Yes, and yes.
Look, plenty of people pick up games, or pick characters for stupid, superficial reasons.
Take, for instance, my interest in fighters.
Nowadays, I'm a moderate gamer with aspirations of one day competing at EVO.
Wanna know what got me into fighters?
The fact that
Zafina looked a lot like
Cristina Scabbia (lead singer of Lacuna Coil, one of my favorite bands).
Seriously, there are people who main certain characters, or get into the genre as a whole for dumb reasons.
Maining Freddy, quite honestly, is not that ridiculous. He looks like he could genuinely be solid, and you know what, a lot of people will main him SOLELY to troll the "hardcore" MK players who are butthurt over his inclusion, or people who are just genuine fans of horror and see this as a great opportunity to sate their fanboy/girlism.
