Quadtoon is a low chance FanFiction in the work. Strictly ideas and fantasy of my mind only. If I were to create this fan fiction I would Need to watch and rewatch each of the series. Very time consuming and with my current agenda, nigh chance of not happening.
Although a low possibility, here is the rough outline for how I would make the series. The Trilogy of you want to call it.
Kim Possible x American Dragon : Jake Long x Danny Phantom x Randy Cunningham 9th Grade Ninja
Series 1 - S2 KP, S1 ADJL. Finale - Glitch in time
Series 2 - S3 KP, S2 ADJL, S1DP. Finale - So The Drama x Homecoming
Series 3- S4 KP, FanMade S3ADJL, S2 DP, S1 RC9GN. Finale - Graduation x Ultimate Enemy x 13th
I have not watch Randy Cunningham 9th grade ninja all the way through. Only the first, probably less, than season one around the time it came out. Just finished skim watching American Dragon Jake Long. Have seen Kim Possible a couple times all the way through but half a decade ago. Watched up to season 3 of Danny phantom a year or two ago.
Glitch In time would have a future Shego and Dark Dragon. Foreshadow to Hong Kong events.
So the drama x Home Coming would replace the robot boss with the Dark Dragon? undecided .
Graduation x Ultimate Enemy x 13th would have my version of the Ultimate Enemy: half ghost half dragon: Danny Long, Jake Phantom. If I can work it. Unsure how I'll incorporate the three events into one. Also undecided.
