Gekota (ゲコ太 Gekota?, Yen Press: Croaker) 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 Gekora?). 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.
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 Gekota?) 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?, Yen Press: Hoppit) 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.
The Gekota franchise is the most prominent one in the Toaru Majutsu no Index universe, and there has been a lot of various items that feature its characters.
