I do not own Digimon or any of its characters.
After Tai, Izzy, TK and Takato defeated BlackGreymon, BlackGrowlmon and ShadowSeraphimon, the group heads down infinity mountain, where they are greeted by the rest of the group waiting for them, among them is a person Takato knows well, yet is a stranger to everyone else.
"Guilmon!" Terriermon jumps from Henry's shoulder onto the head of the red dinosaur standing next to Takato. Guilmon falls on his back and starts to laugh.
"Henry, you're here?" Takato says surprised by Henry's presence.
"Me and Terriermon were looking for you, you were missing for 2 days!" Henry replies with a bit of anger in his voice.
"You two know each other?" Izzy asks curiously.
"Yes, we know each other, but who are you?" Henry replies while looking at everyone.
"We are-" Davis wants to respond but he is interrupted by Izzy.
"If you two know each other and you can confirm what Takato told us so far, my parallel universe theory is confirmed!" Izzy says excitedly.
Everyone except Takato stares at Izzy in confusion.
"Okay let me explain what I just said. I think Takato and Henry are from a parallel universe, evidenced by their different digivices, the fact that digimon apparently exist as a card game in their world and the fact that Takato told us about things that didn't happen in our world. I think Ordinemons presence extremely weakened the barrier between worlds, which would also explain why we got to the Digiworld so easily again." Izzy explains.
"Okaaay, but how did your encounter with Devimon go?" Davis asks.
"Not good" Tk answers while looking at Veemon, Hawkmon and Armadillomon "He used a lot of black gears to create copies of our digimon and escaped. But I see you got your partners back!"
"We got them back yes, but we were attacked by a Mega Level Digimon." Cody responds "Gatomon was almost defeated when Imperialdramon arrived to help, but luckily Henry helped."
"Oh, so that's why Gatomon is back on the Rookie Level" Tai notices while looking at Salamon standing next to Kari.
"We should definitely head back to the real world and gather the others" Izzy says "We need to meet up with the others and discuss our next actions. It seems like the Digiworld is in trouble again."
The group gets moving in the direction of the next gate into the real world when suddenly the ground begins to shake. The ground cracks open below Ken and Henry and they fall into a deep canyon. Calumon who sat on Henry's shoulder silently the whole time tries to jump up but falls down as well.
An unknown amount of time later.
Ken slowly wakes up in a dark cave with Wormmon laying next to him. Henry lays a few feet apart from him. Calumon repeatedly tries to slap Henry to get him to wake up, but it's small hands can't bring up enough force to do anything. Ken tries to shake him but he remains unconscious.
"Are you okay Ken?" Wormmon asks as it tries to move in Kens direction.
"I'm okay, I only got a few bruises. Are YOU okay?" Ken replies in a worried tone.
"I'm okay, I'm just exhausted from running away from some black gears before you came and fighting Gundramon." Wormmon says as it crawls into Ken's arms.
"You won't be okay for long" a mysterious voice says. A shillouete walks out of the shadows revealing a golden digimon with the design of a clock. It has mechanical arms and legs and an eye at the spot between the 12 and the 3. "Im Clockmon and my master wants you dead".
The clockmon shoots a yellow sphere out of the clock part of its body, encasing Ken, Wormmon, Calumon and Henry.
The energy sphere dissapears but instead of the cave that they were in before, they suddenly appear in a dessert. Ken can't see anything except a flying stone. Upon closer examination Ken recognizes the flying stone, it was the base he used when he was the digimon emperor. He stares at it until something he had hoped to never see again busts out of the base. It's Kimeramon, the digimon he created when he was the Digimon emperor, holding Magnamon in its hands. Behind it, he can also see Pegasusmon and a younger TK riding it. Suddenly Ken realizes something.
"This was three years ago" Ken says "The clockmon sent us back in time..."
"We need to help Magnamon!" Wormmon shouts as it jumps into Kimeramons direction but he is grabbed by Ken.
"No! We mustnt interfere! Who knows what could happen if we mess with the time line? Magnamon will defeat Kimeramon, we know that." Ken whispers in an attempt to not attract any attention. But it's too late Kimeramon drops Magnamon and flies in Ken's direction.
"Now it's too late" Ken says with panic in his voice.
[Wormmon digivolve to... Stingmon!]
Stingmon stands in front of Ken in a protective position. Kimeramon fires a blast of energy from its mouth knocking Stingmon to the ground but it quickly gets up to protect Ken. Kimeramon is about to fire another blast but suddenly Magna on appears and blocks the attack.
"I don't know who you are, but you need to leave. It's dangerous here" Magnamon tells Stingmon and Ken.
"No, we will help!" Stingmon replies.
Both digimon fly up in the air. Using Magna Punch and Spiking Strike, the two digimon attack from left and right respectively. Stingmon is knocked away by Kimeramons Skullgreymon arm while Magnamon is grabbed by its Devimon arm. Suddenly out of nowhere, the Worrmon of the past jumps from an Airdramon, hitting Kimeramon, freeing Magnamon and using its remaining life force to power it up. Meanwhile, Ken kneels next to the wounded Stingmon. He remembers that this was the day that Wormmon gave his life to defeat Kimeramon, the monster he had created. Ken wraps his arms around Stingmon as he fears to lose him to his own horrible creation again.
Calumon watched the whole thing while staying with the unconscious Henry. Saddened by Stingmon condition the red triangle on its forehead suddenly starts to glow and emmit a beam of light, flying right into Ken's digivice. Stingmons body starts to glow.
[Stingmon digivolve to... Dinobeemon!]
Stingmon now has a new appearance. His face stays the same as before but he now has blue antennas, two blue muscular arms and a blue tail. His posture changed from a humanoid position to a Insect like posture. He stands on two green legs with his arms hanging in front of them but not touching the ground. His wings grew larger and due to the changed posture are now on top of him like most insect digimon.
"He reached the Ultimate Level without ExVeemon! And he didn't digivolve to Paildramon!" Ken notices while being stunned by the sudden digivolution.
Magnamon lands next to Dinobeemon.
"Alright, wanna try this again?" The gold armored digimon asks.
Both digimon nod and begin to attack. Dinobeemon manages to fly behind Kimeramon with high speed and uses his now stronger legs to kick Kimeramon. The surprised Kimeramon turns around leaving its back now vulnerable to an attack from Magnamon. Magnamon uses his magna explosion to strike Kimeramon in the back with a powerful attack, defeating it. As Kimeramon is defeated the world around Ken and Dinobeemon begins to swirl and fall apart. Dinobeemon manages to grab the still unconscious Henry and Calummon before flying to the ground to pick up Ken. The world around them collapses and they suddenly find themself back in the cave.
"What? You managed to survive my time warp? Next time I'll come back with more of my kind and we'll trap you in the past permanently!" the clockmon shouts angrily as it runs away.
Before it can escape, Dinobeemon uses his attack "Hell masquerade" instantly defeating it. Dinobeemon flies out of the gap they fell trough to the surface where the rest of the group waits for them. As Izzy sees Dinobeemon he wants to ask about it before he is interrupted by Ken.
"No time to ask, I'll explain it later. Henry need to go to a hospital he has been unconscious for half an hour now."
The group nods as they rush to the next Digigate to get back to the real world.
Authors notes: No, Dinobeemon is not an OC. He is the Canon ultimate level of Stingmon. Should I ever use OC characters (which I probably won't because I try to stick with official digimon) I will mark them as such.
