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

Characters: Ash Ketchum & Tyson
Canonical?: Fanon
Relationship status: Rivals
Also known as: SatoTet, TetSato

What do I think?:

I had no idea this ship existed and also Tyson looks quite a bit older than Ash (maybe like Brock's age?) so it would feel weird for me to ship them anyway

I shall rate this ship: -10/10

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