Cackles

Izuku - Calculating and pretty chill. He spends a lot of time with steeple fingers and petting Tae's hair while he plots against Kacchan and his other former-friends. Homie lowkey has a dark-web info rivalry with Opal going-

Opal - Not even 100% a villain. She fuckin' plays every side. Sometimes she plays with the villains, sometimes she helps out the heroes. She's certainly a loner. She's cut ties with her old friends and her mentor Kamui Woods and has buried her love for Shoto, though she occasionally indulges it via taking shots at Endeavor's head.

Saitae - THEY ARE B A T  S H I T  C R A Z Y. Tbh, they're kinda an attack dog for Izuku. They toy with people for shits and giggles before they actually off them or whatever. Lots of crazed giggles.

Katsuki - honestly, he cant be a villain. he cares too much about all might and heroism. So!! He's dedicated himself to taking down Izuku and Saitae just to spite them. Bc fuck Christmas colored hair >:(

Kero - He's a pretty passive villain. His whole gist is I break in, I stab people, I hide the evidence and burn the bodies, I leave. He's sad that eijiro's hunting him down now, but Y'know, "It's been fun playing with you, but I have better toys now."

Shoto - As a villain, he's cold. He's ruthless and efficient and holds back nothing. The only time he doesn't almost murder his opponent is when it's Thorn trying to drag his ass back to heroism because although he won't ever admit it, he misses her company. He plots and plans and doesn't move without a purpose. Also he's got killer taste in suits.

Omori - She, much like Tae, is batshit crazy. She says she's doing what she does for justice or karma, but tbh, she just wants to take down the League of Villains because they kidnapped Bakugo and Orihara a while back, and being a hero wasn't getting it done fast enough. She thinks her father would be disappointed in her, but she's too far gone to really care at this point.
