A/N This is in response to Bluemew22's Concepts Challenge. The rules are (1)In the alternate time stream the challenger constructs, if the events are set after Phantom Planet, the Disasteroid can have happened, but Danny can't be revealed. (2) Where Danny has ice powers, Jazz's special power involves her intellect somehow. Mine is going to have no PP, so hope you enjoy! And Bluemew22 hope you read it! I don't own Danny Phantom or this Challenge.

Jasmine "Jazz" Fenton, now 17 years old, walked around her house looking for her 16 year old brother Daniel "Danny" Fenton. Jazz knew her parents were gone for the week and she was in charge of Danny, "Danny!" Jazz called for the 10th time that day.

Suddenly, she heard a grunt come from the lab. She felt her heart stop and ran downstairs to the lab, "Danny!" Jazz yelled.

"Jazz! No! Go back upstairs!" Danny yelled at his older sister.

Danny was in Phantom form fighting, once again, Skulker, Ghost Zone's Greatest Hunter. Danny got hit with one of Skulker's new rays and turned human, "Danny!" Jazz yelled and ran over to her little brother.

Danny grunted in pain, "What was that?" Danny weakly asked Skulker.

"My new Whelp Ray," Skulker said smirking, "Can cause you so much pain you turn human."

"Danny?" Jazz asked.

"Get out of here Jazz," Danny said weakly.

Jazz remained stubborn and didn't moved. She looked at the portal, "How'd you even get in here? The portal's off," Jazz asked Skulker.

Skulker laughed, "I've been out of the Ghost Zone for two days waiting for the perfect time to attack the Whelp."

Jazz glared at Skulker, "Why can't you just leave him alone!" Jazz yelled.

"Jazz, please get out of here," Danny said back at full strength.

"You should listen to your little brother," Skulker said and shot a ray at her.

"Jazz!" Danny yelled.

Jazz gasped and quickly jumped out of the way of the ray, but the ray cut some of her hair making it just above her shoulders, "Hey!" Jazz yelled.

"Danny!" Sam and Tucker yelled as they reached the lab.

Danny transformed, "You three need to get-" Danny's sentence was stopped when Skulker grabbed his neck.

"Danny!" Sam, Tucker, and Jazz yelled.

Sam was the first to attack Skulker, "Let him go!" Sam yelled.

Skulker laughed and threw Sam into the wall, "Ah!" Sam yelled.

"Sam!" Tucker and Jazz yelled.

Sam groaned and then Tucker tried, but got knocked into glass beakers and tubes, "Tucker!" Jazz yelled.

Skulker laughed, "You going to try know girl?" Skulker asked.

Jazz growled and ran at Skulker, but got thrown into the portal, "Ha ha," Skulker laughed, "Is this the best your little team can do Whelp?"

Danny growled and kicked Skulker, "No one hurts my friends and family!" Danny yelled at Skulker.

Jazz held her head in a daze. She looked and saw blurry figures of Sam, Danny, and Tucker fighting Skulker, 'I have to help,' Jazz thought.

'No, you'll just get in there way like always,' a voice said.

'Maybe you're right,' Jazz said to the voice and looked at her little brother and his two best friends, 'All I do is get in there way.'

"Let's see how you sister likes a little shock," Jazz heard Skulker's voice say.

Jazz's eyes went wide and looked at where she was. She turned to Skulker and saw him holding the plug to the portal, "No!" Danny, Sam, Tucker, and Jazz yelled.

Jazz tried to run out of the portal, but Skulker plugged it in before she could get out, "Jazz!" Danny, Sam, and Tucker yelled.

Jazz ran out of the now on portal and fell to her knees, "Jazz!" Danny yelled and turned human and ran to his sister, "Jazz? Jazz can you hear me?"

Jazz opened her eyes and looked at her worried brother and two friends, "Danny? Sam? Tucker?" Jazz said weakly.

"Jazz, are you alright?" Danny asked.

Jazz sat up, "I think so," Jazz said.

It was then Jazz noticed she was glowing. Jazz gasped, "Danny, I'm I…"

Danny just nodded, "I'm sorry Jazz," Danny said, "It's my fault. I couldn't stop Skulker."

Jazz looked at herself in the mirror in the lab and went wide eyed. Her red-orange hair was now a dark white, almost gray and came down to just above her shoulders and her eyes were now green, but lighter than Danny's in Phantom form. Her light blue tank top with a black heart in the middle was now a light purple and the heart a dark purple and her blue jeans were a dark purple and her light blue flats were now black, "Jazz?" Jazz heard Sam asked, "Even though I love the outfit, are you okay?"

"I-I'm not sure," Jazz said, "This is a big shock."

"It was for me too," Danny said, "See if you can turn back human."

"How?" Jazz asked her little brother.

"You'll have this feeling in your stomach when you find it," Danny explained.

Jazz nodded and closed her eyes. Suddenly, a teal color ring appeared around her waist making her gasp in surprise. The ring went up and down changing her back to Jazz Fenton, "Whoa," Jazz said.

"Do you want our help so you can control your powers?" Danny asked.

Jazz nodded, "That might be best because with two Halfas in the house the inventions are going to go crazy and you know how I am under pressure."

Danny, Sam, and Tucker nodded, "We'll start now since mom and dad are gone for the rest of the week," Danny said transforming and helping his sister off the floor.

Jazz nodded and transformed as well, "Where do we star-ah!" Jazz said as she suddenly phased through the floor.

"Tangibility," Danny yelled through the floor.

Jazz poked her head through the floor then her whole body, "No need to yell Danny," Jazz said.

Danny laughed, "Okay, to control tangibility you need to…"

A/N So how does it sound so far? R&R.
