Tartarus was very quiet at this time of day. In the waning evening light, most of the prisoners were sitting in their cells, practically resigned to their fates. One such prisoner was the fallen Symbol of Evil, All For One.

The nearly-faceless villain was sitting in his cell, humming to himself while trying to ignore his itchy scalp that he couldn't scratch because his hands were confined beneath a straightjacket. However, he knew something was off when he heard the distant sound of gunfire and explosions.

Meanwhile, at the entrance to Tartarus, a handful of guards were firing at General Zod and Titanium Man, the bullets harmlessly bouncing off of the two villains. Two of the guards was instantly downed by Zod's heat vision, while three more were blasted to bloody chunks by Titanium Man's repulsor blasts. After the guards were dealt with, Titanium Man raised his hand and fired another blast at the large metal doors, knocking them clean off their hinges.

More guards trickled out of the hole where the doors used to be, only to be cut down by Ajax's battle axes, Doc Ock's tentacles, and Bane's bone-crushing punches. During the chaos, Overhaul calmly walked in to the massive compound, strolling past the various prisoners banging on the insides of their cell doors, each one wanting a piece of the action.

Overhaul ignored the dangerous convicts in favor of the most dangerous one of all. He grinned under his plague mask as he reached a cell at the end of the hall. This door led to the most powerful villain Japan had ever seen, and Overhaul fully intended to exploit that power. He cocked a robotic fist back and slammed it into the reinforced steel door, causing the metal to dent. He kept punching the door, the metal creaking under the effort of trying to hold him back, until he finally knocked the door off its hinges, and it fell to the ground with a resounding thud.

Overhaul stepped over the twisted and crumpled mass of metal and walked forward, coming face-to-face with none other than the Symbol of Evil.

"Hello... All For One," he said.

"Do I know you?" All For One asked.

"Oh, of course. Where are my manners? My name is Kai Chisaki, and we have come to bust you out of here."

All For One would have cocked an eyebrow if he had one. "We?"

Almost as if on cue, the rest of the Cabal walked in, all covered in the blood of the slain guards.

"I hope you don't mind... but I brought some friends."

The ragtag band of heroes arrived at Tartarus, by way of being carried by Superman and Iron Man. All of them looked over the carnage at the front gate with varying expressions of horror.

"Jesus," Mineta muttered, looking green at the sight of the eviscerated guards.

"I see singed corpses, people sliced to bits, people twisted into pretzels..." Iron Man said. "They were definitely here."

"Uh... what exactly did you say these guys could do again?" Kirishima asked.

Before anyone could answer, Overhaul walked out of the hole in the front with the Cabal in tow.

"Overhaul..." Midoriya growled.

"Well, look who it is!" Overhaul exclaimed. "Right on time!"

On cue, a familiar face stepped out of the hole and walked around the Cabal, clad in a three-piece suit and a menacing face-mask.

"Oh, you've gotta be kidding me," All Might muttered, his eyes widening.

"Ah, Toshinori, glad to see that your one lung is still working!" All For One exclaimed.

"Hey, isn't that the guy that fought All Might in Kamino Ward?" Kaminari asked Midoriya, whispering in his ear.

Midoriya gulped before responding. "Yeah..."
