Tree (TPOT/BFB)

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 and asking Black Hole for his help whenever Tree is in a dilemma. He was also seen to be a hypocrite for scolding Pen for asking Black Hole first.

This doesn't mean that Tree is 100% a "no-nonsense" type of guy, as he can be shown enjoying himself when he comes up with a scheming idea to steal blocks from the other teams in "The Worst Day of Black Hole's Life", having fun of the trampoline in "Getting Puffball To Think About Rollercoasters", and communicating through Yoyle Dance with Fanny and Marker underwater in "Fishes and Dishes", expressing a playful and carefree side to him.

Tree also has an interest in nature, as he is shown in "Gardening Zero" thanking Two for creating a challenge to protect plant life and expressing sadness to the Funny Plant's poor health. He also asks Golfball and Puffball if they even care about the planet when they begin to smash into his giant form in "Balancing P.A.C.T."

Tree seems to have an odd liking towards death in some episodes, despite being on a team that prevents death. In "Gardening Zero", Tree kills a Funny Plant while wearing an evil smile on his face. In "Fishes and Dishes", after seeing multiple corpses at the bottom of the lake, and witnessing Fanny drown, he does a dance that translates to "No! So much death!", but it’s juxtaposed to him wearing a big grin while saying it. Loves black hole :)
