Mirror is analyzing the damage of Kenpachi, It had caused 0.5 damage to his system. This was impressive to Mirror as he underestimated Hero Works's S-Class heroes a bit as he is making Kenpachi the first to be killed.
Mirror quickly used his energy spheres to attack Kenpachi, however, Kenpachi uses to sword to attack the energy spheres as they were knocked back to Mirror. Mirror redirect them back to Kenpachi, but Suiko attack Mirror on the face as this interrupted his action as more energy spheres were knocked back to him.
Suiko quickly moved away as Crocodile made a sand wall to she don't fall to the ground that is hundreds of floors down. Mirror got launched out of The Hero Association building as he was slowly. Crocodile sees that Mirror is repairing itself as the cuts and dents were undone like regeneration. However, metal don't do that if they don't have material to work with, but maybe nanotechnology is at play.
Crocodile used his powers on Mirror, Mirror's hand turn into sand, but he quickly cut it as it was spreading like a virus and backed away. Crocodile can see that robots things were repairing Mirror without anyone noticing and Crocodile's theory is right, nanotechnology is at play.
However, Mirror was attacking at a distance to no be turned into sand and do damage. Mirror quickly attack buildings with civilians to distract Crocodile, but Mirror was so busy with Crocodile forget that they were another heroes around them, Kenpachi and Suiko knocked back all of his energy spheres at Mirror's arm to disable his attacks for a bit.
Suiko attacked multiple times, but her attacks were almost useless as they barely do any damage, if they was an damage, Mirror would quickly repair itself to its undamaged state. She was knock into a supermarket, she was mostly okay and she had to rethink a new strategy as she noticed cans of alcohol.
Kenpachi is tearing his sword into Mirror, but Mirror repaied quicker than expected as Kenpachi take a punch to the gut and multiple energy all over his body. A large amount of smoke was created, Mirror quickly scanned the smoke to predict the next direct attack that Kenpachi would hit, they predict that Kenpachi would try to cut their head again.
Kenpachi do what Mirror predicted his attack as he used his extra arms to block the attack and possibly disarm Kenpachi from his weapon. This would increase his chances of killing him a bit more in his favor. However, Mirror don't expect Suiko to jump in the air as they do a around house kick to the face as it made multiple crack to appears.
Suiko don't stop her barrage as she used every void fist technique she know to defeat this machine monster, her final attack damaged Mirror's system by 5%. This caused Mirror to attack her with a combined attack of his energy spheres. Crocodile quickly made multiple sand walls to block the attack from hitting Suiko, but it went through the walls and Crocodile quickly pushed her out of the way as he takes all of the damage.
However, some of his sand survived the attack as he was regenerating his body back, Crocodile was blooding a fair amount as the burned most of his body and caused 4 degree bones as he quickly covered them with sand to prevent infections.
Kenpachi charge with a menacing smile as he attacked with his full force as it chops of fhalf of its body, but it repaired itself again as it does a giant combo attack on Kenpachi. Kenpachi quickly tries to attack the attack with his sword, but he was consumed by the blast as they were bleeding a lot of the ground. However, Kenpachi just laughs like a maniac as he is enjoying the challenge as he is cutting down a being that can repair itself and not be tired by him.
Suddenly, heroes from C to A had join the battle as they attacked as a group as they pushed Mirror away a bit as the strongest heroes attack Mirror at the same time, this caused Mirror's damage report that the combined attack had caused 65% more damage more than an average hero can deal out. However, thanks to All Might and Star & Stripe's training, the heroes of The Hero Association and Hero Works can deal a lot more damage than before.
However, Mirror attacked a slowly cutting the heroes down as they were powerful together to do some damage to Mirror, but Mirror is defeating a handful of heroes and the weak heroes were grabbing their injured fellow heroes to a safer place. Mirror used an attack that used 50% of his power as all of the heroes were covered, the heroes were knocked, barely alive, or heavily injured.
The injured heroes were trying to get up, but failed as they had so little energy left and they were barely conscious to think straight, but they were going to fight to protect civilians and their fellow heroes that are in need.
Crocodile is stored enough energy for a big attack as he used Dessert Espada to cut it in half as the sand slowly turns his metal and nanobots into sands. Mirror would rejoin as it would spread the sand as he cut half of a centimeter of his metal as the nanobots were repairing him, however, Crocodile do a lot of damage to it as Mirror's movements were sloppy and locking up.
His system were damaged enough that his speed wasn't dragon level anymore as Crocodile hit the ground as he can barely lift him. However, he heard footsteps as Crocodile turns his head, he had a wide smile on his face as he can see the true hero coming in the scene, Saitama with his neutral face looked at Mirror. Mirror, however, judged Saitama's looks to guess he was any everyday weakling that would be killed by his hands, he will tear Saitama limb by limb.
