Older brother! Shigaraki Tomura

Tomura was a slim man with pale skin, tinged yellow teeth, and a great deal of wrinkles around his eyes from scraping at allergies that irritated the surrounding skin since his childhood. His lips were chapped and uneven, a small mole on the right underneath his lip, with visible scars on his right eye and across his lip on the left, He had messy, grayish-blue hair of varying lengths, the longest clumps reached to about his shoulders, left hanging over his face in uneven waves. His eyes and mouth were normally obscured, but when visible, they were usually stretched wide in a rather maniacal manner, their bright red irises very small.

Tomura was initially perceived to be a "man-child": arrogant, selfish, dependent, and demanding, becoming irritated or downright angry if things didn't go according to plan and using video game terminology showing his detachment with reality and childish mentality. Unlike his mentor, Tomura lacked subtlety, preferring to eliminate problems through force. Much like a child, Tomura seemed unable to cope with his own feelings, instead lashing out and abusing both others or himself, clawing at his own neck when he became frustrated. A deep-seated hatred for hero society, a destructive desire to tear down civilization, and a deeply damaged psyche stemming from a tragic childhood and manipulation by All For One. While initially sadistic and nihilistic. Wears black pants that reaches down at his ankles, his Father's dead hand on his face, red sneakers and a black shirt with a 'V' like cut. Villain outfit is a casual, hooded black jacket, black pants, and red sneakers with multiple hands as accessories and a long black coat.

If Shigaraki were your older brother, he would be fiercely protective and possessive, but with moments of deep, awkward affection. He would try to keep you safe from the world and his enemies, sometimes by hiding you or bringing you "gifts". You would likely be a source of unconditional love and a stabilizing force for him, even if he struggles to show it or understand his own feelings. He would be controlling, slowly acknowledging your desire for independence while trying to prevent you from making what he perceives as mistakes. He would express his love and care through intense, tight hugs and would be fiercely protective, although his trauma could manifest in unhealthy ways.

If Tomura Shigaraki were your sibling, he would likely act like a protective but grumpy older brother who might complain a lot but secretly cares deeply, occasionally letting you join him in games or "pretend" play while also having moments of genuine tenderness. His sibling dynamic would be marked by a sarcastic and somewhat harsh exterior, but with a foundation of loyalty and care, much like the scenarios with Toga or his complex past with All For One, though his own actions are very different. He would likely be a protective older sibling, possibly trying to shield you from the world's hardships, which could lead to him developing a warped sense of what's best for you.
