As in canon, Izuku!

Izuku kept running, before noticing that ice shot along the ground past him, before curving around to create a slippery patch ahead of him. Todoroki must have somehow managed to send ice ahead while using it to propel himself forward. Seriously, his skill with his ice Quirk was almost absurd!

Instead of stopping, Izuku immediately slid right at the ice like a baseball player sliding for the base, ensuring the upcoming slip was controlled, and in the direction he intended to go instead of stopping him. As intended, he skidded right over the ice, and the moment he cleared it, rolled with his momentum, and was running again the moment he was back on his feet.

"Damn it!" he heard Todoroki curse a bit behind him as his last ditch effort failed. He did not have time to try anything else, as Izuku crossed the finish line. As the crowd cheered, and Present Mic was announcing his win in the first event of the Festival.

"Damn it!" Bakugo snarled as he came in behind Todoroki, who looked annoyed, but otherwise took his loss with cool grace. Shortly behind them came Ochaco and Setsuna. Their team up, while unorthodox, had been incredibly effective, giving Setsuna fourth place, and Ochaco fifth.

"You bozo!" Setsuna smirked, bonking Izuku upside his head. "Were you trying to get yourself killed?"

"Meh, I'm tougher than I look," Izuku replied, rubbing his head where Setsuna had struck him as more students dashed in, Iida surprisingly coming in only at eighth.

"...to get eighth place in a race of all things..." he grumbled, looking quite depressed. Ochaco chuckled nervously as she tried to comfort him.

In nineteenth place came Momo... Who looked absolutely thunderous. "Momo? What's wrong?" Izuku asked. Instead of answering, she turned around, and Izuku froze, and then quickly saw red.

"Get. Him. Off!" Momo pleaded. And by him, she meant a battered and bruised Mineta, who was cackling, having used his Quirk to cling to her, and had taken obvious advantage to grope her. And clearly he hadn't cared about Momo's evident attempts to remove him herself.

"Two birds with one stone... I'm a genius!" he was grinning, too caught up in his supposed "genius" to notice the mortal peril he was currently in. He only noticed it when he felt a hand grip his head with very painful ****, making him shriek, and finally noticed the bloodlust in the air. His head was forcibly turned, and his soul left his body as he found himself staring into the face of ****, disguised as an extremely pissed off looking Izuku Midoriya.

"Get. Off. Her!" Izuku snarled, and Mineta, his self preservation instincts finally winning out over his perversion, obliged hastily. Before he even had a chance to start pleading, Izuku said, "Good. Now, Imma plant me a dumbass tree!" (Cookie for anyone who gets the reference!)

Mineta shrieked and flailed as Izuku slammed him face first into the dirt, though thankfully had enough restraint to not seriously hurt Mineta. Just give the flailing pervert a bigger nosebleed, and maybe a black eye. Technically, this was an illegal **** on a fellow competitor, but... Given the circumstances, every staff member of UA watching Izuku do this, and seeing the context, decided to spontaneously develop a temporary case of selective blindness. Very few people in the crowd would call bullshit on that.
