Spencer
From Runsafe
"Spencer" was a villager incorporated into the 2023 Halloween Event as the main antagonist. After being slain multiple times over, "Spencer" vowed revenge against the admins & playerbase collectively, prompting the admins to delete his villager body. Despite this, several sightings of a Wither Skeleton claiming to be "Spencer" were reported in November (following the closure of the event), leading to concerns that his AI still exists somehow. Notably, this should be impossible or very unlikely, which could be indicative of a hoax.
