In the Yu-Gi-Oh TV series The Great Laviathon is said to have infinite ATK points and Obelisk the Tormentor is said to have infinite ATK points when he activates his ability to destroy all opponents monsters when the controller sacrifices 2 of his/her monsters. In the Yu-Gi-Oh trading card game there are no monsters with infinite ATK points and expectantly there will never be one because it will end up being classed as 'forbidden' or even 'illegal'.

Answer taken from the Official English Rulebook: After you've announced your attacking monster and the attack target monster during a Battle Step, the attack target might be removed from the field, or a new monster may be played onto the opponent's side of the field before the Damage Step, due to a card's effect. This causes a "Replay." When this occurs, you can choose to attack with the same monster again, or choose to attack with a different monster, or choose not to attack at all. Note that if you attack with a different monster, the first monster is still considered to have declared an attack, and it cannot attack again this turn.

The creator of lights atk. and def. are infinite.
Monster cards do not have life points and there is no concept of 'damaging' a monster card except for battle. In battle a monster either dies or it does not, there is no accumulating damage such as in Magic the Gathering. A monster can fight off an infinite amount of monsters that are weaker than it, but is destroyed if it battles with one of equal or greater power.
