Garson is the name of the turtle shopkeeper at the waterfall, however he has proven to know a lot more about the undertale universe possibly to the extent of gaster or flowey.

In genocide Garson is the only shopkeeper who knows what you did and isn't afraid of you. If you threaten him, he says that "you can't hurt me here" and "it's that kind of knowlege thats kept me alive" this shows that he knows the player can't touch him in a shop as all the player can do is "act", he breaks the 4th wall here real good.

In a normal run he states that in the past, "Undine used to follow me and watch me beat up the bad guys", he is probaly a former hero but he denys it in genocide, (probaly to get the player off his tail.) Who knows what else he could be hiding behind that old grin, thats why if you guys have any ideas of what he could be please tell me.
