Well, I don't mean that exactly. All Kamen Rider series have the heroes and villains derive their powers from the same source, it's one of those intrinsic Kamen Rider things. In Ghost, for instance, the big thing is Eyecons, and the big theme is, well, eyes. In a general sense, everything in Ghost shares that eye motif.

So yeah, Necrom does have shared motifs with the other Riders: eyes, hoodies, etc. But the eye drops are more specific than that. None of the good guys so far have been shown to have anything to do with eye drops. In fact the only thing we have seen the eye drops used for is summoning Ganma, which is, you know, not a good thing. So when a Kamen Rider comes around with an eye dropper strapped to his wrist, well, you wonder.

True, again, I was just referencing the rumor regarding Necrom being evil, and you brought up an interesting point with his device and it's connection to the villains.

Just seen the first two episodes, looks promising! Onari just steals the show!

Just had a thought. Takeru comes back to life after he collects 15 eyecons. When he regains his life, will he continue to be Kaman Rider Ghost, or will he lose his powers?

He'll lose them probably, if he returns to life he isn’t a ghost anymore, and being a ghost seems to be the criteria of being able to use a Ghost Driver.

It’s kinda like past Riders who became more inhuman while using their powers, only that Takeru became "un-human" in the very first episode when he died. I mean we’ll probably see something similar later when he accustomed himself to being a Ghost and maybe he doesn’t want to come back anymore, but that’s going over your question.

I just think living humans can’t be a Kamen Rider Ghost.

But he was told that if he doesn't get the eyecons and regains his life that he'll be gone forever. I think that means he'll just vanish or finally pass over to the afterlife. And this might be a little heavy of a convo.

Damn WiFi acting up! Someone please delete this post!

Worth noting that Makoto is alive, and a Ghost Rider. Of course if the coma thing is true it complicates things, but that's still an alive human dude being a spooky Rider.

Considering that they're going to keep bringing him back for crossovers and stuff I imagine they'll leave some mechanism in place for him to keep his powers in any case.

Or, as usual, they'll just completely ignore whatever happened at the end of the Rider's series and bring them back with little to no explanation (example: Ryuki) lol.

Well, pre-Decade shows are different since they didn't really start doing or factoring in crossovers until then. I don't really know, since I've only seen Gaim and Drive, but I got the impression that W-Fourze also left the Riders with their powers or some way to access them at the end.
