Senshi Class

[Sailor Senshi Hunter]

As far as I know, there exists (fan-made):

Sol Senshi - The canon girls of the show.
Knights
Gemstone Senshi
Rainbow Senshi
Seasons Senshi
Zodiac (East and West) Senshi
Titan Senshi
Valkyrie/Storm Senshi
Ancients
Chibi Senshi
Constellation Senshi
(They are little fairy like) Senshi

So what class type am I missing? (Updated)  

[RS Sailor Brown]

Don't forget Zodiac Senshi, and well Rainbow Senshi are all fan made also  

[Sailor Senshi Hunter]

I did forget those two. Thank you for reminding me.
