What if Chris had a Death Note? who would he take out first?
Imagine Chris Chans reaction to a shinigami, imagine being the shinigami that has to follow Chris around.
Anyways to answer your question: he'd likely take out Donald Trump, Mary Lee Walsh and Michael Snyder. Chris Chan seems to be somewhat lazy and likely execute people who've personally wronged him. He wouldn't be a danger to the whole of human society because of how simple minded he is, the real concern is what if a troll were to attain the death note? What if Bella got it? What is the government finds Bella and they have the death note?
What if Chris' AGP delusions had become real?
If Chris Chan became the attractive girl he'd always dream of being it would likely result in him becoming the biggest whore
What if Bella got caught early and Fiona and Chris got hitched,causing the birth of Crystal?
An infinitely darker saga than the one we have currently. Let's say they gave birth to a female Child, Best case scenerio Fiona would likely be doing all the work in taking care of it. Crystal Chandler would likely grow up being the most strange smelly child ever. I can only hope Fiona would put effort into making Crystal a decent person.
Let's say it was a male baby, Chris would likely name him Sonichu and automatically dislike him for being a dirty dang male, he'd likely try to get him to transition.
Anyways any offspring of Chris Chan would likely grow up in a hectic unpleasant life, you have to realize that Chris Chan doesn't give a shit about his pets and yells at them in the most menacing voice. He's likely do that to his Children. They'd likely end up hating Chris and might even "become" trolls.
