@era-era: I should probably reclassify the lazy genius as arrogant genius
They all have their own problems to deal with.
kind idiotic berserker - is too afraid to hurt people to fight all out
lazy(arrogant) genius - won't do anything unless she gets her way, or you fool her into it.
introverted mad-engineer - she really just does thing on a whim, at best you can annoy her to accept requests.
dependable screw-up - almost never succeeds, but does so when it counts ;and is eager to prove it, over and over again if possible.(opposite of the lazy(arrogant) genius)
