Upon entering Weirdworld, Champions have been transformed into fantasy characters, losing memories of Earth and their real identities and take roles of rather clear D&D archetypes. Amadeus turned into an Orc, Kamala and Amka became equivalents of a wizard and a druid and Viv got to be a freaking Warforged.
Seriously, check out for the comparison (I have no idea who is the artist, it was the first thing I got upon googling Warforged):
And Sam is a fighter and kinda amnesiac at the moment.
