Linger Remnant

Lingering Remnant:
Description: It all began in a different universe from this one, a universe known as The kingdom of hearts. Where worlds were intertwined with each other between darkness and light. But in it all was one dark power that a being known as Vanitas was named after. The Linger Remnant, being the power to linger at will and remain a remnant of ones self this was Vanitas's true poteinal. With the armor of linger will of Vanitas and his remnant form he was embodied the most powerful being in his universe. But a powerful being of light came forth and challenged the mighty being of darkness and prevailed, for the light within this young hero was far too powerful for that of Vanitas and Vanitas was banished away forever and wiped clean of all his powers. Some say his remnants still exist somewhere in a universe and they slowly grow stronger and stronger as they gather the negative energy of the worlds.
Ability: Gives the person stronger endurance to physical blows (50% defense boost) as well as stronger endurance to magical blows (50% special defense boost) 
Usage: Usage is mainly in battles, where the defensive and special defensive stats raise by 1/2 of the original defense and special defense

While I don't really have a problem with the ability, you don't get to just make your own lineage.

And if it's not yours. . . .why even put your name in the bio?

My only issue is the format of the power. You say 50% increase in defense... which can translate to hundreds of things.

Are you just saying "Takes half damage from all attacks"? And if so, it's a bit over powered, and would need a max damage cap. Like "Takes 50% damage from all attacks under _ Rank." or whatever.

Could you actually scrap this? I've no interest in it anymore. It's nothing wrong, just I don't think i can go anywhere with it. Sorry for wasting your time.
