Brotherless

Item #:SCP 3000
-brotherless
Object class: safe/Eucilid

Description:
SCP 3000 appears as a boy around the age of 14-15, with dark blonde hair and sapphire blue eyes. He will enter the house of the said victim, as a foster child.
He will follow the mother or father (depending on number of male or female children), almost as if fleeing from something; trying to find shelter by their knew master, who then will be known as SCP 3000-A1.
If SCP 3000-A1 expires, SCP 3000 will turn to either the youngest or eldest child and seek compassion from them. That child will then be referred to as SCP 3000-A1-2. SCP 3000 will exhibit similar shelter seeking behavior as with SCP 3000-A1. If SCP 3000-A1-2, regardless of gender, tells SCP 3000 that it is like a brother to them, it's eyes will turn pitch black except for the sapphire blue iris' which proceed to glow and black ooze seeps out of nostrils and mouth, he will then proceeded to kill SCP 3000-A1-2 buy means of blunt force (bare hands) or a weapon favored by SCP 3000, a kitchen knife. When analyzed the substance had corrosive properties similar to sulfuric acid and had viscosity like melted chocolate.
Reports of this SCP were first noticed by SCP agent [DATA EXPONGED], who perused SCP 3000. He was never found, but a recording of a conversation between the agent and what can be assumed to be SCP 3000 was recovered.
