A/N: Hello, this is my second story I am writing. However, unlike my last story, this one isn't a Johnny Test crossover. Also, I do not own Johnny Test.

I hope you enjoy, and be sure to review!

It was a Friday afternoon when Johnny got off the school bus in front of his house, carrying his backpack and a large stack of textbooks and papers. Dukey was waiting for him while sitting beside a shrub.

"You got homework-slammed by Mr. Teacherman again?" Dukey asked, seeing the big stack of books and papers.

"No," Johnny replied. "More like homework-bombed."

Johnny walked into his house and went upstairs to his room while Dukey followed him. The first thing he saw was a robot that grabbed all of his homework and completed it within a matter of seconds. Everything else in his room he saw was a plasma TV, a hot tub, and new video games.

"My sisters want something," Johnny said.

"I can almost guarantee that it has to do with Gil or Eugene," Dukey said.

Johnny and Dukey walked to the lab and entered.

"Can you invite Gil so he can hang out with us?" Susan asked.

"Then Gil will say, 'Sure, Johnny bro,' and he will come over," Mary said.

I was right, Dukey thought.

"No," Johnny responded. "I'd rather do something else."

"But we just made you a plasma TV, a homework-helping robot, a hot tub, and we bought you new video games," Susan said.

Johnny did feel a little bit guilty. "Okay, fine."

After he said that, his sisters hugged him. "Thank you, Johnny!"

"Let's just get this over with," Dukey said.

Johnny and Dukey walked out of the lab, out of the house, and then to Gil's house. Johnny knocked on the door, and after a moment, Gil opened the door.

"Oh, hey, Johnny bro, how's it going?" Gil said.

"Would you like to hang out at my house?" Johnny asked.

"Sure," Gil responded. "Because I would like to show you my awesome electric guitar skills."

Johnny was surprised; he never knew an interest of Gil was playing an instrument. "You can play that?"

"Yeah, I've been practicing for a long time."

If there's anything that Gil smart at, it is anything that has to do with music.

Johnny, Dukey, and Gil walked to Johnny's house and Gil rang the doorbell.

Johnny's dad answered and he looked at Gil. "What are you doing here?"

"Johnny invited me," Gil responded.

"Okay, come in, but don't break anything!" Johnny's dad warned.

The three walked into the house. "We're going to the lab," Johnny told Gil.

Then they walked upstairs to the lab and entered through the automatic door. Susan and Mary looked back to see Gil.

"Hey, girls I've never seen before," Gil said.

"No, you actually have seen them before. Many times before. They're my sisters," Johnny said. "Anyways, here's Gil."

"Thank you, Johnny!" Susan and Mary said.

Awkward silence.

"Why aren't you leaving?" Susan asked. "You usually leave after you do something for us."

"Because Gil wanted to show me something," Johnny replied.

"What is it?" Mary asked.

"I play the electric guitar; I'm going to preform," Gil said.

Susan and Mary's already high interest in Gil spiked to a new high. "This is something we have to see," Susan said.

"Can you play a song through those speakers you have while I'm playing?" Gil asked, pointing to the speakers.

"Of course," Mary said. "What song do you want to play along with?"

Gil said the desired song, and then Mary set everything up.

"Alright, push play after I say 'four,'" Gil said. "One, a-two, one, two, three…wait."

"What?" Johnny said.

"I forgot my electric guitar amplifier and the cords for that at my house," Gil said. "Let me go back and grab it."

Gil walked out of the lab, and after he did, Dukey said, "Seriously?"

SIX MINUTES LATER

Gil went back into the lab, carrying his amplifier and his cords. He set them on the floor, plugged the amplifier's cord into an electrical outlet, and then plugged in the cord that goes both into the guitar and into the amplifier. He switched on the amplifier and turned the knob labeled "Master Volume."

"Are you ready?" Susan asked.

"Yeah. Start after I say 'four,'" Gil said. "One, a-two, one, two, three, four."

Mary started the song and Gil played along. The song started off being moderately slow (81 beats per minute)—which was really easy for Gil—but when the song got to the guitar solo part, the song sped up to 197 beats per minute. Not only that, the notes Gil was dealing with were mostly eighth and sixteenth notes, with sixteenth rests in between. However, Gil didn't mess up; he played through all of that flawlessly.

"Whoooaa," Johnny, Dukey, Susan, and Mary said.

Then the song ended with a fading outro that was at 81 beats per minute.

"That was amazing!" Susan said.

"Best performance I've ever seen," Mary said.

"Yeah, Gil, you rock!" Johnny said.

Then some menacing-looking guy in a dark blue, metal suit and a helmet that covered his whole face (similar to Dark Vegan) busted through the ceiling of the lab. Everyone's eyes widened.

"Best performance? Amazing? Gil rocks?" the menacing-looking guy said with a deep voice. "I am Lethal Note, and nobody plays better than I do!"

"Uhh…okay…and you just busted through the ceiling. You're going to have to pay for that—" Johnny said.

"Shut up, flame boy!" Lethal Note said.

"Hey, don't tell our little brother to shut up," Mary said.

"You shut up too, you ugly nerd," Lethal Note said angrily.

Dukey tried not to say something out of anger. So did Susan, but she failed.

"Says the one in that ugly suit, a.k.a. Lethal Jerk," Susan said.

Lethal Note pressed a button on his suit, and a large laser gun came out of the left arm of the suit. He aimed it at Susan.

"H-hey, your suit i-is amazing, Lethal Note," Susan said with fear.

"Anyways," Lethal Note said, putting the gun back into his suit by pressing the same button. "I challenge you"—he pointed at Gil—"to a guitar battle later. If I win, you are going to be wiped out, you unintelligent, unskilled little piece of waste of space. If I win, I'll be wiped out too, but that will never happen!"

"Why would it kill me if I lost?" Gil asked.

"Because my guitars that I design forcefully blast the loser of the battle," Lethal Note responded.

Lethal Note flew away, going through the hole he made, evilly laughing.

"Man, I hate that moron," Dukey said.

"Are you scared of Lethal Note?" Mary asked Gil.

"Nah," Gil responded. "He doesn't know what he's talking about. Also, I can win this easy battle with no problem."

"Are you sure?" Dukey said. "I don't think we should underestimate Lethal Note. He seems pretty serious."

"Yeah, Gil is sure, duh! Like I said before, Gil rocks," Johnny said.

"Oh, I have a bad feeling," Dukey said.

Susan changed the subject. "Gil, can you play some more?"

"Sure," he responded. Then he played more.

Johnny, Susan, and Mary were having an awesome time, especially Susan and Mary. On the other hand, however, Dukey was not; he was anxious.

Lethal Note flew for a while until he reached his secret underground base. He descended to the ground, looked around, then entered.

"Assistants," Lethal Note said.

Lethal Note's assistants directed their attention towards him. "Yes, sir?"

"I will be battling this dude who thinks he can play better than I can. It will be an easy battle, but just in case, monitor me on that computer. If you see me losing—which is highly unlikely—then send in the Mega Metallic Robo-Musician of Music Note Death that will help me blast his butt with its unbeatable guitar skills," Lethal Note said.

"Yes, sir," the assistants said.

Lethal Note turned around. "Nobody, and I mean nobody, beats the best-of-the-best guitarist. That unskilled idiot will be done for, and nobody can stop me!" Lethal Note said to himself before evilly laughing.
