Ah yeah, I just realized that it would be Px, and well, Px is Phantom. I suppose it could be model Rx, for just Reploid or somesuch.

Ah, now that you said the model name, I can kinda see why they didn't do that.
They both start with P, and they would conflict with each other and Model P.
Unless they'd be named Model PA and Model PR.

That would have been kickin-rad, a model Px that combined them would have been cool

I like Prometheus because I love scythes as much as I love swords

I wish in Advent you got to copy them. That would have been ridiculously rad.

I love me some Megaman Zero, and ZX wasn't that bad either. Although I prefer Pandora to Prometheus vv
