Katsuki Bakugo

He has scarlet red narrow eyes and spiky cream colored hair.

very rude, aggressive, etc.

Ideal of Victory: For Katsuki, a "hero" is someone who always wins. Unlike Midoriya, who prioritizes saving, Bakugou prioritizes triumph over the enemy.
Fragile Pride: His aggression towards Deku at the beginning of the story is driven not by hatred, but by fear. Seeing the "quirkless" Izuku rush to his aid, Katsuki felt his status as "the best" was threatened. He perceived the help as an admission of his own weakness.
2. Intelligence and abilities
Despite his demeanor, Bakugo is one of the smartest students in Class 1-A.
Combat Genius: He doesn't just attack, he analyzes his opponent's weaknesses right in the heat of battle (remember his fight with Tokoyami or Uraraka).
Perfectionism: He strives for excellence in everything, whether it's studying, cooking, or playing the drums. His motto is to be first in absolutely everything.
3. Character Evolution (Redemption Arc)
This is a key part of his image. From a toxic bully, he transforms into a true leader:
Accepting Weakness: After losing to All Might and realizing his own guilt, Bakugou begins to change. He learns to recognize the talents of others.
Teamwork: While he previously worked alone, he later becomes an effective leader who utilizes the strengths of his comrades (for example, in the joint training of Classes A and B).
​Apology: The pinnacle of his development in the manga/anime is the moment when he sincerely apologizes to Midoriya, admitting his wrongdoing and past jealousy.
