Jet Jaguar and M11 charged at each other, grabbing each other in a grapple and beginning to struggle to overpower the other. M11 eventually got out of the grapple first and punched Jet Jaguar in the face. The machine then delivered a barrage of punches to Jet Jaguar, ending in a blow that sent him flying into one of the UNGCC soldiers. Jet Jaguar got up and picked up the soldier's rifle, beginning to fire it at M11.

The other soldiers joined in, realizing that M11 was the more immediate threat. Unfortunately, M11 walked through the bullets without taking any damage, and then teleported behind Jet Jaguar to backhand him in the face. Jet Jaguar stumbled back and attempted to respond with a kick, but M11 grabbed his foot and threw him away. He then teleported behind a soldier and forced him to open fire on Jet Jaguar.

Jet Jaguar punched the bullets away, but M11 suddenly teleported away again, this time behind Jet Jaguar. The older android began to choke the heroic one, but the heroic one managed to elbow M11 in the gut and delivered a roundhouse kick to his chest, knocking him down. Goro and Hoshiro watched the battle in awe, and Hoshiro reached into his pockets, pulling out a phone.

He quickly typed in a phone number and called his superiors, telling them,

"Got a situation here. M11 has arrived and is fighting Jaguar J. Our soldiers can't stop it. Requesting evac."

Goro looked at Hoshiro angrily and shoved him against the wall of the base, yelling,

"You! This is all your fault!"

Hoshiro smirked at him and replied,

"Careful, buddy. One wrong move and you could get 3 years of prison time. Probably more for harboring technology the government's been trying to sweep under the rug."

After a few moments of deliberation, Goro let Hoshiro go and turned his attention back to the fight. Jet Jaguar delivered an uppercut to M11, with the android responding with a knick that sent JJ flying across the room. Jet Jaguar skidded to a halt and then charged at M11, delivering a series of jabs to his midsection before ending with a punch to the head.

M11 stumbled back from these blows, and Jet Jaguar followed his momentum up by delivering a barrage of kicks and then attempting another roundhouse kick. However, M11 caught his leg and threw him to the ground. The malevolent android then grabbed Jet Jaguar by the neck and held him up, telling him,

"Your resistance is futile. There is no escaping your annihilation."

Jet Jaguar struggled to break free of the grip, but just as M11 was about to crush his neck, a gunshot rang out and a bullet bounced off of him. M11 turned around at this to see Hoshiro pointing his gun at him. The android put Jet Jaguar down and stared at the human, who then turned around and yelled at Goro,

"Go!"

"B-But-!"

"I SAID GO!!!"

Deciding to heed this advice, Goro began running away out of the lab. As he did so, M11 burst forward and punched Hoshiro right through the chest. As life began to leave the man's body, he looked M11 dead in the eyes and said,

"If only…we could have harvested….that….technolo….gyyyy…."

The android then retracted his fist, and Hoshiro collapsed to the ground, dead. However, before M11 could begin going after Goro, Jet Jaguar suddenly sprung up and grabbed him in a full nelson. As the malevolent android struggled to break free, the heroic one burst into the air, smashing through the roof of the lab and sending both of them flying towards an unpopulated area.

Once he arrived at his destination, which was grassy fields outside of any Japanese cities, he kicked M11 into the ground, creating a massive crater. Jet Jaguar then flew down as M11 got up, and the older android said to the heroic one,

"So you wish to not involve your friends in our battle. Very well. Unfortunately for you, they must not be allowed to inform the government of my presence. This mission must be completed without any knowledge of the public about these events."

M11 then fired an energy blast at Jet Jaguar, which the heroic machine dodged swiftly. Jet Jaguar responded by charging at M11 and delivering a right hook that staggered the other android. Jet Jaguar then began pummeling his foe again, causing M11 to have to teleport behind him. However, Jet Jaguar knew that M11 would try this, so as the older android prepared to deliver a double ax handle to Jet Jaguar's head, the heroic android responded by turning around and delivering a mighty blow to M11's own cranium.

M11 was momentarily stunned by this surprise hit, so Jet Jaguar took this chance to land another series of punches onto him, but this time he aimed for M11's head. He finished this combo by throwing M11 into the air and flying up, then spiking him to the ground so hard he created a crater. Once the smoke cleared, M11 was revealed standing in place, completely unharmed.

Jet Jaguar was shocked by this, and M11 then said,

"My turn."

M11 fired multiple green energy balls at Jet Jaguar, and while the heroic machine tried to fly away from them, they eventually struck and sent him tumbling towards the ground. Landing with a loud thud, Jet Jaguar began struggling to get up, and M11 took this chance to walk over to him. The older android lifted his foot and brought it down on Jet Jaguar's back, keeping the hero on the ground.

M11 then began repeatedly stomping on Jet Jaguar's back, causing the heroic android to squirm in pain. Finally, M11 stopped stomping Jet Jaguar and lifted him over his head, spinning him around and throwing him away. The older android then turned around to face the direction where Jet Jaguar had flown them from. He then got into a running stance and quickly took off at blinding speeds.

Meanwhile, Goro was being flown in a G-force helicopter by a G-force operative and was on the verge of having a panic attack. As he looked around, he noticed a small object running on the ground. He motioned to the pilot and asked him,

"Hey, do you see that?"

Not paying Gondo any mind, the pilot said to him,

"Sorry. Can't take my eyes off the window. I'm getting you to that G-force base as fast as I can."

Unbeknownst to either of them, the small figure on the ground was M11 chasing the helicopter down. The android was easily keeping up with the helicopter, and once he could get a clear shot, he fired a single energy ball from his palm at it. The helicopter's tail was blasted clean off, causing it to begin to shake. Panicking even more, Goro asked the pilot,

"Wh-what's going on?!"

The pilot hurriedly responded,

"That thing took out the tail and now we're heading into freefall. Hold tight, I'm gonna try to make a crash landing."

"WAIT, WHAT?!"

Before Goro could protest anymore, the pilot began lowering the craft. After a few agonizing moments, the copter crashed to the ground with a massive crash. Despite being somewhat wounded, the 2 passengers were alive. As Goro lifted himself out of the rubble, M11 walked up to him and menacingly said to him.

"Unknown human. Your knowledge of Jaguar J means that you must be eviscerated. Prepare to die."

M11 raised his hand, preparing to fire an energy blast at Goro. Goro closed his eyes, expecting the end, but suddenly heard a whoosh. He turned around and saw Jet Jaguar land on the ground with a mighty crash. The robot lifted his head as his eyes glowed a sky blue, staring down M11 with killer intent.

M11 was unmoved and charged at Jet Jaguar without saying a word. The 2 began trading fists once again, with neither getting the upper hand. Jet Jaguar attempted a right jab, which M11 avoided and attempted to respond to with a spinning kick. However, Jet Jaguar grabbed his leg and slammed him into the ground. He began launching punch after punch at the downed android, desperately attempting to take him down for good..

However, M11 managed to break out of Jet Jaguar's barrage by firing an energy ball at him, forcing the heroic android to backflip out of the way. M11 then got up and fired another blast at Jet Jaguar, which was deflected. The blast spun out and hit an apartment building, completely destroying it. M11 then began spamming more blasts at Jet Jaguar, which were also deflected.

At this point, Jet Jaguar was getting rather tired of this constant back and forth, and so charged at M11 with a punch reared back. M11 was about to dodge this, but Jet Jaguar suddenly leaped into the air and punched the ground, triggering a tremor that sent M11 flying into the air.

Jet Jaguar then flew up and clapped his hands together, unleashing a purple and blue energy beam that sent M11 flying into the ground with an explosion.

Jet Jaguar then flew to the ground and waited for M11 to come out, and sure enough M11 burst out and punched JJ so hard that he was sent into a nearby building. Goro cried out

"JET JAGUAAAARRR!!!!"

Upon hearing Goro's voice, M11 then turned around and told him,

"Now to eliminate any witnesses."

However, before M11 could follow through on his threat, he suddenly heard something. Turning around, he saw something that stunned both him and Goro. Jet Jaguar, now 100 meters tall, burst out of the building leaving behind an explosion. The machine then glared down at M11, his eyes going from yellow to blue.

That was to signify Jet Jaguar's anger at M11 for trying to hurt his friend, and as the 2 machines stared into each other's eyes, they and the observing Goro all knew that the battle was already over, and M11 had already lost.
