Uh... I'm sure I've already addressed this in my one shot book one too many times but here goes nothing.

Theory: Drew is a grass type Pokémon/Roserade

Now, before we get to the theory, I'm just going to do a bit of introductions for this relatively unknown Pokémon character.

Drew is a Pokémon coordinator, appearing in the anime version of ruby and sapphire. (I think?) basically, he's from the Hoenn region and is a rival of May, Ash's traveling companion.

And the thing about this is that he always wears a jacket wherever he goes...

In fact, I think there was only one episode where he took it off and ironically, it was for suntanning.

So, you get where I'm coming from.

Someone who has green hair (yes, he has green hair!) wears a jacket wherever he goes (probably afraid of the cold) and only takes it off for suntanning (aka photosynthesis)

Ok, I think I'm going overboard with the theory but I seriously think he's a grass type Pokémon.

On another completely different note, green hair is actually common in the Pokémon universe!

If you're wondering why I know this, it's because of a book project I've been doing.

I counted at least 5... and going on the Internet gave me a lot more. In fact, I originally wanted to add in OCs to fill the gaps but I guess I don't need to in the end.

In fact, I'm sure I've still missed out a ton of people.

Cheryl, Cilan, N, Aaron, Trinnia, Sawyer, Hau, Bryony, Mallow, Sorrel, Wally, Butch, and of course, Drew.

That's actually a sizable number of people. (There are 13 in the list)

I didn't even know there were so many...
