Here we have Saraph the Blaze, Barren the Enderman, Ace the Skeleton, and Steel the Iron Golem.

Saraph is very promiscuous and a little full of himself. He always makes bad flame puns and acts like his existence is the only reason you continue living. Not the nicest guy to be around but he never wears a shirt so I guess you can manage.

Barren is Bi Polar, going from really shy to really violent at the drop of a hat. He hates attention and wants to fall into the shadows. He is also a bi of a Kleptomaniac and OCD, taking away anything that catches his eye and "Helping" the player by moving blocks to where he thinks they look better. It is very easy to scare him away making him the hardest mob to become friends with.

Ace is a very confident hunter. He is a bet vengeful, seen by his tendency to attack other skeletons or mobs that hurt him, even by accident, and he hates Atom the Creeper. He sees himself as a defender of nature and sees creepers and players as nothing but leeches he must destroy, despite that he can be swayed if he sees what you can do for nature. He claims that the lands belonged to him and his family before they died which is why he guards it so closely.

Steel is an artificial life form created by using a pumpkin to call a spirit into iron. He has no memories of his life before his spirit was bound and honestly doesn't care having a rather cold personality. He will refer to you as nothing but master at the start and would find it odd that your talking to him, but after a while his true personality comes out. He loves villagers, especially the little child villagers, he's a sucker for baby animals and likes flowers, the more human he feels the more defensive he starts getting to hide his personality and be the big tough guardian he's meant to be. He is afraid of Adam the Creeper, something Atom uses to his advantage.
