23. Greninja’s overall appearance is based on a frog, and it may have been inspired by horned frogs from the genera Megophrys and Ceratophrys due to the spiked protrusions above its eyes. Its color scheme and body shape is similar to that of the splendid leaf frog. The bubble-like protrusions on its body may be based on a toad’s parotoid glands, possibly referencing the traditional myth of toads causing warts, though they may also be remnants of Froakie and Frogadier’s frubbles.

Japanese culture associates frogs and toads with ninjas based on the folk story “The Tale of the Gallant Jiraiya” (児雷也豪傑物語 Jiraiya Gōketsu Monogatari) about a ninja who can shapeshift into a large toad.
