Okay I have watched the series ONCE and I still barely know half the names? And am too lazy to look them up? so, have a very uninformative list:

Stoneface - LWJ, who I call Potato (I'm sorry,I feel guilty about it, don't @ me, I know he suffers (like a potato in pain))

Jin Douche - the fancy arrogant guy Soup Girl is in love with and wants to marry? Whatever his name is?

Canary Guy - Nie Huaisang? Who is our Secret Mastermind pretending to be a failboat, and I love him

Sulkmeister - WWX's stepbrother who never met a sulk he didn't like

Pretty Evil Guy - the guy who just hangs around blinding and torturing people for no reason except LOLs

Jin Douche 2: ummm

Slimeface: ummm not my darling Meng Yao, I hope, he is no slimeface, he is an innocent little snacc

Cute Baby Cultivator: WWX and LWJ's son the turnip

Jim, the golden guy: not a clue

Soup Girl: WWX's stepsister the rib soup queen

How did I do? XD
