I've recently come up with the idea of a rival continuum for the Q Continuum. I had decided that since I decided to name so many of my characters in so many inter-connected stories with the initial L (originally started by Death Note obsession), I needed to come up with an explanation in order for this to make any kind of sense at all. And because I decided to make one of these characters a draconiquus with powers similar to Discord's but only uses them for good, I decided to create an arch-enemy for the Q Continuum, called the L Continuum.

Any thoughts on this idea at all?

Maybe use a synonym of continuum for the L...also try to not make them simply rip-offs of the Q...which must be pretty hard. Seriously, making original rivals for a omnipotent race must be super hard.

I would think just a very, very smart normal human would be a great enemy. Someone that can turn Q on their heads without actually being powerful.
