I have a huge list of ocs so I am just gonna go over my mains Blackwind: he would be a jerk who thinks it's funny when people get hurt but, he would also be highly carismatic and seem like a good guy.
Azreal: he would be uninterested in helping others and be highly keen on being happy all the time. He would walk all over others to gain that happiness. Hel: she would be very giving to everyone around her but secretly be waiting for a moment of weakness to pounce on them and rip them a new one. she would be generally evil but put on the face of a good guy. Mania Muse: she would be a normal pony who is highly charismatic and able to befriend anyone she comes in contact with. she would be uninterested in anything that is considered "creative" and would rather hate the concept seeing it as fickle and unneeded
Leviathan: he would he very very outgoing and charismatic. he would also be more then willing to work for free if it means helping out the wrong people. he would also love anything mechanical
