Orc enemy line

Orc, Orc Captain and Orc Lord are species of monsters found in Golden Sun. These monsters, resembling muscular pig-like humanoids armed with scimitars, are palette swaps of each other and have differing levels of power and defense. This is one of few monster lines where none of its members appear in Golden Sun: The Lost Age, at least as random encounters.

Orc
An Orc is a member with pink skin and blue pants. Orc features 148 HP, 156 Attack, 41 Defense, 54 Agility, and 3 Luck. It is most resistant to Venus-based attacks, evenly resistant to Mercury and Mars, and weak against Jupiter.

Orc can attack physically and use the monster skill Spasm, which restores some of its HP.

Felling an Orc yields 68 EXP, 113 coins, and sometimes a Nut. They are only fought in Lamakan Desert.

Orc Captain
An Orc Captain is a member with light orange skin and green pants. Orc Captain features 231 HP, 248 Attack, 69 Defense, 90 Agility, and 4 Luck. It is most resistant to Venus-based attacks, evenly resistant to Mercury and Mars, and weak against Jupiter.

Orc Captain can attack physically, defend, and use the monster skills Spasm and Stand Ready. It also carries a Smoke Bomb, which may inflict several targets with delusion.

Felling an Orc Captain yields 125 EXP, 142 coins, and sometimes a Smoke Bomb. They are fought in Suhalla Desert and much of the world map area beyond Gondowan Passage.

Orc Lord
An Orc Lord is a larger member with light purple skin and red pants. Orc Lord features 278 HP, 18 PP, 302 Attack, 98 Defense, 70 Agility (oddly 20 points less than Captain's), and 3 Luck. It is most resistant to Venus-based attacks, evenly resistant to Mercury and Mars, and weak against Jupiter.

Orc Lord can attack physically, use the monster skill Spasm and use the Psynergy Sleep, to put multiple party members to sleep.

Cultural Allusions
Orcs are a popular creature in the fantasy genre, particularly in the stories written by the late English writer John Ronald Reuel Tolkien (best known for titles such as The Lord of the Rings, which also features Orcs). They're often described as tough, warlike humanoid creatures with faces that resemble a cross between a pig and a primate.
