G.L. is a construct from Gremmy's Imagination. His powers are the three levels of Vanishing. He can make his appearence, form or Memory's vanish.
When he makes Memory's Vanish, anyone who has interacted with him forgets about him.
Gremmy's weakness is that He needs to concentrate on each thing he is imagining.
Therefore, if he suddenly forgot about an ugly old man he was imagining, the old man would cease to exist entirely.
Gueanal Lee is an Ugly Old Man who makes people forget about him.
G.L. Can act independantly of Gremmy, Because right before Gremmy killed him, G.L. attacked Gremmy. Therefore, Gremmy does not control G.L. and would forget about him the instant he used Memory Vanishing.
So memory vanishing would instantly destroy Gueanal Lee.
