The Chaos Koffins (also called Chaosrealm Koffins) are strange floating coffins with a sophisticated and gothic design, created by the natives of the infamous Realm of Chaos. They made their debut appearance in Mortal Kombat: Deception.
These Chaosrealm Koffins are like any other coffin from other realms including Earthrealm, but are done with the Chaosrealm's unusual funerary procession. Each Chaosrealmer buried within those koffins, are lain to rest forever.
Shujinko, while exploring the strange Realm of Chaos, discovered the Chaos Koffins within the realm's cemetery.
