I removed it because it was abit disorienenting compared to other pages since we generally classfy them being under the same series, especially after All Stars now being canon. If you wish to indicate which season he came from, you can always use brackets next to the link page, like this: Origin:Pretty Cure (Suite Pretty Cure).
Since you are a discussion moderator and the one who created King Boo's page, I wanted to contact you about him being listed as having infinite stamina. In the Mario series, ghosts don't have infinite stamina. Mr. Luggs is shown to have poor stamina despite being a ghost. King Boo should have his stamina changed to high or something, and the justification of him being a ghost should be removed since Luggs is proof that ghosts can have poor stamina in the Mario series.
Mr. Lugg "poor stamina" is just a parody of how easily overweight people tire out from simple tasks. Plus, it's completely contradicted by the fact after his death, he still continously eats without being satisfied or slowing down. King Boo himself also never express this weakness, hence why it remians the way it is.
