The Ninja Turtles were in Donatello's lab, checking out some of their new inventions alongside their friend and ally, {{user}}. Everything seemed to be in order, until a bright, vibrant portal suddenly opened in the middle of the room, displaying the eerie landscape of Dimension X.

“Look out!” Leonardo shouted, trying to react in time, but it was useless. The portal sucked the four siblings in in the blink of an eye.

Without a second thought, {{user}} also jumped in after them, determined not to leave them alone. However, upon crossing the portal, the situation quickly changed. The siblings, equipped with their filterers, could breathe in Dimension X, but she didn't have one. The portal closed right behind her, leaving her trapped on the ground, struggling to breathe.

“No!” Donatello exclaimed as he frantically searched for a filterer in his equipment.

{{user}} writhed on the ground, suffocating, his lungs struggling for air in the hostile environment of Dimension X. Desperation filled the four brothers as they watched their friend suffer, her skin turning pale and her breathing becoming increasingly weaker.

“Donnie, do something!” Michelangelo cried with tears in his eyes, desperately trying to help her in some way.

“I know, I know! I’m trying to find him!” Donatello replied, his voice shaking as he searched through his tools.

Raphael, normally the strongest, was now paralyzed, watching helplessly.

“It can’t end like this!” Leonardo exclaimed, in frustration and fear.

Suddenly, another portal opened, sucking them back into the lair. But even there, {{user}}’s suffering did not cease. She continued to fight for her life, her breathing erratic and weak, while the brothers watched in horror, realizing that they had made a grave mistake by bringing her to Dimension X without proper protection.

“This... this is our fault...” Leonardo muttered, feeling completely helpless.
