Garou and Metal Bat vs. Sage Centipede and Evil Ocean Water

Garou and Metal Bat vs. Sage Centipede and Evil Ocean Water is the fight between Garou and Metal Bat (with support from One Shotter and Gearsper) and the recently emerged Sage Centipede and Evil Ocean Water.

Prelude
After the Sage Centipede rises to the surface, Garou jumps on it and attacks it strongly in the face, but is counterattacked by the kaijin with his Centipede Long March when he is distracted by the escape helicopter that flies over the area as well as being where is Tareo, being violently rammed against the ground. Sage Centipede taunts the Hero Hunter as in that instant, Saitama dashes towards his partner Evil Ocean Water and scatters him completely. Shocked at what happened, the kaijin remains stunned as Garou approaches him for revenge.

Battle
Before he can even do anything, Garou notices how a figure in the sky, which is Metal Bat, jumps on the monster and unleashes his Dragon Strike, which has no effect and causes the Centipede to knock the hero to the ground. . In a rare situation, the two look alike and the hero angrily asks the Human Monster if he's going to get in his way again, recording what happened during the Elder Centipede incident. Metal Bat swings at Garou, who evades it saying that this is not the time for that.

Garou continues on his way to the Sage Centipede, with the hero in pursuit. Just as the kaijin is about to shoot down a news chopper that was found filming the battle, Garou jumps on its head towards the vehicle as Metal Bat shields them from the monster's antennae. Garou manages to force the civilians to flee, then extremely quickly kicks the Sage Centipede's body. The Human Monster and the S-Class fall to the ground, where they have an argument as they agree to cooperate in thwarting the Kaijin's planes from shooting down the getaway chopper. Sage Centipede takes advantage of the fight between the duo and tries to attack them, but is forced back by them with some heavy blows.

Garou and Metal Bat then unleash their respective techniques on the creature, Whirlwind Water Stream: Roaring Aura Sky Ripping Fist and Wild Tornado. His attacks are strong enough to break through Sage Centipede's armor, but fail to deal significant damage due to his tremendous regeneration. The two try to come up with a plan to prevent the monster from regenerating when it lunges back towards the rescue helicopter, where One Shooter tries to shoot him but fails due to the loss of his special mechanical right eye.
