I'm in the market for new nemesis at the moment (my old nemesis is no longer my nemesis). Who will it be? Feel free to add your own ideas or nominate people (who are either already on manifold or consent to be listed).

This market resolves to whichever option best describes my nemesis at the next moment at which I have one. If I have no new nemesis by the time school ends, then this market will either resolve to whichever option best describes that (if there is one) or N/A if none describe that at all.

NOTE: To refer to Yapa Glover, use YapaGlover, not @AtomGlover.
