I didn't see a thread on this (or, if there is one, it's really old), so please forgive me if I accidentally made a new thread for something that already has one.
It's fun to ship off the humans of Pokémon, but what about the titular creatures themselves? Considering how many of them there are- not even considering how many individuals of each species there are- there's definitely a lot of shipping potential there. Anyone else ship off the actual Pokémon?
In my games, I like to headcanon certain Pokémon having a relationship at times, regardless of actual egg group. In Pearl, I viewed my Lucario and Lopunny as together. Same with my Seismitoad and Lilligant in White, and my Lucario and Delphox in X.
I also really love Giratina x Shaymin. The contrast is just interesting in the two, and there is some neat fan art out there for them. They're also among my favorite Pokémon. Regigigas x Shaymin is cute too, with Regigigas as a gentle giant. Its shoulders even resemble Shaymin a bit.
Xerneas x Yveltal is another fun one for contrast. I'm a bit sad I haven't seen much fan art for it- it's probably among my favorites. Darkrai x Cresselia is another one that's grown on me in recent years, and the fan art for it is gorgeous.
My favorite overall at the moment though is probably Sky Shaymin x Land Shaymin. I am utterly shocked I did not get into this one sooner. It's right up there with my human OTPs for Pokémon. It's just pure cute, and both Shaymin are my absolute favorite Pokémon. The fan art for it is also pure adorable.
And that's not even touching Mystery Dungeon ships. Explorers of Time gave me Turtwig x Squirtle with the main characters for my game, and then Sky gave me Meowth x Vulpix. And, of course, there's Grovyle x Celebi and Loudred x Sunflora.
EDIT: I see the thread now, but it's locked, so I'm assuming this is fair game now?
