Saturn Ruins. Underground cellar. Morning.

Harvie kicks aside rotting floorboards. Dust explodes everywhere. Ancient metal gleams underneath.

"Bloody hell." British accent cuts through the musty air. "Look what the old guard left behind."

She descends concrete steps into darkness. Motion sensors flicker to life. Strip lighting runs along the walls, struggling, failing, then blazing bright.

A training dojo frozen in time. But not any dojo.

Holographic combat bots line one wall. Projectors covered in dust and cobwebs. Training weapons with LED edge trackers. Gravity manipulation pads embedded in the floor. A massive digital mirror spans the far wall, cracked but functional.

Harvie opens a metal case. Inside, rows of black bodysuits with circuitry woven through the fabric. "Ahhh G.L.O.V.E. suits." She pulls one out, dust cascading off. "Gravitational Leverage and Overload Vestment Enhancement. Rather pretentious name for pain simulation."

"Helix Corp." Harvie runs her fingers over a logo. "This brings back memories."

Atlas appears at the top of the stairs. Takes it all in. No surprise on his face.

"Is this all still functional..."

Statement, not question. Atlas descends into his past.

"Twenty years since I've been down here." He touches a training bot. It springs to life, hologram flickering between human and combat drone forms.

Thirty minutes later.

The cellar transformed. Equipment humming with fresh power. Holographic opponents materializing and vanishing. The digital mirror showing heat signatures, vital points, momentum calculations in real time.

Everyone suited up in black G.L.O.V.E. suits. The circuitry glowing faint blue against the fabric. Like wearing lightning.

Harvie zips up her suit. DIRT-E's LED face displays a raised eyebrow with a tongue.

"That suit's fittin' a little snug around them hips, Harvie."

She doesn't even look at him. "Perhaps you'd like a closer inspection, you perverted little Roomba?"

"Hey I ain't no Roomba! Don't downgrade me like that!"

Drea bounces on her toes at the edge of a gravity pad. Eyes wild with manic energy. The suit makes her look dangerous. Donnie slouches against the wall, his G.L.O.V.E. hanging loose on his frame.

Harvie and three other Failures stand ready. Waiting.

"They call you broken." Atlas's voice, deep as bedrock. "They are not wrong."

He steps onto a gravity pad. The floor ripples beneath him like water.

"But the body remembers what the heart has forgotten. This memory lives in your bones, waiting."

Atlas moves through combat forms. Ancient fighting patterns mixed with future tech. The gravity pad makes him weightless, then doubles his mass. The digital mirror tracks every micro movement, displaying optimal strike zones in green, weaknesses in red.

"Andrea. Up."

Drea, suited in the G.L.O.V.E., practically launches herself onto the pad. Too eager. Too wild.

The gravity shifts. She stumbles. Catches herself. Throws a punch at a holographic opponent that materializes. Her form is sharp but sloppy. All power, no control. She misses everything.

"Focus yourself. You lack real anger. So you fight with the ghost of anger." Atlas circles her. "It is enough if you know how to channel it."

Drea spins. Kicks. The hologram dodges, counters. She takes a hit to the ribs. The G.L.O.V.E. flashes red, sending phantom pain through her nervous system.

"Ow! What the hell?"

"Pain is a teacher. Even when it is only a memory."

"Donatello. Up."

Donnie doesn't move. Scratches his wrist like a nervous teen, "I... really don't see the point in all this training... Like what am I even fighting for?"

The question hangs heavy. Other Failures shift uncomfortably.

Atlas steps close to his son. Voice low. Certain.

"You ask what you fight for. The answer has not changed. You fight because the alternative is death."

"That's not... exactly inspiring."

"Inspiration is a luxury you cannot afford." Atlas activates a holographic opponent in front of Donnie. It stands there, waiting. "War is already here."

"What war? We're... hiding in a basement. Or is this a cellar?"

The hologram suddenly lunges. Donnie stumbles backward, trips, falls on his ass. The other Failures try not to laugh. DIRT-E's LED face displays a laughing emoji.

"The war that does not announce itself." Atlas pulls him up. "Stand."

Donnie brushes himself off, embarrassed. Seeds of doubt planted. But also something else. Shame.

"We go again. Until your body knows what your mind resists."
