Let's go through some basic knowledge before I talk about it further...

Characters: Pikachu & Piplup
Canonical?: Canon in Sticking with who you know! (DP149), Fanon in the rest of the series
Relationship status: Friends/In Love during DP149
Also known as: PikaPoch, PikaPip

What do I think?:

This is really cute and the closest we have ever gotten to a canon LGBTQIA+ couple in the Pokémon anime, and that weren't repulsed by the fact that they were both the same gender or found out they are the same gender and stopped liking each other
Brock was real homophobic though, saying they can't be together for "all sorts of reasons" >:(

I shall rate this ship: 4/10

Thanks for reading, see you in the next chapter!!!
