The protagonist of The Last Guardian, so far only known as the boy, is a young human boy from a tribal village somewhere in the world. He looks to be slightly younger than Ico. Pursued by many enemies, the Boy must work together with Trico, a huge hybridized beast, to escape the world they awake in.
Looking to be a boy of about ten years old, he stands at a typical height for that age (around 1.3 meters/ 4.5 feet) and has dark hair, dark eyes, and olive skin. He wears a white and black robe with an orange shoulder piece. One of his most distinct features are the intricate tattoos all over his arms, torso, and neck, with a few markings on his face. The Boy did not have these marks before being taken from the village; rather, these tattoos first appeared when he was regurgitated by Trico, and increased in complexity every time he was regurgitated.
The boy wakes up in a strange cave next to an enormous, injured beast named Trico. After the boy compassionately treats the beast and feeds him, the two set out together to find a way out of the catacombs, only to emerge into the world above, a massive inescapable valley called "the Nest," filled with rotting castles, temples, and dizzying bridges.
It is revealed that the Boy, along with countless other children, was kidnapped from his village far away from the Nest by Trico himself. It was meant that he be brought back to the Nest to be consumed by Trico's evil master, a being known as The Master of the Valley. However, the control was fortunately broken over Trico, allowing the beast to bond to the Boy and become his guardian.
Combating enemies along the way, the Boy and Trico find their way to the Citadel, the tallest tower in the Nest where the Master resides and destroy it. Trico returns the boy to his home village and the two part ways. The Boy, now grown into a man, concludes the telling of their "extraordinary story."
The boy, while prone to fear like any human, is very courageous, curious, and compassionate. He bravely battles his way through the challenges, even without Trico to help him in some cases, he cleverly solves the many puzzles, and he always cares for his giant, feathered friend. This comes in the form of finding food when Trico is hungry, removing spears from his hide, and calming him after a battle, or even just giving him affection.
Powers and Abilities
- Trico's support: Being a mere boy, it is largely up to Trico to use his strength, talons, and ferocity to combat enemies like Knights and Armored Tricos. However, the Boy can assist Trico in a fight, whether by releasing him when his tail gets stuck under a gate or driving away an Armored Trico by dropping heavy objects on it. He can also headbutt and knock over Talisman-wielding Knights
- Small size: Trico often has trouble traversing the tight tunnels and corridors in and under the Nest, but the Boy has no such encumberment. This allows him to open doors and solve puzzles to allow the two to progress.
- Cleverness: Trico seems to have basic intelligence, and he can even give the Boy hints, but it is up to the Boy to solve puzzles so the two can move through the world.
- Talisman Immunity: For all his size and ferocity, Trico cannot approach these strange apparatuses, but the Boy can remove these obstacles for him by knocking them over, breaking them, or cutting their supports, making them fall and shatter.
- Healing/Feeding: Trico seems unable or unwilling to hunt for food or remove spears from his hide after a fight. Going hungry or being injured often leaves Trico unable to progress. However, the boy can find Barrels to feed him or climb up to remove spears.
- Lightning Attack Targeting: While it is Trico's tail that can summon powerful lightning to destroy objects, it cannot happen unless the Boy directs the Mirror's light at the desired target. This puts a lot of firepower in the Boy's hands.
Of particular interest are the many tribal tattoos covering most of his body, including the back of his hands and fingertips. These tattoos, which resemble the tattoos of the Māori and Samoan people, suggest the boy may have come from a similarly tribal village.
It is unclear what the boy is doing amidst the complex ruins and stone towers when Trico first encounters him. We do know that he is being pursued or otherwise trying to avoid being caught by a number of Armored Knights and must escape by either sneaking past the knights, or dealing with them more directly. Trico, who is seen effortlessly dispatching one such knight in the trailer, will likely be of help many times in this respect alone.
