Minecraft Hardcore Deaths

Despite the fact that Dan has yet to die in his Minecraft Hardcore series, many of his characters, pets, and enemies have died.

Prisoner
For Dan to get the "How Did We Get Here?" advancement, he needed to do a raid for Hero of the Village, he does this in his base, but because his illager prisoner automatically joined the raid (according to the official rules), he needed to be killed to finish the raid.

Skinny
During the same raid that killed his illager prisoner, Dan was attacked by vexes and Vex Himself from an evoker. He was knocked down from his castle by Vex and attempted to shoot Him, however, he missed and hit Skinny instead, killing Skinny.

Attacc, Protecc, Smacc
Attacc, Protecc, and Smacc are DanTDM's Iron Golems. They die through out his Hardcore Series, dropping Iron. Attacc died at the hands of a skeleton in Episode 11, and was the only Iron Golem that dropped a flower. Protecc died at the hand of hostile mobs, in Episode 11 as well. Smacc died in Episode 11 also, but it is uncertain how.

Number 1
In the last episode of Dan’s Minecraft Hardcore series, Dan attempted to get an advancement involving shooting 5 different mobs with one crossbow using Piercing. He chose a cow from his cow farm, which he nicknamed Number 1 because it was the first animal acquired. He then later shoots Number 1 for the advancement, but due to the having too much health, died without Dan getting the advancement.
