Recommendations Underestimated or Hidding ‘Something’ Protagonist

Just as it said from the title.
I'm looking for a protagonist who many characters underestimated them, or a protagonist who hides something from the readers or the characters.
Recently, I've seen too many show-offs protagonists that I can't help making this forum.

I'm fine with any kind of genre as long it reached the requirement of being ‘underestimated’ that happens very often or ‘hidden something’ from the protagonist themselves.
So feel free to recommend without worrying about the genre or themes. Just remember that I asked for a particular protagonist. I'm fine with gore too.

 

My senior Brother is too Steady - The MC wants to be underestimated to the extent that even the readers are unable to determine his actual power. The only time you will see his full strength is near the end of the Novel. Prior to that you can see short bursts of his full strength, But you can never be sure if that is really his full strength or he was deliberately leading you to believe that it is. The story is amazing, Romance is Beautiful, And the story is finished. You should definitely give it a ready

 

Where are you finding these novels, nearly every novel I've read is the MC being underestimated lol.

 

XD... Yeah, that's so true....

Realms In The Firmament
Reverend Insanity
I Never Run Out of Mana

 

Nightfall
The Path Toward Heaven
Ze Tian Ji
Warlock of the Magus World
Age of Adepts

Idk man, these last three months I haven't read any MCs being underestimated.
From wattpad-webnovel-royalroad-gravitytales to novelupdates.
Recently, I'm reading this one protagonist who keeps wasting money left and right without remorse, and one who is self-proclaimed righteous kills other characters because of crimes even if they have a justified reason.
