What is the random spike on Rotom's head?

Question

There's this random stabby spike on the top of it and it makes no sense to be part of a washing machine.

Edit: The rest of the Rotom have it too, so what is the spike?

Comments

It's just how game freak wanted to design in.. is it really that big of a deal to you to ask about it?

It's just a trivial question.  It doesn't have to be important to ask about.  Just curiosity.

Answer 1

It's not random; That spike carries from form to form : look at the sprites.

And now the forms:

Oddly, Mow doesn't have a spike, but all the rest as you can see do from the original form.

It does have a Spike tazzie You can clearly see it :P

it does have a spike but it's converted into a handle

---

Look at its head you can see aTriangle on the top of it :P

I didn't even notice that all of them had it. I wonder why Rotom in general have spikes.

Not a spike tho.... Spike =\= handle

Answer 2

I think it's supposed to represent a lightning rod.

"Rotom has a body of plasma and shaped like a lightning rod."

Hope I helped :)

Answer 3

All rotom forms have it. Rotoms forms all have a resemblence, the crazy eyes and smirk, and that spike, so its most likely why Rotom Wash has it, to look like a rotom!

Hope I helped!
