"Garr is a member of the guardian race, and has been the victor in the Contest of Champions years running. When he meets Ryu, he seems intrigued by his dragon abilities and seems to know more about the ancient Brood than he lets on at first. Garr's attack power is like no other, and he has HP to burn, making him the heavy artillery of your party. He acquires a wide set of fire spells, but doesn't have the intelligence level to put them to good use. Besides that, though, his only downfall is his low agility."
Garr is a main character within Breath of Fire III. He is a Guardian, a race created by the goddess Myria. It is recorded at Angel Tower that Garr killed 299 Brood during the war, the most of any of the Guardians enshrined there.
The long-standing Champion of the Contest of Champions, Garr is one of the Four Guardians created by Myria, the Goddess of Destruction, to eliminate the Brood from the face of the Earth. He, along with his brethren Guardians Gatz, Gaw and Gaist, slaughtered the Brood, who put up no real resistance.
Ryu and friends first meet Garr when they reluctantly enter the Contest of Champions. Ryu, unfortunately, makes it to the final round, only to having to fight Garr. Garr ultimately defeats Ryu and wins Ryu and friends to save them from Balio and Sunder. Fed up with Balio and Sunder's treatment of Ryu, Garr resigns from their service and kills them in their fusion form, with help from Ryu. Afterwards, Garr takes him to Angel Tower in an attempt to execute him and finally eradicate the Brood. However, Ryu defeats him handily, as Garr anticipated, and brings his guilt and doubt that he had bottled up for centuries since the war's end to light. He knew the Brood could have eradicated him and the other Guardians had they wished, yet they allowed themselves to be destroyed.
In the game's second half, Garr finds Ryu hiding in Dauna Mines. Begging for his forgiveness, Garr takes him to see Myria to ask why the Brood needed to be killed. While in the mines, Garr and Ryu encounter Dragon Zombie, who tries to encourage Ryu to kill Garr, but Ryu refuses, starting a fight with Dragon Zombie. Later on, they reunite with Nina and explain the situation about Rei to her. After the group reunites, they head to Angel Tower in order to confront God, only to find that they needed to free Deis from her prison. After meeting with Gaist, they learn that Ryu has to kill him in order to free Deis. After Ryu does so, they head back to Angel Tower, where they meet up with a naked human Deis. Garr is comically beaten up by her before she instructs them to meet her at her shrine at Mount Zublo. There Ryu and Garr learn how to find God.
Later on, Garr is shocked to find out the remaining members of the Brood (all who gave up their powers) forgive him for his actions. This heavily confuses him, causing his guilt to almost overwhelm him. He, Ryu, and Nina confront the leader of the clan, Jono, for information, learning the history between the Brood and Myria, where Garr unwittingly insults him, forcing Nina to take over the conversation. Ryu, Nina, and Garr end up fighting Jono's dragon form in order to obtain the Infinity Gene, but kill him in the process. This helps prepare Ryu for the final fight with Myria.
After the final confrontation with Myria, Garr's powers runs out, and he turns to stone, leaving the rest of the group to escape the crumbling Station Myria before it's destroyed.
Garr's use in battle is extremely straightforward. His only marketable traits are an incredibly high rate of attack power and a good amount of HP and defense (the latter abilities making him a "tank"). His other abilities are below average at best. His magical skills are negligible; his spells are moderately useful, but an abysmally low amount of AP makes it nearly impossible to use his spells to any real effect. Couple this with a very low speed makes Garr a character with a highly specialized purpose. He can be difficult to use, but with appropriate training under certain masters, he can either be a lumbering titan or a trotting behemoth. He is also handy when he learns the skill 'Gambit', because at that point in the game, if it hits, decent damage in the 200-300 region should be dealt. Garr has a natural resistance to fire, taking only half damage from any and all related fire-based attacks and spells. Inoculating him or giving him fire-resistant armor will render him entirely immune to fire.
Garr is faced as a boss twice during the course of the game. The first battle, in the final stage of the Contest of Champions, is not winnable. He is later faced again as he turns against Ryu in Angel Tower.
