when bakugo enter ua was he still mask emotion

Yes—when Bakugo entered U.A., he was still masking a lot of his emotions , but mostly through anger, arrogance, and aggression rather than obvious sadness. Early on, he comes off as cocky and explosive, and that reads like a shield more than full emotional openness.

What that looked like

• He used harsh words and intimidation to keep people at a distance.
• He rarely showed vulnerability directly.
• His confidence was real, but it also covered insecurity and pressure.

How to read his character

A lot of fans see Bakugo as someone who was emotionally blocked, not emotionless. He did feel things strongly; he just didn’t express them in a soft or healthy way. That’s why his early U.A. behavior feels so intense—he’s basically leaking emotion through temper instead of talking about it.

Simple take

So the short answer is: yes, he was still masking emotions at U.A., especially early on. The mask wasn’t “calm and distant”; it was “loud, angry, and defensive”.

TL;DR: Bakugo at U.A. wasn’t emotionless—he was emotionally guarded and covered it with attitude and aggression.
