Sure, I'll try my best to improve the wording of the text while maintaining the general idea and tone.
Revised:
Marcus stood confidently in front of the burly man who resembled a bear. A smirk played on his lips as he flexed his muscular arm, now fused with a glove he acquired. The crowd cheered and jeered, eagerly anticipating an epic battle.
With a roar, the bear-like man charged at Marcus, swinging his massive arms. But thanks to his Hermes-like boots, Marcus was too quick for him. He darted left and right, easily dodging the bear's attacks.
"You can't touch me!" Marcus taunted, sticking his tongue out. "I'm too fast for you, bear-man!"
The bear roared in frustration and lunged at Marcus again. This time, Marcus decided to use the mysterious pill he obtained, granting him a newfound power. He quickly popped it into his mouth, feeling an unusual energy surge through his body.
Suddenly, time slowed down around him. With a grin on his face, Marcus watched as the bear's fists moved in slow motion. He easily sidestepped them and even had time to take a sip of his drink before the punches landed harmlessly behind him.
The crowd cheered wildly for Marcus as he danced around the bewildered bear. But just as he was about to deliver the finishing blow, his time-stop power wore off, and time sped up again.
Caught off guard by the sudden shift in time, the bear stumbled and fell flat on his face. Marcus, too busy gloating to notice his sudden advantage, tripped over the bear's outstretched leg and landed face-first into the dirt.
The crowd erupted in laughter as Marcus picked himself up, covered in dirt and embarrassment. The bear, now on his feet, smirked and flexed his muscles.
"Round two?" he growled, and the crowd cheered again, eager for more entertainment. Marcus sighed and raised his fists, ready to face the bear once more.
As the bear charged at Marcus, even stepping on a spectator's face to keep its balance, Marcus realized he was still new to his super strength and speed. Although he had gained amazing abilities, he was only a C rank, a second-rate fighter.
Marcus was on the losing end of the fight. That mysterious pill seemed to have the opposite effect on him, leaving him feeling tired instead of empowered. Not to mention, everyone there was C rank or above, and the strongest students were S rank. Marcus was currently fighting a B rank fighter. The only reason Marcus had yet to lose was his cheat-like time-stop powers.
"Thank you, Krono," Marcus thought, although his real name was Cronus. The gods had given him a nickname out of kindness and respect for his power. So, a human calling him Krono would actually be more irritating than it is a sign of respect. After all, they had just given Marcus powers, but this isn't Krono's tale.
As the bear charged at him again, Marcus sidestepped him and got into a boxing position, hitting him with the one-two-three jab combo. This repeated a few more times until a man dressed in all black walked into the entrance. He had flowing black hair and dazzling blue eyes, and Marcus immediately felt threatened as all the girls looked his way, twirling their hair.
"Damn it, first this ugly bear, and now a show-off who steals all the attention. When will the girls look at me like that?" Marcus took out a notebook and started taking notes in the middle of the fight, much to the bear's frustration.
As the result of the fight was obvious and Marcus was losing, one of the students said, "No surprise," and another said, "Marcus ran after him
After seeing the dazzling man again, Marcus couldn't help but take note of his striking appearance and remarked, "Hey, how do you maintain such a captivating look no homo?" The man ignored him and dismissed him as a nuisance. Undeterred, Marcus activated his time-stop ability and quickly retreated, feeling the need to strengthen his powers. He watched from a safe distance as the spot where he had stood began to crack, causing him to realize the gravity of his powers. Before leaving, Marcus left the man a parting gift: a swift kick to his crotch, causing the man to limp away in pain.
I apologize for the brevity of this chapter, as I am currently occupied with my latest project entitled "The Godfather of Evil: The Legacy of the Most Vicious Mafia Boss Amon"
