>>12790478It really depends on which fans you're talking about.
Sonic fandom encapsulates the whole deal whereas Pokémon is generally divided between nostalgiafags, the anime fans, the gamers, perverts (which are generally two groups of either porn of humans or Poképorn and a third that overlaps betwixt the two) and competitivefags.
The only real similarities it shares with Sonic fandom would be furbait and maybe touting on series as the MOST true (like how Archie fags swear up and down the Sonic comics should be the stories just as much as some PokéSpecial/Adventures fags insist it's definitive story of Pokémon)
