An anomalous slime like entity that wishes to share its existence with their host. They appear only when someone downloads the Mal0 app into their phones from any platform. Then these entities will send various messages to announce their presence in places you've been, eventually leading up to where you are. Mal0 will then try to affectionately merge with you via making you wear their skull mask in order for them to be whole, and for you to serve as their host.
