Cabal Hybrids.
Cabal tries to control the Icon of sin and their demons, but seems so powerful... The only solution they found was using the old portal tech of the UAC and create the hybrids with a controlled space/time collapse.
The hybrids are monsters created by Cabal as result of the merging Cabal troops (cultist, zombies, gargoyles etc...) between demons of Hell (hellknight, revenants, imps, etc...), here you can see a video explaining it.
Hybrids are optional, you can be disable it through Bloom's options.
You can fight against hybrids in any official wads (iwad) even in your custom vanilla maps
