His appearance is somewhat the same as the other forms of BoBoiBoy with cropped black hair and the regular physique of a child, but BoBoiBoy Thorn possesses green irises and is clad in mostly green and black with his cap being fully black with a minor addition of neon green vine-like linings adorning the sides of his cap all the way to the bill. He wears the said cap with the bill turned to the left of his head. Unlike the other elemental split personas, BoBoiBoy Thorn does not appear to sport a jacket but instead, he wears a short-sleeved shirt with black coloring the upper part and green on the lower part of the shirt, with green pants adorned with black jagged, thorn-like linings at the sides. His shoes are a mix of green and black colors laced with white shoelaces. His insignia is placed at the front of his shirt, right under the hoodie. Accessories that mainly differentiate him from the other forms happen to be the green thorn-like studs on a green wristband worn on his left wrist and a black arm warmer (adorned with green studs) that covers all the way from his right forearm to his hand. In BoBoiBoy Movie 2, he has an appearance similar to that of his previous incarnation with a few differences. His jacket is now a stormbreaker jacket with gold laces, the front of his pants are green with thorn patterns while the back of his pants are black with glowing green thorn patterns. His shoes are a mix of green and black colors laced with gold shoelaces. He has two black fingerless gloves with the hems around the fingers being trimmed with green, one worn on his right wrist and the other is covered with a black arm warmer (adorned with green studs) that covers all the way from his left forearm to his hand. The "horns" of his cap are yellow. In BoBoiBoy Galaxy (Season 2), his jacket no longer has gold laces. Much like his base form, Thorn shares much of his personality with Leaf, being a naive and childish individual, though unlike Leaf, he seems to take fighting a bit more seriously now and hasn't been seen going off or getting distracted like Leaf has.
