An upgraded version of the already existing SCP-939.
SCP-939 size has been reduced by 25%, it's faster than humans and will get slowed down after hurting someone. In return, its attack will be boosted based on the damage taken. The adrenaline bar will show how much angry it is.
Credits to Reddking#2021 for the great idea.
EXILED 5.3.0+
