I have extremely vivid memories of this 3D animated kids show that starts out as a boy who lost his parents and is now living on a garbage asteroid with a caretaker robot (his only family) who gives him warm milk. Then, in an absolutely gut wrenching (and I mean this unironically) twist, a planet destroying villain attacks, and ends up fatally damaging the robot, who’s last words are a slowed and distorted, “How about a glass of warm milk…” and the kid has a whole melt down. Somehow this triggers the plot where the kid (and some other people) end up going after the villain, and towards the end they also fix the robot and modify it for combat (it has like guns and is really funny) then they lock up the villain and if I remember correctly shuttle him into a black hole lol. Please, if this is real and you know what it is, let me know, it was my childhood.
