Unable To Become The Main Force

I’ll never understand what’s the point of making your character an underdog, if you are just going to throw all blessings under the heaven to him. The whole point of an underdog character is someone who struggles against advercity and bad luck. Such character become pointless if you just throw him an unique chance to become GOD that no one else has, or if you make him the bloodline fated second coming of christ king of the moon, like Naruto. ( Lee was the true protagonist change my mind )
