Dhelmise

[The darn 4th chaos emerald]

Is the scariest and creepiest pokemon in my opinion. In fact, it's the only pokemon I find creepy or scary, and its all psychological. The blue moss is what gets me really, It brings me back to my childhood when I played a lot of Mario Sunshine and that that particular shade of blue is a prominent color in that game and I had nightmares a lot of being locked in rooms of that color and being in scary situations where that color was also prominent. I stayed up late at nights playing Mario Sunshine and had nightmares like that. So yeah. GG Pokémon, you created my nightmare in pokemon form

I used to have a similar thing where I thought Cradily was creepy and had a nightmare involving it at one point, although I'm not sure why I was creeped out by it.

Dhelmise in itself is not particularly scary to me, but it does evoke shipwrecks, which are frightening imo. I'm not very comfortable with big sunken objects in general, be it ships or other structures.

If it makes you feel better, it's name comes from demise+helm. The seaweed is actually its body. Little is known about this fellow, other than it's absolutely awesome competitively, but I bet it enjoys your company.

I can't really agree with this; sure, to you it's scary because of a childhood experience, but I actually like the way that Dhelmise looks

apparently this pokemon is just the seaweed. It gained a life of its own and possessed the anchor. Rumor has it that a bunch of it took control of an entire sunken ship and the anchor broke off of it.
