CycloneSkull as pretty much everyone guessed, it's only a hypothetical form.

W's one of the very few shows I've seen get this much merch mileage out of hypothetical forms

God, W truly does excel at “less is more” at least compared to their Phase 2 contemporaries. This form as well as Fang Joker having slight alterations that set it apart from the crowd, the vents on the mask invoking teeth, the tattered scarf, the mirrored body pattern, 👌🏾👌🏾👌🏾

what rider show is this it looks fucking rad

the original show was Kamen Rider W, this is from the anime sequel Fuuto PI, specifically the tie-in movie.

If futto pi gave shotaro the skull memory I would’ve flipped.

Just like Cyclone Accel and Cyclone Accel Extreme

Very Showa styled rider. I like it a lot

Now imagine SkullJoker

Aw so it doesn’t actually happen? Booooo

I wonder what an Eternal Skull would look like.
