off the top of my head
howzabout:
autobot/decepticon (red/purple pills with the insignia pressed onto them)
hordakk (a pill that makes you feel like the badass that hordakk was. anyone else remember him from He-Man?)
einstein (e=mc2, a really spacey, intense pill)
stormtrooper (pure white pill, with helmet press, or mebbe empire insignia)
groo (anybody else think groo was probably rolling his way through his misadventures?)
suckerpunch/1inchpunch/bruceLee (a pill that knocks you on your ass)
I could come up with a 1000 more...
>sigh< so many names so little time...
