Todoroki is notorious for falling asleep during movies. Not only that, but he does it intentionally-- He barely sleeps, so if there happened to be a time where Deku and his friends invited him to see a movie or something, he'd gladly accept, sit down in that seat right next to Deku, settle himself in, and think 'Ok, time for a good rare hour of sleep...~' and before the commercials even finish his head is already falling on Deku's shoulder and he is OUT. HE DOES IT DURING HORROR MOVIES, TOO. Everyone else is screaming and being scared, while Todoroki is absolutely DEAD to the world and just sleeping his troubles away. It's almost scary. (He does it on school buses, too. Pretty much any place where he's sitting for long periods of time, besides class, he's out like a light. Only Deku is comfortable enough to sit next to him because of this, in all honesty--)
