Everyone picked themselves up, the heroes being more sympathetic to each other and helping one another. The only one standing was a changed Oroku Saki, the Shredder! His armor now covered more of his body and looked more frightening. All you could see were his eyes! In his hand was the very sword he sought. “…The power!” he whispered. “I had almost forgotten the legends! Tengu no Ken! The very sword with which my first ancestor, Oroku Sansho, laid villages to waste, brought castles to ground, vanquished armies! The sword that he used to conquer Japan and control the Tokugawa Shogunate as well as the Emperor! Now…this power is MINE!”
“Ours, my hubby-husband,” corrected Big Mama Joro. “That WAS the deal, was it not? And if you wanted to go outside, you really must learn to use the dimbly-door.”
“…And you, Big Mama Joro, would be wise to use the last few minutes of your life to use REAL words, not nonce,” growled the Shredder.
“Last few-?” Big Mama Joro’s eyes went wide, then she snarled, her fangs dripping with venom. “You picked a hell of a time to divorce me!” She leapt at the Shredder, but he side-stepped and fired an energy wave from the sword. The energy wave knocked Big Mama Joro onto her back, then the Shredder jumped onto her and ran the sword through her abdomen. She screeched in pain and thrashed as the Shredder stabbed multiple times…then her arm-pedipalps went limp, her face froze in a look of pain, and her legs curled up.
“…Huh,” said Donatello, rightfully horrified about how Big Mama Joro was executed. “…So…her vital organs are in the abdomen, just like a normal spider.”
“Perhaps I should figure out where a turtle’s heart is!” cackled the Shredder.
“Shredder, you reneged on our deal!” challenged Tormo. “You’ll regret it!”
“You said so yourself! I’m an entrepreneur! I see an opportunity and I sieze it!”
“Where you see opportunity, I see impulsiveness!” Tormo pulled out a communicator and spoke into it. “The Shredder has betrayed us! All hands, to my position!” The Lords then appeared.
“THE BORG?!” yelped Leonardo.
“No, the Lords!” replied Sengoku.
“More free-thinking than the Borg,” explained Jazz. The Lords then attacked.
“I’ll have your hide for this!” called Tormo as the Lords swarmed the Shredder.
“Try and take it!” The Shredder then cut down his attackers. …Well, there WAS one that was giving him trouble.
“Hiroki!” called the Lord. “Hurry! The Keystone! Shrink Leonardo!”
“Keystone?” asked Sengoku. He then remembered. “The Scale Keystone!”
“What?!” asked Leonardo.
“Leo-san, hold on!” warned Sengoku. “Scale Keystone, activate! Lessen scale of Leonardo!” Leonardo then shrank.
“WHAT THE?!” he yelped.
“Find a weak spot!” urged Sengoku. “Any weak spot!” He then threw the tiny Leonardo at the Shredder. He then turned to the renegade Lord. “As for you, call me a petty fanboy, but I preferred your usual suit instead of all that Borg kit.”
“I’m not going to insult you like that,” replied the renegade Lord, “because you’re right in how much better the suit is.” He then put his left hand to his waist and stuck his prosthetic right arm out past his left shoulder. He then moved the prosthetic in an arc towards his right. “Rider…” he said. A bulky area around his waist shattered as a cover split open to reveal a wind turbine that spun as the wind blew into it. He then pulled his prosthetic to his waist and thrust his left hand past his right shoulder. “…HENSHIN!” He then jumped high into the air and the Borg kit was destroyed as a green suit and helmet appeared. A red scarf then appeared on his neck as he landed. His suit looked a little bulky, but the helmet…dark green with red compound eyes, a pair of antennae, and a mouth plate to resemble a grasshopper’s mouth…that was all that was needed to confirm his identity.
“Takeshi Hongo!” cheered Sengoku.
“…The first…Kamen Rider?!” breathed Splinter.
“Dude! Dad used to obsess over him like Leo does with Star Trek!” said Michaelangelo. Speaking of which…
“Hey! Could stand to be big again!” called Leonardo.
“Normalize scale of Leonardo!” directed Sengoku. Leonardo then grew and almost toppled the Shredder, but was thrown off easily. His brothers helped him up.
“No dice!” he said. “The armor even covers the joints!”
“There’s gotta be something!” replied Raphael.
“Bah!” scoffed the Shredder. “A television hero tries to save the day?! I’m not a villain from your world!”
“But you ARE a villain!” retorted Kamen Rider Ichigō.
“Bringing order by any means necessary is NOT evil!” The Shredder attacked, but Ichigō, being the genetically altered cyborg he is, leapt out of the way. He then went on the offensive, throwing punches and kicks alongside the Turtles. Unfortunately, the Shredder could hit back hard, especially with the sword in his hands.
“It’s no good, Hongo-san!” protested Leonardo. “That sword’s made him too powerful!”
“We have to find a way to get it away from him,” said Sengoku.
“That won’t stop him,” replied Splinter. “Once the sword is reunited with the armor, the wearer will have untold power, even if the sword is separated from him.”
“His first ancestor attested to that?” asked Shockwave.
“That story’s been passed down the Foot Clan since it was first founded,” confirmed Splinter.
“Well, we gotta do something!” growled Raphael. “We can’t-! …Donnie?” Raphael turned to see Donatello looking at something.
“…Donatello, will you please pay attention to the situation at hand?!” snapped Sengoku.
“I am, Hishikawa-san. Look at the sword.” Donatello pointed at Tengu no Ken. Sengoku looked harder and blinked.
“Are those…are those runes dimmer?” he asked.
“I think so.” Donatello turned to Tormo. “Hey, Big Nose! Where did you find that sword?”
“How should I know?!” protested Tormo. “Rodimus Unicronus, where’d you find the sword?!”
“It was in the museum, on a sword stand you’d usually see Japanese swordsmen putting their weapons on,” replied Rodimus Unicronus.
“Do you remember any details about it?!” asked Donatello as he and his brothers rolled out of the way of the Shredder’s newest attack. “Hurry, man! The fate of the world depends on it!”
“Th-There was a plug in the stand! It was connected to the sword just under that alien octopus thing at the end of the handle-!”
“Hey, call me crazy, but are those runes getting dimmer?” asked Raphael.
“BINGO!” called Donatello. The Shredder looked down at the sword and realized Donatello and Raphael were right.
“What?! NO!” he shouted. As the runes dimmed, the armor slowly morphed from its mystic state back into its normal state.
