Neon Queen is a new custom stand I think. I've personally seen it once.
E - A very strong barrage
R - Strong Punch
H - Return To Zero
G - Pose (plays retro clown man music)
T - A super strong punch dealing about 10k - 15k or 1 million at most. (Has insane knockback better than celeb pot or ocd)
C - Spammable roll
Z - Spammable jump
X - 100% block
The owner showcased it to me I think he/her is an admin of some sort.
