Guys! I have too many Halloween costume ideas and I need to know which best stuits me! Which do you guys think is the best for me to wear on the third day of my Periodical exams on October (not sure when)?

Here's what I have so far:

Komaeda Nagito from Super Dangan Ronpa 2

Freddy Fazbear from Five Nights at Freddy's

Lumine from Megaman X

Cyber-elf X from Megaman Zero

Copy X from Megaman Zero

Sage Harpuia from Megaman Zero

Aile from Megaman ZX

OVER-1 from Rockman Xover

Gao Mikado from Future Card Buddyfight

Megurine Luka of Vocaloid

Sky Does Minecraft

SimonHDS90

Einshine

BajanCanadian

SetoSorcerer

Nyansai

LDShadowlady

After picking someone, give your opinion why I should be him/her. The best opinion automatically becomes my costume.
