CoDzilla

CoDzilla is a 3e Dungeons & Dragons term, a portmanteau of "Cleric or Druid" and "Godzilla", describing a very powerful Cleric or Druid build. It came about because these classes have the potential to become game-breakingly overpowered when built properly. So great is the problem that playing a straight cleric or druid is often referred to as playing D&D on easy mode.

In addition to wielding considerable magical power that rivals that of the other reality-twisting classes - Wizards and Sorcerers - the CoDzilla also receives better combat skills and abilities, such as the ability to wear heavy armor for Clerics, better base attack bonus progression and, in the case of Druids, the combination of the wild shape class feature and the Natural Spell feat (which allows the druid to cast spells even while shapeshifted, when they already have considerable ability score buffs). By proper application of their powers, the CoDzilla is able to dish out massive melee damage and take punishment to a degree that equals or surpasses regular fighter-types while still retaining additional advantages such as magic, throwing the game out of balance.

4e has largely fixed such issues by leveling the playing field for all classes, primarily by greatly reducing the abilities of spellcasters to put them in line with nonspellcasters. Minmaxing touhoufags have nevertheless proven that 4e still has its share of broken builds, but they are generally not nearly as all-encompassingly powerful as the CoDzilla.
