I'm looking for sci-fi animated series/movie. I watched this video in VHS. Plot was interesting: galaxy empire (there were ugly monsters bigger than people as emperors). The most important thing is rose or other flower (artefact). Monsters attacked planet of people and war robots. Main army of empire was robots, as well. Men from our planet destroyed rocks above attacking robots. They walks on rocks and are glading from victory. Unfortunately, robots survived - one from their catched for leg one from people. Empire of monsters was very big, they have robot-wolves (or something similar). I remember other scene - humankind as prisoners are in barracks. Then was emperor from this empire and ask their about flower-artefact. Then, block of flats (with prisoners) are destroyed. Pessimistic atmosphere.
