Cat
The cat has achieved something unprecedented in human history: the transformation of a predatory animal into the internet's primary content category. Cat videos generate billions of views annually, with compilations of felines failing to navigate household obstacles accumulating watch time that exceeds the combined GDP of several small nations. The species has spawned memes, reaction images, and an entire vocabulary of internet communication. One cannot browse social media for fifteen minutes without encountering a cat demanding attention it has done nothing to earn.
Sonic
Sonic maintains a substantial internet presence, though one largely confined to gaming communities, nostalgia forums, and a fan art ecosystem of questionable artistic merit. The character generates controversy approximately once per month, typically regarding new game quality or the disturbing design choices in film adaptations. His meme potential peaked in the late 2010s with the 'Sanic' phenomenon, wherein deliberately poor drawings of the hedgehog achieved ironic appreciation. This represents a curious achievement in which failure became a form of success.
