Thinkers are the player character of Kainga. They are the only unit capable of discovering new technologies, (generally) cannot fight, and must survive in order to succeed on a mission. They can be found in the Skyloft when not playing a mission.
Wise with experience, this Thinker considers the future of his people carefully. Expect an early establishment with the resources needed to get a head start. — Kainga Encyclopedia
Sumac is the newest Thinker to join the Skyloft. He was tasked with finding 6 relics across the lands: a fossilized skull, a Darkwood branch, a teal pearl, Trunkwood sandals, the royal sash and a seeing stone. After having spent his entire life looking for these items, he was given the impossible task to "build a town on a Crustacean". During the tutorial segment of Kainga, Sumac accidentally awakens a Crustacean granting his acceptance into the Skyloft. After having arrived, he wonders why no others had to go through such a difficult journey to become a Thinker... — Thinker Deep Dive: Sumac
Sumac is the first Thinker available to the player upon starting Kainga for the first time. The player takes control of Sumac during the tutorial of the game, walking through his final steps in his journey to be elevated to the Skyloft as a Thinker. His starting resources and Feast festival help support a burgeoning village, and the Structure Safety passive makes building placement a bit more forgiving. He otherwise has no other unique features or gameplay quirks to be aware of, making him a very good Thinker for the beginner player.

Garam
This Thinker's mind darts from one activity to another. Speed and combat strength are assured at the start, but a wary mind lingers to festivities. — Kainga Encyclopedia
Garam was welcomed to become a Thinker after his father, the great woodworker, constructed the Skyloft for the other Thinkers. Garam sees himself as a diplomacy master but is quite hot-headed and his attempts at negotiations lead to combat just as often as friendship. Being quite young, Garam was worried his followers wouldn't take him seriously, so he fashioned an impressive fan on his back which he tells his followers allows him to fly! — Thinker Deep Dive: Garam
Garam is a very fast-moving Thinker, who starts each mission with two Warriors and the incredibly powerful Sharpened Axes passive technology. The combat prowess of his Braves has a leg up on others, in some cases negating the need for Combat technologies at all. Starting with Garam can be difficult, as he starts with no food and only three Braves. Two of his festivals require fabric, and he doesn't start with enough to build the Skylamp Festival. This all but necessitates using one of his Resource inspirations on a fabric-producing technology, which may or may not appear in the list. (Alternatively, remembering a technology such as the Lotus Pond makes this trivial.)
Of note, Garam cannot fly using his fan, but he does move faster than all other Thinkers.

Achiote
Accompanied by his protector, this small Thinker uses strength to get ahead. Slow but able to fend for himself, this Thinker dreams of construction. — Kainga Encyclopedia
Achiote, being a royal, was promised Thinkership before he was even born. He accepted at a very young age and thus became immortalized as a child. It was agreed that Achiote could be accompanied by a "guardian" and so the blind guard guides this little Thinker everywhere. Now, unfortunately, Achiote regrets accepting being a Thinker at such a young age as he deems his own body useless... — Thinker Deep Dive: Achiote
Achiote is accompanied at all times by his guardian, who has not taken the same oath of pacifism as all Thinkers must. This means Achiote is able to defend himself when necessary, unlike all other Thinkers. However, because his physical body is so small and vulnerable, once the guardian is defeated Achiote is banished as well. The guardian moves more slowly than any of the Thinkers, including Kala when not riding Jeera. Achiote begins missions with more Braves than others, and his festivals are centered around resource creation and construction. Blessed Scaffolding lets his Braves build any structure—even if they lack the resources to do so.
