Twice (Jin Bubaigawara)

Twice's appearance
Twice has a very distinctive design that perfectly reflects their state of mind:
Full black bodysuit-style suit, quite tight.
White mask with black lines, which completely covers his face.
👉 This mask is key: it symbolizes their loss of identity.
Messy blond hair, visible when she is not wearing the mask.
Slim but athletic build, not overly muscular, but agile.
Medium-tall height, with a generally hunched or relaxed posture.
📌 Important detail:
When he takes off his mask, he looks more “human”… but also more vulnerable.

Twice's personality
This is where his character truly shines (and hurts).
🔀 Fragmented personality
Twice suffers from a serious psychological problem stemming from his own gift.
He constantly has contradictory dialogues with himself:
He says something… and in the same instant denies it.
For example: “Yes, let’s do it! — No, that’s a terrible idea!”
👉 This isn't just comedy, it's a symptom of his trauma.
💔 Fear of not being “the original”
His greatest fear is not being the real him.
After creating clones of himself that rebelled, he completely lost the security of his identity.
That's why:
Wear a mask.
Avoid showing too much of yourself.
🤝 Extremely loyal
Within the League of Villains, he is one of the most loyal.
Especially close to:
Himiko Toga
Tomura Shigaraki
👉 He doesn't see the League as "allies"... he sees them as family.
🧸 Surprisingly affectionate
Despite being a villain:
It is protective.
He genuinely cares about others.
He has almost tender mannerisms:
She gets anxious if someone close to her suffers.
He needs affection and belonging.
😂 Chaotic but functional
It may seem comical or ridiculous…
But in combat he is very dangerous and intelligent.
He knows how to use his gift strategically when he is focused.
⚠️ Its darkest side
His story is marked by:
Extreme loneliness
Social rejection
Mental breakdown
👉 It's not "bad just because."
He is someone broken who found acceptance in the wrong place.

Don (bonus to understand it better)
Double (Duplication)
You can create exact copies of people (including yourself).
The copies can operate independently.
Problem:
If they receive too much damage, they disintegrate.
This directly contributed to their trauma.
