Tear Jerker / Buzz Lightyear of Star Command: The Adventure Begins

• The movie gets very dark just ten minutes in with the supposed death of Buzz's partner, Warp Darkmatter.
  Buzz: (solemnly) Space Ranger Warp Darkmatter sacrificed himself for the success of his mission, for the safety of his fellows. I miss him very much.
  • His log entry after the eulogy is pretty depressing too, where he blames himself for what happened.
    Buzz: Buzz Lightyear, personal log. In his crazed attempt to destroy me, Zurg has robbed the universe of a good man. My partner, my friend. On this day I vow, no ranger will ever again fall in harm's way because of me. I. Work. Alone.
• When Buzz first learns just who Agent Z really is, especially considering Warp was thought dead. It really doesn't help either when it turns out he and Zurg recorded a video of Warp's eulogy, and keep rewinding it at "I miss him very much" and laughing cruelly at it.

  Zurg: "He was not only a great ranger, but a great friend." (Evilly laughs) Oh, what a hoot! If only you knew! (Plays footage of Buzz saying "I miss him very much.") One more time! (Plays footage again and laughs) Miss him now?!

• The moment when XR gets graphically blown to bits by Agent Z in the movie, despite him being a non-sentient robot at the time. Buzz and Commander Nebula — who, only minutes prior, made it abundantly clear how much he hated robots — looked pretty devastated.

  Buzz: Buzz Lightyear to Star Command, this is a priority one mission update. The Uni-Mind has been captured, and... (cuts to XR's exploded remains) We've got a Ranger down.
