CoDzilla is a largely mythical beast. It is known to roam the Internet and the Character Optimization boards.
On occasion, a particularly careless DM may enable one to exist at a table, but this is rare. When it does happen, the beast is usually chained or else quickly destroys the game; only in exceptionally rare cases does CoDzilla enjoy the prolonged domination that is talked about.
More than any other creature, CoDzilla fears Dispel Magic. There is talk of a Reciprocal Gyre, an innovation devised specifically to kill CoDzilla.
CoDzilla feeds on splatbooks, nightsticks, and indulgent DMs.
CoDzilla is very slow-moving, taking considerable time to reach full strength and running out of energy quickly. CoDzilla can be thwarted by foes temporarily withdrawing or taking cover behind a tower shield for one minute.
