Deadsiders are one of the non-playable characters in LEGO Dimensions 2: The Rise of Enoch, from the Shadow Man franchise.
The Deadsiders are the primary inhabitants of Deadside and are rumored to live there in extremely large numbers, as Deadside is the place where everyone goes without exception when they die.
When found they usually dwell in the paths of shadow or near blood falls curled up.
Some of the Deadsiders were collected by the Hookmen and shipped through the Asylum Cageways in cages to be harvested. Since they are in the thousands, there will always be meat to be taken. They are then tortured and slaughtered by the Hookmen and shipped in meat boxes to the Surgeons in the Asylum Playrooms, where they will be re-patched together to create giant Frankenstein-like creatures called Trueforms to wreak havoc upon Liveside before destroying the earth.
