The Giant Rat lived in the Land of the Leprechauns.
He is likely a member of the ratkin race.
Behind the scenesEdit
In the original KQ1, the rat seems to 'magically merge' with the wall, in the remake the rat vanishes in a puff of magic.
In KQ1AGI, it is called 'the rat' or described as the 'big rat', the 'huge rat' or the 'greedy rat'. It is called the 'Giant Rat'/'giant rat' in KQ1 Hintbook. In KQ1SCI it is is the 'RAT'/Rat.
In KQ1SMS it is described as a large rat. It scuttles away.
