Let's assume you know your mutants: Multiple Man, the MLF, Mystique, New Mutants, Nightcrawler, Northstar, Cassandra Nova, Omega Red, Onslaught, Phoenix -- no surprises for you there. Safe to assume you know Aunt May from Uncle Ben, but do you need a flow chart to tell Namor apart from Namora apart from Namorita? When it comes to heroes, how are you on the New Warriors, Night Raven, Night Thrasher, Nightmask, Nomad, Nova, Omega the Unknown, the Order, Paladin, Patriot, Penance, Phantom Rider or Pip the Troll? Villains, you say? How about Mysterio, Nebula, Nightmare, Nitro, Ord, Orka, Norman Osborn, the Owl or the Phalanx? Places like the Negative Zone and New Universe? Wrap it together with more than a hundred entries in all! Yes, you do need the Official Handbook of the Marvel Universe. You're welcome!
