about to strike when a blue orb hit the evil Kryptonian, she crashed into a truck outside the building then she saw a man walking towards her.

"Seems like you're the one I'll be fighting." The man spoke as he took off his hat; it was Gai. "Now, let me show what I can do." Gai pulled out the Orb Ring and it flashed a white and blue light. "Ultraman! Ultraman Tiga! I'm borrowing the power of your lights!" Gai shouted as inserted two cards through the ring then pressed a red button on the handle.

"Ultraman! Ultraman Tiga! Fusion Up! Ultraman Orb: Spacium Zeperion!" Gai had transformed into a silver, black, red and purple form of Orb with gold shoulder pads and a purple crystal on the forehead.

"You won't stop me! I already took down Supergirl!" Reign shouted then the two charged towards each other and started fighting. Mon-El and Irma arrived to fight Reign but were surprised to see that the dark Kryptonian was losing to Orb, they watched as the purple markings on Orb flashed then he was moving so fast that Reign couldn't see his attacks.

"Still think I won't defeat you!" Orb shouted as he kept attacking Reign, she got so angry that she punched the ground which sent a shockwave and hit Orb. "Lucky shot. Now, it's my turn!" Orb shouted as he jumped back up and started glowing red then was engulfed by flames.

"Ultraman Taro! Ultraman Mebius! Fusion Up!" Reign flew towards the burning Orb but the flames sent her flying into a petrol tanker. "Ultraman Orb: Burnmite!" The fire shattered like glass to reveal Orb in an all red form with silver and gold markings along with two huge horns on his head and a yellow crystal on his forehead.

"Time for me to turn up the heat!" Orb shouted as he charged towards Reign who had got back up on her feet. The pair were fighting hard then Mon-El and Irma joined the fight but Reign took them down with no problem. "Leave this to me." Orb told them then he kicked Reign far then crossed his arms over his chest. "Stobium Dynamite!" Orb shouted as he began engulfed in flames, he then charged towards Reign and grabbed her as his flames became more hotter until the pair blew up and sending Reign flying high into the sky.

"Where is he?" Irma asked as she and Mon-El looked around for Orb until they saw the fireballs around them flying towards one spot and turned into Orb's Burnmite form but he was kneeling down in pain.

"That one does hurt like hell but let's hope that's brought us time." Orb spoke as he slowly got up onto both feet. "Next time, leave it to me." Orb told both Mon-El and Irma as he changed into his Spacium Zeperion form, he then flew off towards the DEO with Mon-El and Irma following close behind.

Legion Ship:

Alex and J'onn were on the Legion Ship with Brainiac Five trying to find a way to wake Kara up. Kara still had the card that Gai had placed in her hand and it was still glowing which gave Alex some hope that her sister would wake up. They heard footsteps coming towards them and it was Orb, Mon-El and Irma as they ran towards the Recuperating Pod to see that Kara was still unconscious then Orb stepped forward.

"Gai, what card did you put in Kara's hand?" J'onn asked then Orb turned around and looked at his old friend.

"Ultraman Cosmos. An Ultraman who has the power of healing and it's slowly healing all of Kara's wounds." Orb explained then he turned and looked at Supergirl who hadn't woken up still. "Alex, do you trust me?" Orb asked as he looked at Alex who nodded then like magic, Orb had turned into purple and red atoms and disappeared but what they didn't know was that Gai had entered Kara's subconscious.

Kara's subconscious:

Kara was sitting on her couch as she was confused about what was going on. She was about to lay back when she heard the door knock so Kara walked over to it and opened it to reveal a man in blue jeans, black boots and a black t-shirt.

"Can I help you?" Kara asked and the man nodded then he walked into Kara's apartment. "Who are you and what do you want?" Kara asked while the man looked around.

"Gai. Gai Kurenai. I'm an old friend of J'onn and he asked me to help you." Gai introduced himself as he looked out the windows. "Your friends wanted me to come here and see if I can wake you up. Your brain is not damaged from your fight with Reign with a good thing, considering you're in a coma." Gai told Kara who looked confused about everything that was going on.

"Wait! Go back! Did you say a coma?" Kara asked and Gai nodded as he walked over to Kara as he picked up her glasses.

"You've been in a coma for two days." Gai told her which made Kara look around as she was more confused than ever. "You may think you're in your loft but this is where your subconscious feels more comfortable." Gai explained as he sat down on a stool by the kitchen side.

"If I'm in a coma, how are you here?" Kara asked then Gai pointed at Kara's cargian pocket, she reached inside it and pulled out a card with an image of Ultraman Cosmos on it.

"I used my Ultraman power to enter here and try to help." Gai explained as he showed Kara the Orb Ring. "Ultraman Orb. J'onn and I have a history but you can know more when we get you out into the real world." Gai explained as he stood up and looked around for a possible exit for Kara. "While I'm using my power to talk to you, the Legion are using their tech to keep you alive. Without it, you'll die." Gai explained as he sat opposite Kara who was on her couch.

"How do I get out of here?" Kara asked as she looked up at Gai who was smiling. "Why are you smiling?" Kara asked as she was confused about why Gai was smiling.

"When I first became Orb, I used to think that it was my powers as an Ultraman that made me strong, but I was wrong." Gai explained, he reached inside his pocket and showed Kara a photo of him and his friends from his past. "What made me strong was my abilities as a human. Supergirl has had an amazing life but by looking at the people in your life, I think Kara Danvers has had an amazing life too." Gai told her then something came to Kara, she got up and put on her glasses then walked towards the door with a key in her hand. "See you on the other side, Kara Danvers." Gai smiled and waved as he disappeared in a white light, Kara waved back as she put the key into the door and unlocked it.

"Here goes nothing." Kara spoke then she took a deep breath and walked through the doorway into a bright white portal.

Legion Ship:

Alex was sat by Kara's bedside as rainbow coloured particles exited the Ultraman Cosmos card and landed beside Alex: it was Orb in his Spacium Zeperion form. Alex then looked at Kara to see her sister's eyes slowly opening, it made Alex feel so happy that she jumped out of the chair as Orb changed back into Gai.

"Oh my god! Kara?" Alex asked as she stood over her sister as Kara looked up at her sister. "Are you okay?" Alex asked and Kara slowly nodded, the two sisters then turned and looked at Gai who was smiling. "Thank you for helping my sister." Alex thanked and Gai nodded then Kara sat up and held out her hand with the Ultraman Cosmos card.

"Thank you, Gai." Kara thanked and Gai nodded, he then sat down and smiled at the sisters. "Are you staying or leaving now?" Kara asked as Gai put the Cosmos card inside his card holder on his belt.

"I'll stick around and help you with Reign," Gai answered then he chuckled as he sat forward. "Anyway, I did say I would tell you how I know J'onn." Gai smiled, he got up and held his hand out. "I look forward to looking with you, Supergirl." Kara smiled and nodded as she took Gai's hand and shook.

"I look forward to seeing you fight, Ultraman Orb." Kara chuckled so Gai and Alex then helped Kara out of the bed and towards the bridge where everyone was waiting.

I hoped that you enjoyed the first chapter of my new Ultraman and Supergirl story. I did have Ginga and Victory planned but then I decided to use Orb because while I became a fan thanks to Ginga, Orb was favourite and his forms are amazing!

What did you think of the first chapter? How did Gai and J'onn meet? Next time, Orb and Supergirl VS Reign! Ciao for now!
