A self-indulgent idea that sprung from the question of "Who wins in a fight, Raiden, god of Thunder or Kamen Rider Gaim?"
Kouta was simply going on his business on the new planet he created when he felt something was invading his domain.
He was able to get glimpses of the life he left on Earth as Zawame's armored Riders used the powers given by the Helheim forest to protect the city, the country, and the world as a whole. He was even able to power up Zack's Jimber arms despite them being lower class lockseeds, and were weaker than his or Kaito's have been.
"Kouta, what's going on?" Mai asked, concerned.
"You feel it too?"
"It's trying to eat our planet."
Suddenly, multiple zippers appeared near them. Both former humans took a risk and glanced down at the opening the zippers created as the lockseeds' respective fruits descended to it.
There both former humans saw the chaos that surrounded their former home planet. Literal lines between dimensions appeared on the streets of Zawame as unknown creatures indiscriminately attacked civilians.
"Kouta…"
"You know we can't, Mai." Kouta shook his head. "We risk having the Helheim forest invade Earth if we meddle in their affairs too much."
"But…"
"Interesting, a power unknown to me."
"What would you have us do?"
"Capture those people who transformed using fruits and bring them to me."
"Someone's attempting to reach for the forbidden fruit," Kouta frowned. "I can't turn a blind eye to this."
"If you're going there, bring some of the Helheim's fruits to them," Mai suggested. "I feel like we are going to need every help we can get."
Kouta waived his hand and weaved himself a small basket where he stored a few of Helheim's fruits.
"Be careful, Kouta."
"I will."
Kouta teleported from his planet, via opening a zipper, to Earth but his surroundings were unfamiliar to him.
"Who dares trespass Earthrealm's Jinsei?!" A commanding voice demanded.
"T-trespass! You're the one invading my world!" Kouta replied indignantly.
"Japanese?" The voice questioned. "Perhaps an Earthrealmer?"
Suddenly a lightning strike occurred indoors and a man wearing a triangular straw hat appeared before Helheim's god.
"You're no Earthrealmer!" The man that appeared through lightning growled. "Begone from this place vile creature."
"V-vile?!" Came another of Kouta's indignant reaction. "I'll have you know I was once human!"
"Your lies will deceive no man, to the Netherrealm with you!" The man exclaimed. "You face Raiden, god of Thunder."
Sensing an attack, Kouta had forgone his usual transformation routine and materialized his Kiwame arms around him as a banana-themed spear and an orange-themed sword appeared in his hand.
"Peculiar weapons will not save you."
"Let's see about that!"
Raiden vowed to send the creature that looked human to the Netherrealm as quickly as he could. It appeared that dimension was fusing with another, and this time he cannot count on the Justice League's assistance, as they do not exist in this dimension.
Try as he might to search for the Justice League but he could not find them.
According to Takeda's reports, there were heroes in the land of the Rising Sun called Kamen Riders and Sentai, masked people who fought this dimension's various threats.
They were however urban legends with no way of validating them as fact or fiction.
As Raiden absentmindedly fought the creature, he couldn't help but admire the creature's kombat. This one was strong, strong enough to rival him, the god of Thunder.
"Kiwami Au Lait!"
Suddenly bananas erupted from the ground and sent Raiden flying to the Jinsei's roof. He had not expected this creature to be matching him in every aspect, he hadn't even expected that he, as someone who wasn't holding back, to be matched by this unfamiliar creature.
Raiden shook his head before he sent multiple bolts of electricity to his opponent, all of which were blocked by a melon-themed shield.
Kiwi-themed chakrams were then thrown at the thunder god, which was swatted away easily.
"Ichigo charge!"
A huge strawberry appeared before Raiden before it barraged him with multiple strawberry projectiles that couldn't defend at once or else he'd destroy the Jinsei.
Raiden needed to be on the offensive. He cannot stay on the defensive. He decided to taunt the creature into following him.
"I must laud you for trespassing my domain to attack me in an attempt to destabilize Earthrealm's champions," Raiden stated as he slowly descended from the ceiling. "You are one of the better warriors under Shao Kahn's thumb. However you are still weak for resorting to underhanded tactics, if you truly believe you can best a god, then follow me and we fight fairly."
"I don't have time for this!" Kouta growled as he teleported away from the cave.
"Peculiar."
