A Facebook entry made me think of one of the cult animations of my childhood: Time Masters.
As a child, I was having nightmares because of it, it's not really a tale for little kids, more a sci-fi for young adults.
The French-Hungarian co-production was legendary to those days, 60 artists were working on it for almost 3 years.
Thanks to IMDb, there is a parents guide, what says 6 years and above for Germany, the age 13 for Argentina seems more appropriate.
Synopsis from IMdB:
Piel, a little boy, is left marooned on the planet Perdide after both his parents have been killed by giant hornet-like aliens. Thankfully an emergency transmitter provides him with instantaneous communication with Jaffar, an adventurer who was a friend of his father. This Jaffar convinces the current passengers on his ship, an exiled prince and princess, that a rescue mission must be undertaken. Its a long way to Perdide though, so Jaffar first picks up an old technician who knows that planet. Together with two telepathic aliens they start their mission to save Piel, all the time talking to the boy and trying to avoid him walking into danger. But on the way to Perdide, Jaffar and his friends encounter a lot of trouble themselves, including a hive of malignant angels and what seems to be a traitor in their midst
The featureless angels give me the creeps :-P
Back then I had a comic book made with the stills of the film, it's a rarity nowadays, I'll have to search for it in the attic at my parents house.
