The Maple Leaf is the largest of all the Guardians. A fact made more obvious when he "grows" infinitely larger as the need arises. His body is composed entirely of wood; essentially he is a living breathing maple tree. Large roots that shoot from his feet enable him to secure himself to any surface by penetrating and forming a foothold. His branches can stretch from his forearms allowing him to snatch up the enemy or grasp innocent victims in harm’s way. He fires sticky "sap" bombs from his fingertips that trap his opponents like an insect in amber.
On top of all of this, the Maple Leaf has the super ability of chlorokinesis, basically allowing him to communicate with the plant world. The Maple Leaf, or “Trunk” as the rest of the Guardians know him, is one of the funniest of the Guardians. Always quick with a joke or a sarcastic barb, the Maple Leaf often disarms his opponents by bringing levity to tense situations. Don't let the funny man routine fool you though, because when angered this Guardian can be particularly brutal, and this is no laughing matter.
We've got to find a way to win a game. He's played well in the minors, now he gets his opportunity. We tried [with Jonathan Bernier]. The way I look at it, you get opportunities and you make the most of it. That's what [James Reimer] did. Now another opportunity is here and Sparks ... you gotta grab it. Is he ready? We'll find out.
