>>57387227you grossly overestimate the difficulty of beating a Pokemon game with one Pokemon
X items are really good and can make any shitmon a God.
I don't really have anything that can prove that I did all of these fully, only an unedited video of a playthrough could prove that, which I don't have. I do have many screenshots showing my progress through a game, such as pic related, showing my Emerald team after the sixth gym.
I am not sure what you mean by 'stats'
The in game playtime of certain games are displayed in the compilation screenshot. Also the moves level and HP are displayed in the Pokemon Colosseum screenshot. Not sure what else you would want in that department.
I do actually have some footage of my Delcatty Struggle Only run of Colosseum but I never uploaded it because I didn't want to edit a video.
I beat every official game using only one Delcatty (minus HM slaves obviously)
For fangames, some have level caps + increased Difficulty that make certain sections almost impossible/impossible for one Skitty/Delcatty so I used some back up dancers to help me with those parts. But you can beat the Pokemon League with one Delcatty for all of the games displayed, since by that point in the game you have all the tools you need for Delcatty to handle almost any encounter.
