Tear Jerker: Super Dimension Fortress Macross
Misa's discovery about her first love and Victorious Childhood Friend Riber's death and Roy Fokker's death, specially in regards to Claudia's and Hikaru's reactions are still punches to the gut, more than 20 years after.
When Hikaru and Misa return to the Macross in The Movie, Claudia asks them about Roy, and if he died fighting. They answer yes, and she looks at them with both sadness and a little bit of relief (knowing his death wasn't senseless) and merely says "Thank you." Cue waterworks.
