A few headcanons under the cut that I have for Israphel and Minion (Skeleton minion) because I find the animations ridiculously funny.
He's convinced his plan is the center of all worry thus he stupidly believes Xephos and Honeydew still care to stop him.
The reason why he hasn't killed Daisy yet is that of wanting the heroes to reach them and watch him sacrifice her, thus...It's for the purpose of boasting and mocking them.
He spends hours sitting in front of a desk, writing down odd plans that sometimes make no sense at all and just end up messing up right away. He thinks they are brilliant and won't admit to their visible flaws.
He won't admit it, but Minion (The Skeleton minion) is his favorite which is why he's always calling him to join in on his plans instead of Zombie_Boss or Creeper_Boss. He's the closest Israphel has to an actual friend.
He used to be an incompetent salesman before he died, which is where he got his never ending patience from.
For a skeleton, he has terrible aim and breaks bows or arrows very easily, so he gave up on using any ranged weapons a few days after becoming an undead being.
Minion is the kindest out of all of Israphel's followers, even going as far as to take Daisy her meals and even talk to her. They both agree Israphel's plans are ridiculous.
While Israphel insults him often, Minion doesn't take it to heart, in fact he considers the dark Lord one of the few friends he has since no one really wants to befriend a skeleton.
Minion is very uneasy around other skeletons since they tend to mock him due to his archery skills being fairly poor.
