The protagonist doesn't have any goals, he is not that interesting or unique, he lacks memorable introduction, he is without distinct personality, special qualities or traits.
His desire is to explore the world or universe and engage in missions which is not that original or captivating. He is not intelligent either as he freely reveals information about himself and his strengths, without any semblance of strategic thinking or hidden agenda, and his abilities, which consist of being strong and immune to various things, are far from unique. While the writing may be good and the chapters are long, the story itself is boring, lacking any standout moments, elements to pique the reader's interest, or an engaging and gradual storyline, instead of thrusting the protagonist into an instant galactic race and mundane missions, it would have been more intriguing to see them explore a small, unfamiliar planet starting his journey to become stronger as a villain.
