Izuku is caring and emotional, never hesitating to help or rescue someone in danger, even if he knows that he might not be strong or otherwise qualified enough to do it. He’s also extremely shy, socially awkward. Desperate to be a hero. Pretty weak. Adores All-Might. 

Episode one. A near-death experience.

(Just look up Katsuki Bakugo’s personality.)

You’re the thing he hates most

Katsuki is a crude, arrogant, short-tempered, and aggressive person, especially at the beginning of the series. Katsuki tends to come off as unheroic; this problematic behavior going all the way back to his early childhood days when he was known to bully. He was always pretty intelligent and also extremely prideful, stubborn and will never hesitate to start a fight.
