Lector

Lector (レクター Rekutā) is an Exceed and a Mage of the former strongest Mage Guild in Fiore: Sabertooth.

Appearance
Being an Exceed, Lector's appearance is that of a small, mildly anthropomorphous cat standing on his rear legs, with his two front legs acting as hands of sort. His fur seems to be dark brown in color, with most of his body being red, but his face, belly, paws and the end of his long tail being pink. He has large, pointed ears, and prominent tufts of dark fur jutting outwards in correspondence to his cheekbones, where his whiskers are.[4]

Lector doesn't don a complete outfit, instead sporting just a blue, sleeveless button-up vest which is left open, and has three dark round buttons on its right side.

Personality
Lector is a highly arrogant cat. He has a habit of belittling others, considering everyone to be beneath Sting, and, in general, beneath the Sabertooth guild as a whole. During the Grand Magic Games, he constantly states that Sabertooth members will easily win their matches, even berating Frosch for simply asking who would win. When things don't go as he foresees, Lector is left in a stunned state, best seen when Yukino Agria was easily defeated by Kagura Mikazuchi and when Sting simply quit the race he was in.

Upon seeing Sting and Rogue, the two Dragon Slayers Lector constantly praised for being true Dragon Slayers, being single-handedly defeated by Natsu with relative ease, Lector was left speechless and distraught.[8] However, it appears that Sting's loss has humbled Lector, having told Jiemma that even though Sting lost, he learned more from his fight in defeat rather than in victory, seemingly changing his arrogant ways.

History
After seeing Sting fight for the first time, Lector followed Sting and begged him to allow him to become his student. Sting was confused as the why Lector wasn't scared of him, but Lector claimed he just wanted to become strong. Sting admitted it would be weird to have a cat as a student, but told Lector to follow him anyways.

Several years ago, Lector began to brag to others about how his friend Sting killed a Dragon on his own. However, no one believed him and others even started saying bad things about Sting, which greatly upset the little Exceed. As he was crying, Sting put his hand on Lector's head and promised that he would defeat a man named Salamander.
