Gekota

Gekota (ゲコ太) is a popular mascot found in merchandise marketed to children in the Toaru Majutsu no Index universe. A Gekota fan is called a Gekoer (ゲコラー). Misaka Mikoto is a huge fan of the franchise it belongs to, and much to her consternation gets her labeled as someone who is childish.

Principles
Gekota seems to belong to a cast of characters composed of frogs. Several characters have been revealed to exist in the franchise so far.
 * Gekota (ゲコ太) is an old man type of character who is known to suffer from motion sickness easily. Because he has a habit of saying geko-geko (ゲコ, ゲコ), the name stuck and he's been referred to as such ever since.
 * Pyonko (ピョン子) is a female frog from the same franchise. She wears a bow on her head and is pink in color in contrast to the usual green of the male frogs.
 * Keroyon (ケロヨン) is another frog from the same franchise. He lives next to Gekota. His name is revealed in Dengeki no Kantsume (電撃の缶詰) vol.159.
 * Pyonkichi (ピョン吉) is another frog from the same franchise. He appears in Misaka Mikoto's dream when she used Indian Poker.
