What makes a compelling 'overpowered' protagonist in a fantasy or action webnovel, and what are some examples?

A truly compelling 'overpowered' protagonist goes beyond simply having immense power from the start. While raw strength is a common element, what makes them engaging is how that power is used, the challenges they still face despite it, and their character development. For instance, an OP protagonist might possess incredible abilities but struggle with social interactions, emotional maturity, or ethical dilemmas. Their journey might involve learning to control their power responsibly, understanding the consequences of their actions, or finding purpose beyond mere conquest. "Kaiju Maker in Another World" features Hayate Kurogami, who is catapulted into a world of monstrous power. While he's clearly destined for great things and possesses unique abilities related to kaiju, the narrative likely explores how he navigates this new reality, builds his influence, and potentially faces threats that even his overwhelming power can't easily overcome. Similarly, "Absolute Beast Dominion" presents a fallen hero who finds a second chance. The 'overpowered' aspect might manifest in his return with newfound strength or knowledge, but his journey will likely be about redemption and dealing with the aftermath of his past life's tragedy. The key is that even with immense power, there should be stakes, growth, and relatable internal struggles that prevent the character from becoming a static, uninteresting force.
