Made even better by the death quotes the characters have: Ones that are normally heartbreaking become absolutely ridiculous when one considers that the speaker was killed by a wall. Garcia, for instance, says that it was always his fate, and Dozla claims he couldn't have asked for a better ending.
Or better yet, an enemy with a devil axe starting their Critical Hit animation then backfiring what would otherwise be a One-Hit Kill, shown here and here and here.
Or here, where the Devil Axe would One-Hit Kill but backfires without a crit.
The January 18, 2017 Fire Emblem Direct has some funny moments during the Fire Emblem Heroes segment, mostly revolving around the narrator and Lon'qu.
The narrator is hoping for Lon'qu to be summoned, only to be disappointed when Olivia is summoned instead.
Ah, the timid dancer Olivia. Can't rely on dancing all the time.
When Lon'qu is about to battle.
Fear not, Lon'qu is an expert swordsman— [Lon'qu only deals 4 damage against an enemy with 27 HP; the music promptly dies] Uh, oh.[the enemy completely curb-stomps Lon'qu] Gods, such tragedy. I'm afraid our fledgling Lon'qu has... a great deal to learn.
Even worse, Lon'qu lost even though his weapon had an advantage against his opponent.
