This is probably very obvious but here we go
Dracovish is, as most people know, genderless. This means attract has no effect on it. This isn't very strange or new, as plenty of Pokemon are genderless. BUT, it is also in the Undiscovered egg group, the only egg group that cannot breed with others of its kind or the Ditto egg group. Again, not very strange. Most legendary and mythical pokemon are genderless, and all of them are in the Undiscovered egg group. The thing about Dracovish that makes me think this the shiny.
Not affected by attract, cannot breed, and its shiny is CLEARLY an asexual pride flag. This can only mean one thing...
Dracovish is Asexual!
I already liked it's typing (I love Dragon and Water types!) and loved it's design, so this just makes me love it even more!
