The sun began to set over the hillside, the sky a pale shade of orange. The town behind the hillside shone as the lights began to flicker to life. A boy and a small creature sat at the edge of a forest, the soft fallen leaves being used for cushions as the two watched the sun sink.

"Master, what do we do now? I'm sleepy!" A red ball-like creature with four little legs had yawned. It had black markings on its body, a long tail, a pair of ears in the shape of bat wings, and large yellow eyes.

The young man with grayish-black hair and dark eyes patted the creature that sat in his lap on the head. The boy wore a blue shirt and a black jacket with blue jeans. He looked out to the sunset. "No worries, Gigimon. We'll head back home and go to bed."

Gigimon snuggled up to his Tamer. "Good! I love summer! We get to spend more time together, we get to go to new places, and most of all; we get to sleep in! No more seven o'clock alarms! Let's go, Will!"

The young man picked up Gigimon and walked away from the forest and towards the town. Gigimon dozed as Will carried him home.

...

Will was a Digimon Tamer, a human chosen by a Digimon to train them to become strong. Will, unfortunately, wasn't the training type. After three years with Gigimon, the young Digital Monster had grown very little.

The boy and his Digimon had arrived at a small, white house. A two-floor complex that the two called home.

"Mom," Will said as he entered the house, "We're home!"

"Are you two hungry? I made Gigimon's favorite Sticky Buns!" Will's mom had called out from the kitchen. She was the only person besides Will himself that knew of Gigimon's existence.

"No thanks, Mom," Will said, "Gigimon's fast asleep, so I'm going to put him to bed. Maybe later!" He then went upstairs to his room.

The bedroom was a bit boring, being a blank white color with minimal decorations aside from the mahogany nightstand and bed set. The walls had framed watercolor pictures hanging from them, art projects from Will's Art class. A computer on a wooden desk was placed in the far corner.

Will put Gigimon on his bed. He then went to his computer, sat down in his chair, and logged on.

A window appeared on the screen. It had a picture on a green worm on it. "What's this?" Will muttered out loud. Gigimon began to stir slightly.

The text in the window said, 'Do you have a Digimon?', and has two boxes marked 'Yes' and 'No' respectively. Will clicked 'Yes'.

The screen changed. It said, 'Is your summer boring?' Will click 'yes' again.

The screen changed again. It now read, 'do you want excitement?' Will said 'yes'.

It then said, 'Are you ready?'

Ready for what? Will thought. He clicked 'yes'.

The computer suddenly began to spark and crack. The worm picture began to wiggle. It then suddenly wiggled out of the computer screen. Will jumped away.

"What's all the racket?" Gigimon stuttered. He saw the worm and instantly started up.

"What is that thing?" Will asked. The green worm had a yellow underbelly and purple claws and a long purple stinger on its tail. It also had black electrical patterns on his back and face, which also had two long antennas and a purple beak.

"Dokunemon! It's a poisonous Digimon!" Gigimon said.

"Poison Powder!" Dokunemon yelled as it spewed powder from its mouth.

"Don't breathe it in! It's poisonous!" Gigimon said as it covered its mouth with its tail.

"Oh, really? Who would have thought a move called 'Poison Powder' was poisonous?" Will said sarcastically as he too covered his mouth.

"Poison Claw!" The larval Digimon lunged at the two, his claws glowing pink.

"Hot Bite!" Gigimon jumped at Dokunemon, dodging his attack, and sunk his small teeth into the worm's back. Dokunemon winced as he hit the wall behind Will. It then bashed Gigimon against the wall, knocking him off.

"Electric Poison Nightmare!" Dokunemon said as it shot a yellow-and-purple blast of energy at Gigimon. The red Digimon was knocked into the computer, which was still sparking copiously with black electricity. Gigimon squeaked in agony, and then fell silent.

"Gigimon!" Will yelled as he ran to his partner. The Dokunemon shot thread at his feet, causing him to fall. The evil Digimon chuckled.

"Gigimon..." Will said weakly. The thread was charged with electricity, which began to numb his body. He reached for his partner, calling him again, but there was no reply. Will closed his eyes in defeat.

Something fell into his hand. Will opened his eyes to find a strange watch in his palm. It was white with a screen in the middle, surrounded by a grey ring with strange symbols on it. He pressed a button on the side of the watch accidently, and the ring rose from the watch. Will pushed it back down with his other hand.

A beam of light shot out of the watch and hit Gigimon. The computer sparked again, shocking Gigimon as he began to glow.

"Gigimon Digivolve to..." Gigimon grew, becoming a large, lizard Digimon with bat-wing ears and long clawed hands and feet. He was jet black in color, with red markings on its body. A black crest resembling a biohazard symbol was on his white colored chest. "BlackGuilmon!"

The dinosaur Digimon smacked Dokunemon away from his Tamer and pulled the thread away from his legs. Will was speechless. His cute friend Gigimon had transformed into a huge, black monster. He was overjoyed.

"Pyro Grenade!" BlackGuilmon shot a dark purple sphere at the larval Digimon. Dokunemon screamed as the attack burned at his data.

BlackGuilmon dashed at Dokunemon with blinding speed. "Rock Crusher!" The black Digimon slashed the worm with his claws. Dokunemon gasped as its body get violently thrashed about by dark energy. The Evil Digimon screamed as he dissolved into bits of data. The data swirled and entered the watch in Will's hand.

"10 Data Points collected." The watch said.

BlackGuilmon helped his Tamer up to his bed. Will hugged him tight.

"That was awesome, Gigi, I mean, BlackGuilmon!" Will cried.

"Yep, I was great!" BlackGuilmon growled. He then slumped down to the ground. "I'm sleepy. Goodnight!" The black dinosaur began to snore on the carpeted floor.

The bedroom door opened. Will's mother rushed in. "What happened up here?" She looked around to see scorch marks on the carpet and walls, the computer in the corner sparking and flickering, and a large black lizard snoring on the floor. She gulped in shock.

"Mom," Will said nervously, "Meet BlackGuilmon, Gigimon's evolved form. Hope you don't mind the redecorating we did. By the way, we might need a new computer."
