Robo knight was a headmaster too.

Should Alpha become a Ranger in the comics?

No thanks. Maybe make him a weapon like Arthur G6 from Fiveman instead.

Could Toei make a PR show without Saban if the rights reverts to them in 2019 ?

Why would they do that though? They have Super Sentai, not to mention they don't have to wait for Saban and then Hasbro to drop the rights

Could these be used as Ranger colors at some point, even if 2 of them aren't colors?

Brown, Rainbow, and Clear (invisible) but you can see some of the suit like the visor, collar, gloves, boots, and team logo.

ToQ Ichigou of the Rainbow IS a Rainbow Ranger. Never had a Brown Ranger before, but it'd be cool to have one. A 'Clear Ranger' would either look no different from a White or Silver Ranger...or you'd just see the guy underneath, so there'd be no point.

My idea for the Clear Ranger was like the Invisible Man, it would just let the visor, gloves, & boots can be seen.

So that Billy Gold Ranger statue got a Ranger Key and no one realized it.
