Kinnikuman: Muscle Fight/WMG

Something is causing the various continuities to blend together
Normally, it's impossible for Dirty Baron to fight anybody from the Scramble from the Throne arc, for Kinnikuman characters to fight their counterparts from later on in the Kinnnikuman storyline, or for the Kinnikuman Nisei characters to fight Choujin in their prime. Something big is messing with the timelines and causing them to fuse into one big mess.

Guesses:

 * A Time Crash
 * Certain characters undergoing a Groundhog Day Loop and reliving moments of their lives.
 * Time Choujin pulling the strings behind the scenes.

Future Characters made by Matayan

 * Parthenon
 * The other members of the Perfect Origin
 * The other Perfect Large Numbers.
 * Pandaman
 * Kevin Mask
 * Seichuin
 * Terry the Kid
