Wandering-Oddity A8, A9, and B1
A3. What it takes to make them cry - they don't cry easily, but hospitals are a big fear of theirs. just visiting one can have them sobbing. hell if you happen to be a fucked up mind reader just reminding them parts of their past is enough to make them cry a river
A6. Things they don't like talking about - he doesn't like being asked about if they had any other kids before MC, as the daughter he had before them (child death tw) died in a terrible accident (i'm still trying to figure out what said accident should be) when she was only 12, to which mark takes the blame for
A9. Best way to push their buttons/make them angry - if you mess with his work on purpose, make sure to bring any medkits with you because oh boy. honestly if someone's just obnoxious in general he'd find a way to get away from them fast
B7. Habits - ngl he looks like the type of guy to click their pen over and over because of the sound
B12. Inspirations or general thoughts behind their creation - when me and my friends were still actively working on this mega man fangame we thought of 3 years ago, we figured that MC should have a scientist to go with them. and thus dr. enigma was born!
B13. Your favourite thing(s) about them as a character - despite their father being literally absent for their entire life, mark himself is a dedicated father figure who will protect MC and children in general with his life. him being a robot inventor and enjoyer is also what i adore about him
