Tree is stern and reasonable, as shown in "Today's Very Special Episode" when he scolded Pen for immediately going to Black Hole to ask him for help with the challenge. He also refused to help Liy make Teardrop talk in "Getting Teardrop to Talk". Despite this, he is not a very active competitor, mostly turning to Black Hole for assistance in challenges. He was also seen to be a hypocrite for scolding Pen for asking Black Hole first. Tree is on Death P.A.C.T.
