An explosion happened. The walls which protected them was shattered. There was now a huge hole in the wall they made. And with the fall of the wall the students and villains alike started to scream. At the forefront of the attack they saw a knight like zombie with heavy plated armor with a sword and a shield.
The zombie looked up and looked them straight in the eyes before it charged forward towards them. Thankfully for them the zombie's speed was still at an acceptable level.
"Die!" Bakugo shouted as he released a huge explosion in the direction of the zombie. And with a loud boom the explosion slammed into the zombie, throwing it back a few inches before it started to charge once again.
"Fuck." A villain said, he then created a water bomb before launching it towards the zombie. The bomb exploded right at the guts of the zombie, but it only pushed it back and left very little damage.
As they were attacking the zombie knight the other undead started to rush through the hole and they were starting to apply pressure onto the villains and students. Thirteen had popped one of the lids to her gloves and started to suck the undead in. A thin black like force started to push and pull the undead into her fingers.
She didn't want to do this. She rather use her quirk for good and to help others with it, not to attack and harm them, but her jobs as a teacher did allow her to be so non flexible. She would need to use her quirk for harm if she wanted the students to make it out alive.
The undead started to get sucked into her black holes at the tip of her fingers. But the undead were not as fragile as normal humans. One of the undead had managed to move to the side last moment and had slashed her suit, but thankfully the suit had protected her from the attack, absorbing the force. But she had to stop her attack and dodge the attacks of the undead.
As the students and villains worked together to save themselves from the undead the doors of the USJ were busted open. All Might had burst through the doors and launched an attack at the undead. Everyone cheered, even the villains. The undead were blown back and away. But they were still well and alive.
The undead got back up and started to charge once again. But under the strength of All Might they were thrown around. Suddenly the arms of All Might were dripping in blood. A ring like slash had cut the wrist of All Might. He looked around and saw that one of the undead was right before him. It was in samurai armor and fashion. It had in its hands a katana that was also dripping in some blood, his blood.
All Might then reeled his fist back and attempted to smash the undead, but it simply moved to the side and sent another slash. This one landed on the side of the hero. It didn't cut too deep but it still cut into the flesh. It then pulled back and jumped away.
All Might had tried to swing at the undead but he had missed as the undead jumped away. All Might attempted another punch, but was not able to land the strike. The undead had dodged the attack, even the shockwave of the attack was dodged.
They then continued their attacks. Which was mostly All Might attacking, the undead dodging and sometimes sending a few strikes himself. All Might would either tanker he strike, block it, or just dodge it as well.
As they went on like that the remaining undead had lost interest in All Might and had instead go after the villain and students. But because they were scattered the undead did not come in a huge wave but instead they came in small bunches or even by themselves. This made it very easy for the villains and the students to take care of the undead. Or at least the average and smaller undead. The undead warriors proved to be much more trouble.
A skeleton warrior brought its sword up and slashed down. The attack slammed into the arms of Kirishima, who had blocked the attack with his forearms which were hardened.
The others worked together and sent a barrage of attacks. But the undead dodged those attacks as did Kirishima. That was the problem. The undead warriors knew when to temporally retreat to preserve themselves so that they could more likely kill someone.
This went on for a for a good two minutes before the teachers arrived at the USJ. They too helped took the undead down. They were more professional than some students for thugs after all. It was obvious that they were also struggling. This only got worse when All Might was thrown towards them. He crashed into the ground right before them. They all turned their heads towards the attacker. Towards Senso Tsuyoi. But it didn't do anything it just turned around and started to open the gates to the tower before it entered it.
However, not before it turned around and with two fingers pointed towards his eyes and then at the students. Telling them that it would watch them carefully. It then walked into the dungeon before disappearing. The portal cracked was destroyed once the undead had stepped through.
"Is it me or did that undead just gestured to us about watching over us?" Present Mic asked the others. He turned towards the large mess of undead corpses that soon turned into light and entered their bodies. They could all feel the power corse through their veins and soon develop a core.
"So this is why people are so eager to enter the so call dungeons." Someone said, feeling the core power corse through their bodies as the core nourished them. But as soon as the villains and heroes were ready to get back to their roles. The dungeon gates opened wide.
It was forceful and loud. It went with a bang. And other side started to form a portal. The sparks of blue started to twirl and swirl. As they did, more blue sparks were formed from thin air before they formed a portal. And from the other side more undead came.
From the very front came a large skeleton wrapped in a large black cloth. It covered almost every part of the body, leaving only the feet and hands out of the wrappings of the cloth.
Behind it came a dozen skeletons knights. They wore metal armor, which protected everything. They had long sword and large shields. They marched in a very neat manner and with their chest puffed in pride.
The zombie knights behind them were slightly more sluggish and less neat. But their bodies exuded an aura of power and strength. They had large maces of all types with them. They marched with strength and power in each step.
And behind them were wraiths and spirits. They too were knights. They didn't march, mostly because most of them didn't even have feet. They floated along, bringing an air of mystery along with them.
Lastly were just a large ragtag gang of undead. They wield all sorts of weapons. And they wore all sorts of armor.
The leading lich reached out its hands and the undead quickly started to march.
