Heihachi was spending his free time relaxing as Kuma was apparently playing, rolling back and forth on his back, when suddenly, a loud scream filled the room, alerting both fighters and causing them to brace themselves in whatever way they could, Heihachi merely being able to stand his ground in an Akuma-like stance, Kuma having to dig his claws into the floor. Sindel finished screaming and walked up to Heihachi stopping about 5 feet away. "So, you are the old fool Shao Kahn has sent me to destroy. You're certainly more spry than I'd imagine. That scream blows most others away with ease." She said.

"Someone has a death wish." Heihachi growled, preparing to battle. "I consider myself a chivalrous man, but I do not tolerate attacks on my home." He said.

Kuma prepared to rush in to aid his master, but was stopped when he was grabbed from behind by Goro. "Not so fast." The Shokahn said, struggling with the bears weight and fell back, hurting both of them, but getting them in their own battle. "I will make a feast and coat out of you." He said as he continued to approach the bear.

(Bear tastes awful! Go eat some chicken instead!) Kuma roared and rushed in, Goro holding him back, but the bear was still able to claw at Goro, raking his claws across the Shokahn's chest and cutting his leg and calf. Kuma also managed to bite into Goro's shoulder before the Shokahn decided to use his lower arms, slamming a fist into each side of Kuma's ribs, then picking up the bear and throwing him a ways away. Kuma quickly got up and charged on all 4's at Goro. The Shokahn leapt forward, but at that moment, Kuma pounced and tackled him to the ground. Kuma bit into Goro once again and started to tear away some flesh before the shokahn retaliated by firing an energy ball into Kuma and throwing him off again.

"You are a troublesome beast. I will have to dispose of you quickly." Goro said as he stood up once again.

(I don't think you can!) Kuma roared standing on his hind legs and charging in. Goro fired another energy ball at him, but he went onto all 4's, dropping underneath the attack and popped up, swiping his claws at the shokahn, who managed to step back enough to dodge the first one, blocked the second one, holding the arm and prepared to throw two punches to the bear's ribs again, but Kuma brought his leg up and cut Goro's leg with his claw again, actually bringing the shokahn to one knee because of how he raked his leg with the claws, then took a bite out of Goro's neck. The shokahn screamed in pain, pulling Kuma back and throwing a few punches to his ribs, but unfortunately, when he pulled him back, since he was still biting into his neck, Kuma ripped a good sized chunk of flesh out of the Goro's neck.

Losing blood fast, Goro knew he needed to end the fight NOW. He swept at Kuma's legs but the bear managed to jump back and now used more diverse moves Heihachi had taught him, a jumping round kick, a knife hand, which allowed for another strike to the weakened Goro's chest and finished a front punch, jabbing his claws into Goro's chest again. Goro fell back, slowly losing consciousness from lack of blood and exhaustion from his fight. He threw one more kick with both legs, catching Kuma in the stomach and knocking him back down, but nothing he wouldn't recover from. He stood up once again and walked back over to his weakened foe, jumping into the air and crashing down on his foe with his full weight, crushing Goro's ribs and doing massive internal damage in the process. To make sure his opponent wouldn't trouble him again, Kuma bit down on and tore out Goro's throat. The battle was over, the shokahn a bloody mess of his once living self and Kuma with a few broken ribs, some bruises and a bit of blood, but compared to getting thrown out of a helicopter, it wasn't that bad. Dropping back down on all 4's, he crawled back into his master's house and was greeted by a pleased Heihachi.

"Ah, Kuma! You took down your opponent as well! Good job, old boy!" He said, kneeling down and petting the bear, even leaning in and offering him a hug, before standing up. "Now, let's get you fixed up. Then we can take HER to the rocket!" He laughed, gesturing to Sindel's unconscious body (Spoiler alert!).

Reasons for the outcome:

1: Kuma has a speed advantage over Goro, giving him an edge.

2: Goro lacks the sharp teeth and claws other shokahn (Kintaro) have, giving Kuma another advantage of having more deadly attacks, being able to cut and wound Goro much easier than the shokahn could to him

3: Goro's fighting style is fairly predictable, slow and clumsy, leaving many openings in some cases. Also, while I didn't add this, his arrogance often leaves him open in the same way it does Shao Kahn. Kuma's fighting style is a mix of his vicious and instinct-prone tendencies of any bear combined with Heihachi's powerful martial arts style, which gives Kuma more diverse skills and makes him less predictable than Goro.

4: This one is up for debait, but Kuma, like most grizzly bears, is rather bulky, so with a layer of thick fur and a decent amount of fat beneath it offers him more protection than what Goro has, making him slightly harder to hurt. It would be like you punching The Rock, then punching a really fat guy. It would hurt more punching The Rock, since he has big muscles, but he'd probably feel it more than the fat guy
