This is "Gummy King Tahm Kench" by RexSadio. It's one of the many champion skin concepts that League of Legends fans love to post on the game's official forums. It's also a wonderful idea. That's pretty much all I have to say about it.

League of Legends' giant catfish champion Tahm Kench brought a powerful new ability into the game when arrived last week: with or without his teammate's permission, the guy can swallow an ally champ whole and carry them around in his belly for a few seconds. You can probably see where this is going.

Video: Riot just put out its champion spotlight for the upcoming giant catfish champion Tahm Kench. This guy seems so cool! I bet he's also going to lead to so many awful puns about "feeding" in-game thanks to his swallow-other-champions ability.
