The EDD returned to the castle later and went to see Enfernomon.

"How did it go?" Enfernomon asked the EDD.

"I did great. All of our digimon went to the champion level, plus we destroyed Monzaemon and Toy Town. There was no interference." Lance told Enfernomon.

Enfernomon nodded his head. "Hmmm... I wonder why that digimon didn't interfere, like when he killed Sphinxmon."

Enfernomon waved the EDD off, and the EDD turned around and walked away.

Megakabuterimon landed in the middle of a forest and the Digi Destined jumped off of him. Megakabuterimon turned back to Tentomon. As usual, Izzy sat on the grass and turned on his laptop. He clicked a few times, and came onto a map of where they presently were.

"We're extremely close to Enfernomon's Castle. We could go in and destroy it. But that would mean that we'd have to face either Darknexismon, Enfernomon, or the EDD." Izzy thought out loud.

"Quite true, but too bad you'll never get there" a voice said.

The Digi Destined looked around wildly, and found Ultimon, a skinny knight-like digimon with a cape surrounding its body, hovering over a tree.

Izzy instantly checked his computer for a profile on Ulitmon. "That digimon is Ultimon. A mega digimon capable of disintegrating anything with its Sword Wave attack."

"Right, brainiac," Ultimon chuckled. Ultimon landed on the ground in front of the group. "Now, lets battle."

Tai and Matt nodded.

"Agumon, warp digivolve to... Wargreymon!"

"Gabumon, warp digivolve to... Metalgarurumon!"

Tai and Matt turned to the others. "Let us handle this. Your digimon could get hurt if they went into this fight." Tai told the others. The others understood and watched the battle, ready to get in if Ultimon took out Wargreymon and Metalgarurumon.

Wargreymon flew at a very low altitude after Ultimon. Metalgarurumon ran after in back of Wargreymon. "Mega Claw!" Ultimon leaped into the air before Wargreymon could swipe him. Wargreymon just swatted dead air. Ultimon came crashing down, right onto Wargreymon's back. Ultimon pinned Wargreymon with his weight. However, he didn't see Metalgarurumon run at Ultimon. Metalgarurumon ran into Ultimon and tackled him through a tree. Metalgarurumon now pinned Ultimon on the ground, and was mauling him. Ultimon blocked Metalgarurumon's bites with his sword, which was attached to his side. Ultimon managed to kick Metalgarurumon off of him. Metalgarurumon landed swiftly in front of him. Metalgarurumon ran after Ultimon again, but Ultimon was ready.

"Sword Wave!" Ultimon slashed in a horizontal direction with his sword, creating a wave of energy which rippled the air when the wave passed it. The wave caught Metalgarurumon head on and sent him flying towards Wargreymon, who was just getting up. Wargreymon saw Metalgarurumon coming, and ducked as Metalgarurumon sailed over him into a tree. Wargreymon took to the air and flew after Ultimon. Ultimon ascended into the air, closely followed by Wargreymon, who was trying to swipe him with his Mega Claw. Ultimon stopped suddenly and Wargreymon flew faster at him. Ultimon brought up his sword and blocked all of Wargreymon's swipes.

"Metal Wolf Claw!" A beam of ice shot at Ultimon out of no where. Ultimon was too busy with Wargreymon to see the blast coming. The blast hit Ultimon head-on onto Ultimon's chest, narrowly missing Wargreymon. Ultimon grunted and flew backwards towards Enfernomon's Castle. Ultimon smashed through a stain-glass window, onto the carpeted floor of the castle. Wargreymon flew in, followed by Metalgarurumon. Ultimon faced his two foes.

"Give it up. You've lost." Wargreymon told Ultimon.

Ultimon shook his head. "Not yet. Sword Wave!"

"Skull Missile!" A voice shouted out of no where as a missile like Metalgarurumon's Giga Missile, but a bone, shot through the sky and exploded onto Ultimon, instantly vaporizing him.

The Digi Destined looked up and saw that same digimon that killed Sphinxmon. The digimon shot past Wargreymon and Metalgarurumon and flew further into the castle.

Izzy closed his laptop. "Darn, he was too fast for me to get a reading."

"Trust me, Izzy, I have a feeling we'll meet again. He has the same goal as we do." Tai said.

"I hope you're right, Tai," Kari said.

Wargreymon and Metalgarurumon jumped out of the hole in the castle and landed on the ground next to the Digi Destined. "Come on, let's go." Wargreymon said. Tai, Kari, Sora and Izzy went into Wargreymon's arms and he flew up to the hole in the castle. The others got on Metalgarurumon and he followed Wargreymon up.

Enfernomon, seeing the latest happenings on a bubble like which Darknexismon used, was furious. "Who is that digimon and why does he keep killing my servants?!" Enfernomon asked no one.

A digimon next to him which looked very much like Gigadramon and Megadramon, but his whole body was metal plated except for his ripped crimson wings, sighed. He had no idea who the digimon was. "Well, master, by the looks of it, if that digimon killed Sphinxmon and Ultimon with ease, then I'm guessing he's an ultra."

"Maybe so, Metaldramon." Enfernomon walked out of the room, leaving Metaldramon.

Once inside, Metalgarurumon and Wargreymon de-digivolved to Agumon and Gabumon. They walked around aimlessly for a moment, until they reached a door. They opened it slowly. As soon as the doorway was fully open, Mimi shrieked to see Darknexismon facing them.

"Well, isn't this a surprise. The Digi Destined came to see me. Thank you, it saves me the trouble of finding you." The digimon guarded their partners in case Darknexismon did attack. "Dark Blade!" A beam from his blade flew at the digimon. The digimon yelped as the beam hit them. They flew back, into their partners. The Digi Destined flew along with their digimon through the wall of the room, then smashing through the wall of the castle, causing them to fall towards the water. Darknexismon peered over to watch the Digi Destined fall in the water, then the water carrying them upstream. "Well, that was easy. Take care, Digi Destined." Darknexismon started to laugh.

Metaldramon started to make the bubble disappear. Suddenly, a crashing sound was heard behind him. He turned around to see the digimon which killed Sphinxmon and Ultimon. Metaldramon tried to hold back his fear of the digimon. "What do you want??" Metaldramon asked the digimon. The digimon said nothing and quickly flew after Metaldramon, tackling him through the wall, into mid-air. "Fine! If you are trying to delete me, you'll just have to put up a fight first."

The digimon still said nothing. However, he stopped and backed off a bit. Metaldramon tilted his head at the sudden occurrence. He was sure the digimon would finish him off there. "Skull Bone Claw!" A sharp bone flew at Metaldramon at amazing speed. Metaldramon descended a bit and ducked the attack.

"Metal Darkside Attack!" The missile pods on his hands opened, launching silver missiles. The missiles connected against the digimon's body, but it seemed to have no effect. The digimon chuckled a bit and flew after Metaldramon again. Metaldramon quickly descended under the digimon before it could tackle him. Metaldramon raised his left pod and smashed into the digimon's underbelly. The digimon softly grunted a bit in pain. Metaldramon smiled as he just figured out his strategy. Metaldramon was too distracted to see the digimon kick him with his back legs. Metaldramon flew back and kept flipping around in the air, careening towards another wall of the castle.

"Skull Missile!" Another missile launched out of the digimon's body at Metaldramon. The missile rammed into Metaldramon's right arm and exploded on impact. Metaldramon yelled in pain and smashed through the wall of the castle.

Moments later, the digimon looked to see if there was any movement from Metaldramon. There hadn't been since. Satisfied, the digimon flew back into the castle.

Enfernomon had heard the sounds of battle that seemed to be outside. He ran through the hall he was in, and stopped to see Metaldramon unconscious on the ground. In front of him was a hole in the wall. Enfernomon stopped by Metaldramon and peered at him. Metaldramon woke up.

".....mmaster? Its that digimon......the one that killed Sphinxmon and........Ultimon.....Uhhh......" Metaldramon went back into unconsciousness.

"How did that digimon come here?! I've got to destroy that digimon before it causes more trouble." Enfernomon turned around and ran down the halls.

"Skull Missile!" An all too familiar voice yelled. The missile careened through the air and smashed into Enfernomon's left leg, forcing Enfernomon to thud onto the ground. Enfernomon glanced up to see the digimon looking down on him.

"It's you!" Enfernomon yelled as he jumped to his feet.

"Yes. I've been waiting for this encounter, Enfernomon." The digimon spoke. "Allow me to introduce myself. My name is Skullmetalgarurumon. I've been ordered to destroy you."

Enfernomon eyes widened. "Ordered? By who?"

"By me," a voice said. Darknexismon stepped out of the shadows.

"Darknexismon?! Why?!"

"My goal is to conquer the Digital World. By having my servant, Skullmetalgarurumon, destroy you, I can conquer the Digi World without having to babysit you and your puny Evil Digi Destined. Now do it, Skullmetalgarurumon." Darknexismon ordered. Darknexismon turned around and walked away.

"Orders are orders." Skullmetalgarurumon said. "Without you, my master can easily conquer the Digi World. Skull Bone Claw!" A bone flew at Enfernomon. Enfernomon easily jumped over it and he quickly put his hand into his fiery torso.

"Inferno Ball!" Enfernomon drew back his hand which was clutching a fireball. Enfernomon threw the ball at Skullmetalgarurumon. The ball hit against Skullmetalgarurumon, forcing him into a wall. Enfernomon ran up to him and placed his foot over Skullmetalgarurumon's throat. "I, too, am an ultra level digimon. You cannot easily defeat me as you did with Sphinxmon and the others."

"Wanna bet?!" Skullmetalgarurumon said as he raised his head quickly, tripping Enfernomon. "Skull Blade!" Skullmetalgarurumon withdrew a sharp bone from his body and jumped at Enfernomon with it. Enfernomon raised his arms and caught Skullmetalgarurumon, and using momentum, was able to throw Skullmetalgarurumon into another wall.

"Inferno Ball!" Enfernomon threw the ball at the stunned Skullmetalgarurumon. He saw the ball coming and jumped over it.

"Skull Missile!" Two missiles left Skullmetalgarurumon and both exploded onto Enfernomon's face. Enfernomon yelled in pain and backed away. What he didn't know, was he was backing up into a hole in the castle. Enfernomon fell, but caught the rim of the floor. Skullmetalgarurumon trotted over and stopped by the hanging Enfernomon. "Now who's the one about to be deleted?" Skullmetalgarurumon asked. Enfernomon didn't answer. Skullmetalgarurumon smirked and grabbed Enfernomon's hands and he forced Enfernomon off the castle. Skullmetalgarurumon let go and Enfernomon plummeted to the ground below. Skullmetalgarurumon stood on his hind legs. "Skull Missile!" A missile left Skullmetalgarurumon's underbelly and flew towards Enfernomon. Suddenly, Enfernomon glowed with an orange and red glow. The missile connected into Enfernomon, but instead of exploding, Enfernomon absorbed the missile!

"That's it, Skullmetalgarurumon! Enfernomon, digivolve to..." Enfernomon grew bigger and taller. His fiery torso disappeared and he assumed a humanoid shape. His crimson limbs became pitch black, as did his torso. His arms ended in huge crimson claws. A pair of red decaying wings, which were on fire, shot out of his back. His head became a skull set on fire. "...Infiernomon!" Infiernomon's wings flapped in the air and Infiernomon landed back on the castle in front of a bewildered Skullmetalgarurumon. "What were you saying, Skullmetalgarurumon?! Nova Claw!" His claw became on fire and Infiernomon slashed Skullmetalgarurumon. Skullmetalgarurumon yelled in pain and smashed through the wall on the other side of the hallway and plummeted into the water. Infiernomon watched Skullmetalgarurumon struggle to stay afloat in the water. "Time to die, Skullmetalgarurumon! Hell's Welcome!" Infiernomon raised his arms to the air, and the ground beneath Skullmetalgarurumon rumbled. A geyser of molten lava shot out of the water, taking Skullmetalgarurumon into the air.

The geyser stopped a few moments later and Skullmetalgarurumon fell into the hole in the ground which the geyser originated from. The ground covered over the hole, encasing Skullmetalgarurumon forever...
