X1 Mask, The Forgotten Super Sentai Hero
 

X1 Mask from Hikari Sentai Maskman was actually the first Super Sentai sixth warrior in history. But because he was only a one-off character, he's been mostly forgotten by Toei.

Here's a video dedicated to the forgotten Super Sentai hero.

I'm glad someone else remembers him. RIP X1 Mask 1987-1988

I've got Maskman lined up to watch, so I'm quite looking forward to seeing more about him.

IMO they should have used this in Gokaiger. It would have made a nice bit for gai.

It would've been cool to see, that's for sure.
Seems like the kind of thing they'd bring up in Gokaiger...

The poor guy never even got a Ranger Key. :(

Eh, it probably wouldn't be hard to customize one from the Battle Japan and Red Mask keys. Just pop the Red Mask key onto the Battle Japan body, paint it green and black, and boom! X1 Mask Ranger Key.
