Pretty much any episode where a female character loses could be considered this, given the entire purpose of the show is determining which fictional character would win in a fight.
An episode features Magneto fighting Tetsuo Shima from Akira, who is probably the poster boy for anime body horror. His depiction here is no exception.
Pretty frequently. Some examples include the endings of Wolverine vs Raiden, Silver Samurai vs Shredder, Sub-Zero vs Glacius, TJ Combo vs Balrog and Sabrewulf vs Jon Talbain. Also happens in Dracula vs Ganon, although it doesn't stick.
Several losing characters are parents. This includes, but is not limited to Vergil, Ken Masters, Geese Howard, Jotaro Kujo, Bowser, Goku, Vegeta, Cable, Johnny Cage and Bayonetta.
By default every episode features a character dying, of particulate note are the ones where a heroic character dies against a villainous one. However, it's worth singling out Jonathan vs Tanjiro, which features a depressing ending in any context.
