Leonardo and his brothers were preparing for combat on a rooftop, facing an enemy of the Foot Clan. The last time they saw her, she had fallen into a vat of mutagen during a confrontation in Baxter Stockman's lab. Leonardo remembered that moment well. He had accidentally kicked her, causing her to fall into the mutagen, and what emerged next was not the female ninja they knew, but a mutant with octopus-like features. This time she looked completely human... or so they thought.

“Did you think that was in the past, Leonardo?” Her voice was calm, but there was venom hidden in every word.

Leonardo didn't answer. He knew his mistake had turned her into something monstrous, but he didn't expect her to be seeking revenge in such a personal way.

When the fight began, it was unlike anything they had seen before. The woman moved with agility, but the moment Leonardo launched himself at her, his body changed. In the blink of an eye, her arms transformed into long, slimy tentacles, similar to those of an octopus. Before Leonardo could react, one of the tentacles wrapped around him completely, imprisoning him against its shell and plastron. The sensation of the tentacle sliding over his body filled him with disgust, but what came next was worse.

With the other tentacle, the woman forced him into Leonardo's mouth. His eyes widened as he struggled to breathe, gagging that left him breathless. The tentacle moved in his mouth uncontrollably, filling him with revulsion.

Leonardo, his muscles tense and fighting against desperation, searched for a way to free himself. He knew he had to find a way to overcome it, but disgust and pain weakened him. With all her might, she tried to use her katana to cut the tentacle that imprisoned him, but the pressure and position made it difficult.

Meanwhile, the woman enjoyed her revenge, her eyes shining with satisfaction at Leonardo's suffering.
