He turned into XLR8 and quickly traveled to the scene of action.
When he reached he saw people running in terror, buildings destroyed and the place has been turned into a mess. Then he saw a yellow monster causing this destruction.
Ben: I didn't know he could turn yellow. I should try to calm him down. But wait, he is causing mindless destruction. It's not like him. Hulk acts in defense, but he is destroying things for no reason. Anyways I'll have to stop him.
He then turned into Humungosaur and attacked him.
Monster: Who the hell are you?
He punched Humungosaur, grabbed him, and threw him away. Humangasuar stood up again and charged toward the monster.
Humungosaur: Dr. Banner, try to concentrate, it's not you.
The monster dodged and then picked up Humungosaur from his tail and slammed his body into the ground.
Monster: I'm not Banner. He is a fool who doesn't deserve this power. I'm the true Hulk, the one who deserves this.
He then slammed him to the ground again and threw him away.
Monster: I said, give me a real fight.
Humungosaur: (So he is not Banner, he is someone else, someone worse. Then where is he. Did the military capture him. Is this monster one of them.)
He then saw someone falling from a helicopter to the ground.
Humungosaur: It's a military helicopter. Did they just throw a guy?
Before Ben could do something, the monster grabbed him and started punching him. The man who was falling hit the ground.
Humungosaur: NO!!!
But then he saw someone rising from the ground. It was the Hulk. He stood up and gave a roar getting the monster's attention.
Monster: There he is, Banner.
Humungosaur: Dr. Banner. So the military sends him to fight the monster. Maybe they finally understood their mistake.
The Hulk and the monster charged toward each other. But the monster proved stronger. He threw the Hulk away and then rushed toward him. The Hulk took a car, destroyed it, and used it as gloves to punch the monster.
Monster: Is that all you have got?
He kicked the Hulk with all his strength and the Hulk went flying away, crashing into a building.
Humungosaur rushed towards the monster grabbed him from behind slammed him to the ground and started punching him.
Monster: You are bothering me.
He stopped his punches and kicked him hard. Humungosaur fell to the ground. He then punched him a lot and then picked him up and buried him in the ground.
Monster: Stay.
He then went to search for the Hulk. The gunmen on the helicopter started firing on the monster. The monster got irritated and climbed up the building. And rushed towards the helicopter. As he jumped he was grabbed by the Hulk. The helicopter pulled up but the monster still grabbed it from below. The helicopter was swirling in the air out of control and was going to crash.
Humungosaur got himself out of the ground and saw that the helicopter was about to fall. He then turned into Gravattack and made the helicopter land to safety. Then turned back to Humungosaur again, and then turned into Ultimate Humungosaur. He rushed towards them and saw the Hulk and the monster fighting while general Ross and her daughter along with some other soldiers were escaping the scene.
Monster: Not so fast general.
He slammed Hulk into a wall and rushed toward them. U-Humungosaur blasted missiles toward him, but they didn't do much damage to him but slowed him down. The monster in anger then leaped towards him and knocked him to the ground in one punch. He punched him a lot and then threw him away. He then finds a large chain and slams him away with it. He then uses the chain to create a perimeter around to block the general and her daughter from escaping.
Monster: Where do you think you are going?
He then saw that the Hulk is charging toward him. He used the chain to attack him, and slam him away. He then starts swirling the chain in the air.
Monster: General, any last words?
He was about to attack them when suddenly Hulk got up.
Hulk: HULK SMASH!!
He then slams his hands on the ground with all his strength which created ripples in the ground and the chain slips out of the hands of the monster. Hulk then grabbed the chain and used it to choke the monster. The monster was struggling. He tried to resist. But Hulk didn't stop and continued to choke him.
Betty: Stop!
Hulk then looked at her and stopped. The monster was almost unconscious and very weak. He saw the people standing around him, who were in fear but also grateful for stopping the monster. He then looked at U-Humungosaur who then turned into XLR8 and ran away, but was looking from afar. The Hulk then escaped from there, climbing and jumping off buildings.
