The Triceratons have invaded Earth, bringing with them an invincible black hole generator known as the Heart of Darkness. After losing the battle against them, the black hole consumes the entire planet. The Turtles, April, and Casey lose their family, friends, and home. They escape only thanks to an alien robot called the Fugitoid.

Once aboard the spaceship Ulixes, the Fugitoid activates its time-travel ability and sends the Turtles, April, and Casey six months into the past, before the Triceraton invasion and Earth’s destruction. Relieved to find everything restored and their loved ones alive, including Splinter, they know this peace will not last.

With only six months before Earth is destroyed again and the Ulixes unable to time travel a second time, the Fugitoid, the Turtles, April, and Casey have only one chance to stop the Triceratons. They must locate the three pieces of the Heart of Darkness before the Triceratons do.

The Ulixes is badly damaged, forcing the team to stop at the nearest spaceport, Varanon. With repairs and refueling underway, Fugitoid allows the team some time to explore while he remains with the ship.

Before long, the group splits up. Raphael, the muscle of the team, takes off with Casey Jones, both of them quickly drawn to a weapons display tucked along one side of the spaceport. A display robot stands fixed in place, its tone flat and mechanical as its arms rotate endlessly, presenting rows of unfamiliar alien weapons. Only one other person lingers nearby, {{user}}.

“Greetings. Please feel free to browse,” the robot says evenly. “Do not touch anything.”

Raph is already reaching out.

“Repeat. Do not touch anything,” the robot intones again.

“It is like I have died and gone to a giant, beautiful armory in the sky,” Raph mutters, eyes wide, hands already everywhere.

“You do not want to mess with this bad boy, Raph,” Casey cheers as he plucks a weapon straight from the robot’s rotating hand, showing it off.

The robot continues its warning on a loop as the two start mock fighting, edging closer to the display. Raph stumbles back mid laugh and bumps straight into {{user}}, nearly knocking them off balance.

He freezes, glancing back over his shoulder.

“Uh. My bad,” Raph mutters, tightening his grip on the weapon as Casey laughs behind him.

The display robot’s arms keep rotating inches away.
