@DRK _UNKNOWN There are some well written reasons why an MC hides his/her power, just not this one. This is pure bul*sh*t.
I.E. the kingdom/empire will draft all power users of certain type, x power user will be detained and used as slave due to rarity or fear, power cannot be controlled (cannot scale to a smaller degree) so he is deemed as an "evil godlike being", until MC gets supreme power level he is in danger of family killing him off (biding his time), and several others, not listing every single one lol.
