The lights in the training room flickered as the reinforced doors sealed shut.

On the observation deck above, Tony Stark leaned forward over the railing, curiosity sharp in his expression. Beside him stood Natasha Romanoff, arms crossed, assessing. No one spoke.

Down on the mat, you stood alone.

Across from you were the two most experienced fighters on the team.

Steve Rogers adjusted the strap of his shield, jaw set but not unkind. “This isn’t about hurting you,” he said evenly. “Just show us what you can do.”

Next to him, Bucky Barnes rolled his metal shoulder once, the faint whir of servos cutting through the silence. His blue eyes were steady on you—not hostile. Calculating.

“You don’t have to hold back,” Bucky added quietly.

A beat of stillness.

Then you moved.

To anyone watching, it looked like you vanished.

Steve barely had time to raise his shield before you were already behind him. Your hand caught the rim and twisted—metal screeched against metal as you used his own momentum to flip him hard onto the mat. The impact echoed.

Bucky lunged, faster than most could track.

You were faster.

He swung—vibranium arm aimed to pin, to contain. You ducked beneath it, your reflexes sharp as lightning, fingers catching his wrist mid-strike. The strength behind your grip shouldn’t have been possible. You pivoted, using his own power to throw him across the room.

He hit the wall with a thud that cracked reinforced concrete.

Three minutes hadn’t passed.

Steve was already back on his feet—soldier instincts overriding shock. He charged, shield-first. You met him head-on. The collision rang out like a gunshot.

Your eyes flashed.

Bloodshot veins spidered faintly beneath the surface, irises sharpening. Fangs grazed your lower lip as you snarled low in your throat—not feral. Controlled.

Steve faltered for half a second.

That was enough.

You swept his legs out and disarmed him in one fluid motion, shield skidding across the floor. Before he could rise, you pinned him—knee to chest, hand at his throat, not crushing… just reminding.

Behind you, Bucky surged forward again.

You didn’t turn.

You didn’t need to.

You caught him mid-charge by the collar, pivoted, and slammed him down beside Steve with enough force to leave spiderweb fractures in the mat beneath them both. Your knee pressed to Bucky’s metal forearm, immobilizing it.

Silence.

The timer above buzzed.

Two minutes and forty-three seconds.

From the observation deck, Tony let out a low whistle. “Well. That’s… new.”

Below, Bucky didn’t look angry.

He looked stunned.

And impressed.

His chest rose steadily beneath you as he met your eyes—really met them. No fear. No revulsion. Just something thoughtful.

“You’ve been trained to fight,” he said quietly.

A pause.

“But you chose not to kill.”

Steve exhaled, still pinned but not struggling. “That’s what matters.”

The room felt smaller suddenly. Quieter.

Bucky’s gaze softened just slightly, voice low enough only you could hear.

“HYDRA made you into a weapon,” he murmured. “We won’t.”

Above, the doors unlocked with a hiss.

Your first test was over.

And somehow, instead of looking at you like a monster—

Bucky looked at you like he understood exactly what it meant to be one.
