Dressed as his favorite superhero, Indonesian teenager Rudiyansah walks along a charred landscape, helping douse wildfires that have razed large parts of Borneo island.

The Southeast Asian country has been battling infernos that have left a thick, blanketing smog over parts of the island that Indonesia shares with Malaysia and Brunei.

Rudiyansah’s red and blue Superman costume stood out against the stark, scorched landscape surrounding the town of Palangkaraya, where he has joined a local volunteer firefighting group set up by his father to put out smoldering peatland.
