Surak is an adult male lion with dark brown fur and a creamy brown underbelly, paws and muzzle. His mane is large and, like his tail tuft, has other, lighter stripes of fur running through it. The mane points upwards on the sides and near the bottom, where a tuft of fur sticks out from it.
He has exceptionally large upper eye rims and eyebrows, compared to his relatively small and thin eyes which are yellow with reddish-brownish irises. Surak has black ear rims along the top of his ears and dark brown ones on the sides, while his inner ears are pink. Surak has a brownish-red, pointed nose and black whiskers. Unlike most lions seen on the show, his black claws are always extended, even the ones on his hind paws.
Surak is rather muscular and stocky, with large front limbs and thinner hind legs.
He is the oldest member of the Night Pride. He has great wisdom and had been instructed by Janna to guide Rani with it. He is shown to be calm and likes to think before he acts, as he told his nephew before rushing to attack the Lion Guard. He is also the more rational and reasonable one of the group.
He has great strength but shows to be calm in battle and do what’s right in various situations. Surak appears to be knowledgeable in lore and legends, as he correctly suspected Kion'sRoar was the Roar of the Elders after first witnessing its power.
Though he is most often stoic and hardly fazed by anything, Surak is not made of stone, as he shed tears at the passing of his mother and comforted his nephew.
After Bunga causes a rockslide that blocks the entrance to the Tree of Life, Rani gets worried that the visitors might be a threat. Ullu leads the Night Pride to the Lion Guard; Baliyo goes up to take a look and starts to attack Kion. The rest of the Night Pride attacks the other members of the Lion Guard. Kion soon uses the Roar of the Elders on Baliyo and sends him flying. Rani gets upset and says that Kion and his friends aren't welcomed at the Tree of Life. The Night Pride goes to check up on Baliyo to make sure that he's okay; they see he's fine but is a little dizzy, much like when Kion roared at Bunga. Surak advises him to think before he acts next time. Later, Rani soon comes back from talking to Queen Janna. She says that Janna has requested to see Kion and his friends. The Night Pride soon finds the Guard and welcomes them to the Tree of Life.
The Night Pride welcomes the Lion Guard to the Tree of Life, where they meet Queen Janna. Queen Janna sees that they have the Mark of the Guard and she knows that they're from the Pride Lands. After Nirmala, their healing expert, checks out Kion and Ono, she reports her findings to the Queen. Janna explains that while healing Ono will be simple, with his remedy being ready in a few days, Kion's ailments will take both time and patience. Wanting to start right away, Kion is led away by Nirmala to begin his healing.
The Night Pride soon encounters Makucha's Army. After being defeated by the Night Pride, Kion and his friends come and crash into them. Rani informs them the villains have been defeated already, pointing they're good at protecting the Tree of Life. Rani tells Kion they don't need his help, coldly telling him to stay out of their way, get healed, and go home. When the Night Pride begins describing the invaders, the Lion Guard recognizes them as Makucha's Army, quickly realizing they must have followed them all the way to the Tree of Life. Kion tries to apologize, though the revelation angers Rani greatly.
Makucha's Army later returns again and fights the Night Pride. Chuluun is seen sneaking up on Surak, while Ora paralyzes Baliyo, weakening the Night Pride. Kion soon arrives and the army is defeated.
The Night Pride is attacking Makucha's Army once again. They are seen chasing Mama Binturong, who is pretending to be a old animal with a broken leg. Rani and Nirmala take her into the Tree of Life to speak with Queen Janna. The next day, Mama Binturong says that Chuluun is chasing her when it's just a trap. Bunga and Binga soon stop her with their stink.
Makucha's Army comes back again, attacking animals at the Tree of Life. Anga brings them and Kion roars on them. He blasts the bad guys away and the animals are safe. After realizing the full power of Kion's Roar, Rani asks to the now healed Kion to stay instead of returning to the Pride Lands.
