Chapter 1:
In Greece, a griffon, a minotaur, and a chimera were causing trouble. DNAmy was watching.
"Is it worth the destruction of a poor defenseless town just to make magnificent creatures," Amy asks herself, "why not?"
"We have some complaints, Amy," says Kim as she and Ron show up.
"Kim Possible," asks Amy.
"And boyfriend," says Ron.
Amy just stares. "I know, what's your point?"
Kim and Ron look at each other.
"Amy, Ron and I weren't dating before," says Kim.
"You weren't? Huhh, I thought you were. I mean if you weren't, then wow, you two were close."
"Y'know, I never thought of that before," says Ron, "hey, I thought you made yourself a gorilla lady?"
"Oh, I turned back when I learned gorilla hands and feet were not the best idea."
"Yikes," Kim and Ron both said.
"So, how did you know this was me anyway," asks Amy.
"Three amalgams from Greek Mythology," says Kim.
Amy slaps herself. "That was obvious! Well, I guess there's nothing for me to do but... ATTACK!"
The Griffon, Minotaur, and Chimera then attack Kim and Ron while Amy runs.
...
Amy runs to an ally.
"Even Kim Possible can't beat..." Kim and Ron then show up, both looking exhausted from fighting Amy's creatures. "Fiddlesticks."
"Now, we're taking you in, Amy," says Kim.
"Y'know, normal parents and teachers would never let you two do the things you do. What is wrong with yours?"
Then a jack-o-lantern appears.
"Is it Halloween already," asks Ron.
Kim walks closer to it, and it explodes, knocking Kim and Ron down. Then a strange hook comes and grabs Amy.
...
Amy wakes up.
"Where am I? What day is it? Of course I didn't lie about my age!" Amy then looks around. "Junior? Motor Ed? Gill? Seagull?"
"UUUUUUUUUmmmmmmmmm, the name is Shego."
"Oh, I always thought it was Seagull. I thought it was weird you were not bird themed in anyway. So, what am I doing here?"
"Why you were rescued... by me!"
"The g... g... g... g..."
"G... G... G... Green Goblin!" The Green Goblin then laughs while Amy screams.
"W-why am I here, Mr. Goblin, Sir?"
"I have grown tired of losing to a certain wall-crawler, so I decided to recruit foes he has not seen before! How would you and your twisted experiments like to join my team?"
"Umm... I appreciate the rescue, but I'm not too sure."
"Don't be stupid," says Gill.
"Yeah, this is the Big Leagues, Seriously," says Motor Ed.
"But he's scary," says Amy.
"But he has a sweet Glider," says Junior, "thought it might mess with my hair if I tried it."
"We wouldn't want poor Amy to be uncomfortable, would we? You are free to go."
"Oh, thank you for understanding, Mr. Goblin."
"My pleasure, but I want you to leave with a special gift." The Green Goblin then throws a pumpkin bomb to Amy and when the Goblin and his gang leave, the bomb explodes.
"I'm still alive," says Amy, "but I am seriously hurt!"
"I said she was free to go," says the Green Goblin, "I didn't say she wouldn't get hurt!" The Goblin then laughs while his gang are a little uncomfortable.
This is Non cannon to the Ultimate Advanceverse. For the record, I'm using the 90's version of the Marvel characters.
