very well

fourth impossibility is all/any impossibilities except for three above

I selected this name because traditional parables called it three impossibilities

okay I can explain:

Ghoul type of shapeshifter jinn, phantom or monster who breaking on graves and eating corpses

Anqa legendary bird, who eating its victims while sunset

Loyal Friend, not really loyal person, he/she legendary figure who have all control over herself/himself enough to stay with you to lifelong if he/she want fictional example for loyal friend: Bentham from onepiece

user can't transform into them, but use their abilities better than them
