Buzz Lightyear Gets an Origin Story

Well, this is…weird. I don’t know what this is supposed to be, because Buzz Lightyear, the toy, was supposedly based on a superhero character that existed within the Toy Story universe, so is this a fictional movie within said TS universe, about that superhero space ranger guy? Or is it supposed to be like, a real guy that the toys/character was based on? Also, it’s gotta be a bit odd to some that Tim Allen, who’s kind of synonymous with Buzz Lightyear, isn’t the voice here all of a sudden (it’s Chris Evans now).
