• Bubapedia: PokeSpe page on Bulbapedia
• CorocoTV PokeSpe 🇯🇵: Seems like a site to commemorate the 20 years of Pokémon
• Pokemon Special 🇯🇵: Official PokeSpe site
• r/pokespe: Pokespe subreddit
• Pokecharms: Pokémon trainer card maker
• Pokeencyclopedia: cool Pokémon encyclopedia also has sprite resources
• Ultimate Favorite Pokémon Picker: not really Pokespe but a cool site anyway

It's really hard to find PokeSpe content without stumbling upon a site about the Pokémon games only, so if you know about anything not listed here feel free to contact me!
