Oozarus against two people in a city.
Every citizen saw the Oozarus and screamed in terror.
Batman and Chronoa are on a rooftop.
One of the Oozarus attempts to crush the two with its fist.
Chronoa teleported her and Bruce away from the attack. The fist instead crushed the building.
While flying, she's holding Bruce's hand. "It might be time for you to take this seriously.", Chronoa suggested to Bruce.
"Everything I do is serious.", Batman assured her. Then he gets Chronoa to let go of him as Batman makes his body float using his flight ability.
Both fighters noticed a hand is reached out to them. They evaded it. Together, they struck a knee at the Oozaru's face, staggering the gigantic beast. The beast felt pain, and responded by blasting energy from his mouth, which Batman and Chronoa dodged.
Batman turns. An Oozaru is going to try and crush him by slapping his two hands. As the two hands made contact with Bruce, Batman uses a portion of his true strength to hold both hands. He then flied toward the Oozaru's face and punched him. The Oozaru stumbled away. Batman flied over and punched his abdomen before landing a heavy blow under the Oozaru's chin. The Oozaru lies in the ground.
Chronoa uses her powers to freeze all the Oozarus that tried to attack her. She then sped around, and struck every Oozaru away. Afterward, Chronoa almot made contact with one of the Oozarus' hands. She dodged it, and threw the Oozaru with her telekinesis to fall to the grounds. Chronoa dodged another Oozaru attack, and then kicked the Oozaru's head down, making the creature fall to the ground.
Batman kicks an Oozaru backward and strikes it twelve times, bringing it to the ground.
Behind Batman, Oozaru fires an energy blast. Batman turns, seeing a blast flying toward him. Batman creates a force field made of energy around, shielding himself from the blast. The contact brought about smoke. Batman emerges from the smoke, and attacked his attacker, resulting in the Oozaru falling down.
Following the defeat of numerous Oozarus, Batman and Chronoa reassembled.
"The entire city, and probably the entire world, could be destroyed if we carry on with this conflict.", Chronoa said while sighting Oozarus standing up again.
"The tails.", Batman said. "Cut the tails off.". Batman uses a technique that lets me bring out a razor-sharp disc of energy. This technique is the Destructo Disc. Batman never intended to use it as he is against killing people. One attack can end any person's life. In this occasion, Bruce is using it to revert everyone's Oozaru forms to their base forms. Bruce fires the Destructo Disc at an Oozaru, it instantly sliced his tail off, resulting in the creature getting smaller until it reached its normal form.
Chronoa also knows the technique, Destructo Discs. She fires two Destructo Discs at all Oozaru's tails, cutting their tails off.
Each tail cut, there are less Oozarus.
"Oh my, this is... unexpected.", Jervis Tetch said in his transmission to Batman.
Finally, Batman and Chronoa reverted every Oozaru back to their base forms which resulted in the victims of Jervis Tetch becoming senseless.
"Useless brawns!", Jervis shouted in anger.
"Show yourself, Jervis Tetch.", Batman demanded.
"Your performance pleases me, Batman.", Jervis commented. "I have sent the coordinates on your scouter.".
Given Jervis's coordinates, Batman finally knows Jervis Tetch's location.
"You're going to confront him?", Chronoa asked.
"The girl is trapped with the bastard. I have to.", Batman said.
"Then proceed.", Chronoa allowed.
"You're not coming?", Batman asked.
"He's not as deadly as the Oozarus. And you have been trained to resist mind-control. Is there a reason for me to help you bring him to GCPD?", Chronoa said.
"Hmm, good point."
After the fight with the Oozarus and separating with Chronoa, Batman arrived in Jervis Tetch's location.
Once he went inside, he fought a dozen men that are mind-controlled by Jervis Tetch. Eventually he defeated them, which made him free from Jervis Tetch's mind control.
Batman made his way through the rooms till he meets Jervis and a few thugs. Batman quickly beat them before moving to face Jervis Tetch.
"You came! How wonderful! It really is an honor to make your-", Jervis Tetch is cut off when Batman pinned Tetch.
"Where's the girl?", Batman demanded.
"W-whatever do you mean?"
"Alice."
"Excellent, then you know why you're here!", Tetch said.
"What are you talking about?", Batman questioned him.
"Oh. Perhaps we don't see eye-to-eye after all. Let me remedy that!", Tetch said.
Tetch uses his powers to control the Batman.
Batman pitches backward.
"You are now under my control Batman.", Tetch said, grinning. Batman suddenly broke free of the hypnosis much to Tetch's shock. "What? No! You ruined everything!". Tetch gets the girl out, holding her as hostage.
"Help me!", the kidnapped girl cried.
"He can! He will! He just has to leave! He can! He will! He just has to leave! He can! He will! He just has to leave!", Tetch sings. "Really now, you're becoming my pet peeve.".
Batman fires a batarang. Before it hits, someone popped out and shielded Tetch from the batarang. Batman is astounded. He looks at what stopped the batarang from hitting Jervis Tetch. A big creature that is brawny.
The creature charged at Batman pushing him backward. Batarangs were fired at the beast once Batman regained his balance. The creature is unharmed and moved fast over to Batman's way. Batman leaps and climbs onto the creature's back. He steered the creature to crash at a few furniture. Some of it knocked Jervis Tetch out which caused Tetch to lose control of the creature. Both the creature and Tetch lost conscious.
Freed, the girl stumbled to the chair as she starts crying.
Batman places a call to GCPD for a trauma unit for the poor girl and squad vehicle for Tetch's arrest. He then comes to the girl. "Don't worry. You're safe now.", he reassured the girl.
The girl slowly looks up. "No. It's not.", she said before sobbing again.
Batman knows there's nothing to do here. He has other things to do. Not all of the assassins have yet been eliminated, and Tetch wasn't even an assassin. He departs the building letting the GCPD handle this.
