Super Mario Bros 5 Reborn is a Super Mario World hack created in 2011 by Gamma V. After saving Peach from Bowser in the Starlights Islands, Mario and Luigi travel to the Kola Kingdom. Unfortunately, while they were gone, Bowser took over the Mushroom Kingdom and sent his Koopalings to steal the Star Keys that bridge the two kingdoms. Now the brothers have to get the keys and take their kingdom back.
It can be found on SMW Central, here. It also received a remake, titled Mario and Luigi: Kola Kingdom Quest, found here.
This game provides examples of:
- Batman Can Breathe in Space: Mario has no problem breathing in the moon-themed secret world.
- Big Boo's Haunt: Worlds 2-6 have one haunted level each.

- Continuity Nod: To other games in the Mario series, including Marine Pop/Star Pop shooter sections and even an area where you can use FLUDD.
