The very first form that Chuck E Cheese took was the rat. According to the Chuckias, McCheese was a "god" like rat being that lived in a mythological place akin to Heaven known as the "Great Chuck E Cheese In The Sky". Chuck E Cheese would go onto do several things described in the Chuckias which is mostly mythological, however it did inspire the Chuckist Church to be built, and several schizophrenic leaders have claimed to hear Chuck E Cheese and became a "Head Priest" a title similar to a Pope. It must be noted that at this time John XXIII was not yet created, and the rat form merely exists as a mythological being that does not formally exist. It could be described as being similar to the Holy Ghost, although comparing the two in a serious or comparative way should NOT be advised. However after John XXIII was born, he for reasons only known to Dimond, was created as the bodily form of the rat. As a side effect of Dimonds experiment, Angelo Roncalli slowly gained great knowledge of the Chuckias, an unhealthy love for cheese, and slowly overtime began looking like a rat, until finally declaring himself the human form of Chuck E Cheese. The rat would then have a counterfeit form known as McWeed, who claimed to be the physcial representation of McCheese as a rat, however this condemed deemed a heresy by Pope Francis in his encyclical "Magisterialis Poopis Mystici Corporis Poopum Franciscum".
