Hae-jin is a tall, muscular boy. He has tanned skin, spiky, curled dark gray hair, and red eyes. He has a one-sleeved black sweatshirt, red pants and red shoes with yellow overlays. He also wears dark-yellow armor plating with silver borders on his waist and left shoulder.
Although he's usually quiet, Hae-jin is friendly and quite gentle to his friends. He is also very supportive and kind to Aiger and Naru. This is shown when during his battle against Aiger in the semi-finals, he refused to let his trainers take him back to Korea, as he knew that if he do it, Aiger would be sad and disappointed as he was excited for their match. By the expressions he makes with his face, he isn't used to smiling or laughing but later he became able to do so, as he had so much fun with Aiger, Naru and the others.
Aside from this, Hae-jin's biggest fear are snakes, though it is unknown how or where he developed this fear from, and is revealed when Naru told him that he will battle Dhaula Giri from India and carries a snake tied around neck like a scarf.
The drinks that he also makes taste slightly nasty for others sometimes, like when he made a healthy smoothie for Naru, Aiger, and Ranjiro and allowed them to drink it. After tasting a bit, the three didn't like it and vomited 1-by-1.
Hae-jin is an archer and a Blader who comes from Korea. It's shown that he has much strength that during the eliminatories that he broke the Power Test Machine, being able to participate in the Lúinor Cup. He later met Aiger and Naru and quickly became friends with them, as he learns more about Beyblade and using his archery skills as his launching form.
