Super Onion Boy 2

Super Onion Boy 2 expands on its predecessor's retro-platformer charm with a bigger scope: vibrant levels, superpower transformations, and a rescue-mission story that sends you after a friend held captive by a powerful beast.

The transformation mechanic adds real variety to the platforming — different superpowers open up different approaches to obstacles and enemies, so experimenting with which form suits a given section becomes part of the fun rather than a side gimmick. Uncovering hidden treasures along secret paths rewards players who explore beyond the obvious route.

Formidable bosses punctuate the adventure at key points, testing whether you've learned to use your transformations effectively rather than just relying on basic platforming skill. These fights typically demand a specific approach, making boss encounters feel distinct from regular level traversal.

Super Onion Boy 2 is a strong pick for platformer fans who enjoyed the original and want more scope, more powers, and bigger stakes. Play free instantly in the browser, no download needed.
