leaving out the whole space aspect? did you not see episode 7? if the show continues it’s only a matter of time before it branches out.
Ok I over-stated it, it is more in the upcoming episodes they had already made/written, as they have kept it on the planet now and are focussing on expanding the lore there, featuring characters (I mean how many have they planned just for pumyra right), their backgrounds. If the show does continue for more seasons, anything goes ofcourse, mandora might appear, etc.
Leaving out? It’s very intrigal to the main plot. Just think about Legacy. Probably and hopefully we will get more of those episodes to see what’s been happening in space and when they crashed.
Kinda sucks only Lion-O knows about it (regarding the gang). Would love to her their reactions, what if Lion-o would brought up Tygus in native son? Just to shed some more light on “what the tigers have done”. Not to blame Tygra though, just to tell him what the book showed him.
I think Lion-O has told them, just off camera. I mean if he didn’t they would’ve thought he was crazy for suddenly wanting to look for a bunch of stones.
You wrote this some where it is a kids show.
Do you spend a lot of time thinking about that? 
lol! 
I prefer the Leather Goddesses of Phobos, myself. 
Hachiman (possibly voiced by Peter Newman?)
the Lunataks
Safari Joe
the Demolisher
Oh, let’s not get me started(further) on Wonder Woman! Heh!
Haha!
The Lunatacs, oh yes, I would love to see them put in this series. I’ve already noted that their world has a couple of moons and seen some crescent moon symbolism in Mumm-Ra’s pyramid. I don’t know how they would work them in yet, but we don’t know all the ins outs of their world yet, either, so anything is possible.
Mandora and Mumm-Rana I could do without in this series.
The Warrior Maidens are characters I’d like to see in some way, even if they aren’t exactly human. (Like someone else said, a humanoid species like Duelist would work for me.)
As for how they reproduced in the OS, in my head canon I decided that they periodically hooked up with the Berserkers, kept the female children for their own ranks, and sent the males off with the pirates.
I can definitely see the Lunatacs in the NS. I wonder how they would look.
I cant see the Lunatacs being introduced very soon. However I would like to see them after they flesh out the current characters a bit more. The new design could be very interesting.
I can see them in a three or five part episode.
