The Engel Norns (Angel Norns) are a genetic breed by Marcus K. that uses Chichi Norn and Winged Chichi Norn sprites. Compared to a normal norn, they have a stronger immune system, need less food, and don't get injured when hit. They can also eat detritus and gain nutrition from being petted. They become much more fertile when they speak.
