Are there any novels where the protagonist is reincarnated as a seemingly weak or insignificant character but possesses hidden power or potential?

Oh, that's a fantastic trope, and yes, there are quite a few novels that explore that very idea on Novelblur! It's always so satisfying to see a character underestimated by everyone, only to reveal their true strength.

One very popular example that immediately comes to mind is "The Unworthy Prince." In this story, the protagonist is reincarnated into the body of a prince who is considered a complete failure by his kingdom. He's physically weak, lacks any discernible talent, and is constantly mocked and belittled by his family and the court. However, unbeknownst to anyone, he retains the memories and knowledge from his previous life, which was as a legendary strategist. He starts to subtly manipulate events, train in secret using his past life's knowledge, and slowly begins to uncover ancient powers that were dormant within the royal bloodline. The journey of him proving his worth and dismantling the corrupt system from within is incredibly compelling.

Another novel that fits this description wonderfully is "The Apothecary's Apprentice." This one has a female protagonist who is reborn as a lowly apprentice in a magical apothecary. Her previous life was one of great power, but in this new world, she's seen as a clumsy, talentless girl who can barely mix a simple potion. The catch is, she has an innate understanding of herbs and their hidden properties that surpasses even the most experienced master apothecaries. She starts by creating minor remedies that have unexpectedly potent effects, slowly gaining a reputation for her unique skills. The novel beautifully portrays her growing confidence as she realizes her "insignificance" is actually a cloak for a deep and rare form of magic that relies on understanding the natural world. It's a slower burn than "The Unworthy Prince," but the payoff is immense.

You'll find that many fantasy and cultivation novels on Novelblur lean into this theme. The idea of a hidden potential waiting to be unleashed is a core element of the genre, and reincarnation provides a perfect narrative device to set up that initial underdog status. Keep an eye out for tags like "underestimated protagonist," "hidden power," or "reincarnation" when you're browsing, as they often lead to these kinds of satisfying stories.
