After Shao Kahn's failed invasion of Earthrealm Sektor's programming had been corrupted. He deemed his father the grandmaster weak and unfit to lead the Lin Kuei, so he killed him. Sektor transformed the entire Lin Kuei into cyborgs except one had escaped his grasp Kuai Liang. This came back to bite him when Kuai Liang was able to claim the dragon medallion before he could. Sektor was furious, but not deterred, so he founded his clan of cyborg ninjas the Tekunin.

Sektor and his clan of cyborgs were on a mission in Outworld. When they were all transported to this place called the boiling isles. Sektor was separated from his clan, but using their devices they regrouped. Sektor throughout his adventures in this unfamiliar place had encountered many people. He got back his old Right-Hand Cyrax and allied himself with Quan Chi, a debt he would soon need to pay on.

"Grandmaster Sektor Cyrax's reprogramming is almost complete," A cyborg said.

"That is good don't make any mistakes I don't want him breaking free again," Sektor said.

"I see you are already making use of my new gift," Quan Chi said while coming through a portal.

"Quan Chi the tekunin is at your service," Sektor said.

"I need your help we have a situation all of my enemies have met up at a certain location," Quan Chi.

"What do you want me to do about that?" Sektor asked.

"I know your clan has a lot of power, storm the place and kill everyone inside," Quan Chi said.

"Is Liu Kang there?" Sektor asked.

"Yes," Quan Chi answered.

"My clan won't be able to do anything, one of their allies from this realm. Edric and Emira Blight have these electricity powers that disable us," Sektor said.

"I know someone who can get around that," Quan Chi said. Quan Chi took the entire Tekunin to Shang Tsung. Shang Tsung used his sorcery to enchant all the cyborgs into being immune to electricity.

"This should work," Sektor, says after being enchanted himself.

At the Owl House, the heroes had introduced themselves to each other and were planning their next course of action.

"My suggestion remains we all attack the emperor's castle together take the pieces of the portal. Then we rebuild it ourselves to get back to Earthrealm," Liu Kang said.

"The emperor is very powerful, and he has an army of his own," Eda said.

"Me and Liu Kang can take them on Liu Kang has bested Shao Kahn twice," Kitana said.

"Last time we were there Eda was almost petrified, and she lost her magic," Luz said.

"We can't just keep sitting here doing nothing we need to get back to Earthrealm," Jax said.

"Trust me, I want you gone as soon as possible this place can't fit this many people," Eda said.

"Mittens is not being put in danger either," Emira said.

"We are not getting anywhere with this it would be better if my friends handle this one our own," Liu Kang said.

But before anyone could react to Liu Kang saying that everyone heard some footsteps it was the Tekunin approaching. They all looked outside to see Sektor battling Hooty to get inside The Owl House. Hooty put up a good fight, but he was no catch for Sektor's tech as he burned Hooty. And Cyrax trapped Hooty in a net not killing but incapacitating him.

"Sektor," Kitana said after opening the door to see what was going on.

"My Cyborg army will burn this place to the ground I recommend that you surrender now," Sektor said.

"Shao Kahn must have sent him, he would be here as well," Raiden said.

"You fool Raiden Shao Kahn is dead my new masters are Quan Chi and Shang Tsung," Sektor said.

"What happened Sektor?" Liu Kang demanded to know.

"You won't live long enough to find out Liu Kang, Cyrax cyborgs attack," Sektor shouted.

The cyborg army started rushing towards The Owl House, so all the heroes got out and took them on. They were not working very well together, though with most going after one or two on their own.

"Cyrax please snap out of it, we know you in there somewhere," Sonya said while facing down Cyrax. Cyrax however, had been badly corrupted, so he trapped Sonya in a net and Jax started fighting him.

Edric and Emira Blight rushed up to Sektor. They intended to use their same electricity illusion that worked on him the first time. When they tried to use it Sektor shrugged it off.

"Why isn't it working?" Edric said.

"A gift from Shang Tsung, you may say," Sektor said. After which he launched a missile at both of them. Surprising them and knocking them to the ground unconscious. Sektor tried to finish them off, but Liu Kang stepped it kicking him back.

"Shang Tsung's magic will not save you, cyborg," Liu Kang said.

"You assume too quickly Liu Kang," Sektor said.

Sektor and Liu Kang then started fighting. Liu Kang first rushed up to Sektor to punch him, but Sektor teleported and uppcutted Liu King. He tried to teleport to where he was knocked to hit Liu Kang again, but he blocked it and counterattacked. Sektor quickly teleported back to Liu Kang and shot his flamethrower at Liu Kang. Liu Kang countered with his flamethrower though from his hands.

The two clashed for a bit and knew they weren't getting anywhere. So Sektor teleported right behind Liu Kang and attempted to punch him. Liu Kang turned around and blocked the punch and the two started getting into a fistfight. Sektor however, due to him being made out of metal won the first fight and knocked Liu Kang to the ground. Sektor attempted to once again finish off his enemies, but this time Luz shot a fireball at him.

"Stay away," Luz said.

"I guess it's time for another fight, then, this should be easy," Sektor said. Sektor and Luz started fighting with both standing from a distance and shooting their projectiles at each other. Sektor launched one of his missiles and Luz would use her fire glyph to destroy it. When Sektor would use his flamethrower Luz used her ice glyph to freeze it.

Sektor teleported to Luz and attempted to again shot her with his missile, but Luz dodge rolled out of the way. Then she used her ice wall glyph on Sektor knocking him back. Sektor got back up and used his flamethrower again to burn the ice wall. He then shot another missile and Luz which she again destroyed. Sektor was fed up with the constant back and forths, he came up with a plan he launched another missile which Luz would destroy. While she was distracted Sektor teleported behind her and pushed her down.

Sektor got out his flamethrower and attempted to burn Luz, but she regained enough conciseness to use an ice glyph to hit Sektor. It also hit him in a bad spot damaging his armor a bit, though not enough that he had to stop fighting. Sektor teleported back to Luz and since she was still getting back up, he was able to kick her back unconscious.

Sektor was about to finish Luz off when for the third time he was interrupted this time by Amity Blight who saw Luz in trouble and came to protect her.

"You won't harm Luz Sektor," Amity said while shielding Luz.

"Oh are you here to protect your little girlfriend," Sektor, said only intending it as a joke to make fun of her. Sektor however, had no idea what he had unleashed. Amity was shy about her crush on Luz and Sektor mocking her that way caused her to go berserk.

Amity screamed and angrily summoned a massive abomination. Sektor was a bit taken back, but he got out his flamethrower and attempted to burn the abomination. It waked through it and punched him. Sektor got back up and was quite impressed by the strength of the Abomination. He was not deterred and teleported behind amity to fight her.

Sektor got out his flamethrower again and shot it at Amity, but she used a shield spell to absorb it. Sektor then fired a missile at her which Amity used a fire spell to destroy again as Luz had. Amity to counter back, summoned a humanoid abomination to fight Sektor, which they did in hand-to-hand combat.

Despite the strength of the abomination, it stood no chance against Sektor, and he eventually cut It down. Amity, however, had bought some time, so she summoned an even bigger abomination which Sektor had to again take on. This time he attempted to use his flamethrower to burn it down, but it wasn't having any effect on him.

He knew he couldn't take this on alone, so he called Cyrax who had beaten Jackson Briggs over. Cyrax took on the abomination while Sektor teleported near Amity. Sektor tried to use a blade on his body to cut her down. Amity was able to dodge out of the way and use a fire spell to counter him. Sektor took it pretty well though, and continued to try and get in a hit on her.

Sektor was able to hit Amity in the foot with his flamethrower burning her and causing Amity to lose her focus. Sektor used his opportunity to kick her knocking her back on the ground. Sektor then teleported to her uppercutting Amity to the ground unconscious.

Sektor was on a roll, taking out three opponents in a very short window. These were starting to tire him out and Kitana saw that as an opportunity to take him out. She threw her fans to Sektor which he was only barely able to dodge out of the way of.

"Your aim is off Kitana," Sektor said.

"I wasn't trying to hit you," Kitana said. After which the fans circled back around to Kitana and cut one of his cybernetic hands-off.

"Ow, you will regret doing that," Sektor said. He then teleported next to Kitana and the two started fighting in hand-to-hand combat. Sektor however, was losing due to losing one of his hands, he was having a very hard time fighting her. He was still a competent fighter though, and he was able to stand his ground against Kitana, but he was losing.

Kitana was eventually able to get the upper hand and was ready to finish Sektor off. But Cyrax had noticed his taste ran trouble and came in to fight Kitana himself. While Kitana was taking on Cyrax, Sektor got back up and the two started fighting Kitana together. Kitana was a competent fighter, but even she was no match for the two cyborgs working together. They are eventually able to overpower her and knock her unconscious.

The heroes had trouble working together and due to their limited numbers compared to the cyborg army. They were all overpowered, though not without many losses from the Tekunin. Sektor had finally been able to stop fighting constantly, so he was ready to finish off all the heroes. Raiden sat back unable to do anything without the approval of the Elder Gods. So he knew he needed to talk with them to get them involved. He needed a distraction for Sektor though since everyone was at the mercy of Sektor.

Luckily for Raiden help was just about to arrive.
