Honestly, I can't even tell if you're trolling or being plain stupid with these remarks.
Comparing G&W, Jigggs, and Ness to Pichu is such a horrid comparison, as all of them offer more than Pichu.
- G&W represents the G&W series and is not a clone.
- Ness represents Mother and is not a clone and is an original.
- Jigs is a popular Pokemon character and not a clone and an original.
Claiming Pichu's repping of Baby Pokemon as being a valid reason to back him up is ridiculous, espiceally when there are many other pokemon who rep more important aspects of Pokemon, such as Meowth (Anime) or Togepi (Anime) or Mew (Event Pokemon) or Eevee (Stone Evolutions) or , using the opposite of your own logic. Raichu (Adult Pokemon).
Not to mention there are far more popular pokemon than Pichu, like Gengar, Gardevoir, the previously mentioned Meowth, Blaziken, and Sceptile. And, news flash, DLC characters need to at least be moderatly popular in order to get good sales.
