A/N, Post PP. Dani was never created, cloned, i don't know, anyway enjoy.
Danny was about to leave to Sam's house. It has only been about 3 days since they got rid of the disasteroid and up to today, he has rested. No one but Sam, Tucker, Jazz and his parents have seen him yet. Danny decided it was about time he got some exercise. He told his parents that he was leaving, they told him bye and he opened the door. THUD
Instinctively, Danny let two rings form around his waist. Seconds later, Danny Phantom stood in his place. He looked down to where the THUD came from and saw a little ghost. She was smaller, but still looked about 14. The weird thing was, she looked just like a female Danny. She had a Ponytail tying her long-ish, Snow white hair back, She wore white and black pants and a black and white shirt. On the black part of her shirt was a white D. The same D from Danny's DP sign.
The girl looked up towards her attacker. Skulker. The girl had not yet noticed Danny as she got back to her feet. She flew up to Skulker, firing a large Ecto-blast at him. She then pulled out a thermos. WAIT… A FENTON THERMOS, thought Danny. This little girl aimed the thermos at Skulker, shot a blast out of it and sucked him into the thermos. She landed on the ground and took a deep breath.
Danny came out of his hide-e-hole and walked to the little girl. "Hi," He mumbled. She gasped, but then calmed down a bit. "Hi," she replied. "I'm Danny, Danny Phantom." "Hi, nice to meet you Danny," said the girl. "Can you tell me your name," continued Danny. "I'll tell you my name when you tell me your human one."
Right then and there Tucker and Sam came running towards the house. "Tuck, Sam, get over here," yelled Danny. "Ok," they yelled back.
"Danny what are you still doing here? What was all that ye… GHOST," His mother, Maddie Fenton screamed as she wondered from the Fenton works.
"What, Ghost, where?" Out came his father, Jack Fenton.
"I heard there was a ghost", was said as Jazz wondered out.
"What is your real name, trust me, it is important, all I know is that you are half ghost, who is you human half. I need to know, KNOW," the ghost girl started to cry.
"Danny, tell her," Sam said sweetly.
"And what are the full names of all the people here," The girl mentioned.
"Ok, ok. I'm Danny Phantom, AKA Danny Fenton. My mother, Maddie Fenton. My father, Jack Fenton. My sister, Jazz Fenton. My Best Friends, Sam Manson and Tucker Foley." Said Danny.
"Now transform, please," The girl said crying a lot harder. Two rings formed around Danny's waste as he was once again Danny Fenton. The girl was now full on balling on the floor.
"Stop Crying, and WHO ARE YOU," yelled Jazz. "I'm, I'm, *tear* your sister. It's me, Dani, Dani Phantom." She let two rings forms around her waist as she continued, "Also, Dani Fenton."
