Intense backstory,Cleverly skilled in combat,has a magical power,cool name,original the way he doesn't have cutie mark.Well this is another brilliant character who will have an epic affect on the story also his personality is perfect for a role I had in mind.
Recap this is what I am thinking of so far (please feel free to reply if you would rather a change would occur)
A group of assassins will attempt assassinate Queen Chrysallis who has decided to become an evil leader of Equestria ,these assassins will have to rely on there stealth skills to sneak past countless numbers of changeling troops aswell as ponies who have been hypnotised.
This is just an extremely basic overview of the possible storyline please feel free to input your own ideas in the process.
