I am looking for the name of a cartoon that was anime-ish in both drawing and story-telling styles, though I am pretty sure it wasn't an anime. It aired:
- Somewhere between 2000 and 2010 (I believe it MAY have aired concomitantly to Ōban Star-Racers, so around 2006?).
- On Nickelodeon, Cartoon Network or Fox Kids (which became know as Jetix around 2004, at least where I lived).
- In Latin America (although I am pretty sure it was originally in English or French, possibly a Canadian production as these were common in this timeframe and location).
I happened to watch maybe 3 or 4 episodes of this cartoon. I remember hating it, but maybe it was mostly only these episodes? Here is what I remember of the plot, although I am not certain of any of these details:
A few years after an apocalyptic disaster that seemed to kill or mutate almost everyone and destroy pretty much everything (scenarios in the cartoon often showed destroyed buildings and cities), we follow a young woman with somewhere between 1 and 3 companions.
The woman was a non-mutated human, while her companions were mutants / androids, and the main (only?) one was lionesque in appearance: by that, I mean he maybe had a lion face in place of his own face, more or less like the Khajiiti, or maybe a lion face in his chest like the Manticore Megazord, or maybe just a mane-like hair with colors associated with lions, such as yellow and orange, like Lion-O; if there were indeed more than one companion, the lionesque one clearly played the role of a leader among them.
They seemed to have met her before the apocalypse, when she was the daughter of an important politician or maybe a scientist, but I don't think she remembered that (maybe she had been kept alive and well through the apocalypse in some kind of stasis?), and their (the companions') knowledge was only revealed through flashbacks: perhaps they were the woman's bodyguards, love interests, family or friends before the end of days? For some reason, they seemed convinced the main character would be safer not knowing of their ties with her.
The point I am most certain about was a battle against a snake-like humanoid: by that, I mean he was primarily green, maybe in one of his forms he had a snake head instead of a more anthropomorphic one, maybe in another form he had snake heads in lieu of hands, a little like King Hiss. That fight lasted for 2 or 3 episodes and was filled with flashbacks points where the enemy changed form and evolved (very anime-esque); despite the companions almost dying several times, they triumphed in the end (specifically, I think it was the lionesque companion who defeated the snake-like villain). This enemy seemed to also have some background with the woman, from before the apocalypse.
I know there are a lot of uncertainties in my description, but I tried my best to remember the plot. Hope it is enough!
P.S.: Despite a few similarities (such as the young woman, in a strange world, accompanied by three individuals, one lionesque, one perhaps an android) I do not think the show was based on The Wizard of Oz. The tone was far more serious and I can't remember parallels to the Scarecrow and Toto...
P.P.S.: Although I still can't remember an analogue to Toto, I have started to believe that the cartoon may have been an homage to The Wizard of Oz, but quite a veiled (and dark) one... Yet I have searched TV Tropes extensively as suggested by @jo1storm and couldn't find what I was looking for.
