A stage hazard, more commonly referred to as a hazard, refers to a particular stage element in Super Smash Flash 2 that can directly interfere with the characters as they are fighting in the middle of a match. Most stage hazards can directly damage and launch characters on contact, like the lava on Phase 8 or the red beams from Lunar Core, while other may be sudden changes or transitions on multiple stages' layouts, like Galaxy Tours or Castle Siege, and sometimes some may be more of a nuisance rather than an actual threat, like the drawers from Desk or the bumpers on Casino Night Zone. Some stages' hazards come in random intervals, too.

Stage hazards can be switched on and off from the Rules menu or stage selection screen, so that competitive players can play on a wider variety of stages — both neutral and counterpick. It should be noted, however, that some stages are still banned in tournaments even with hazards disabled, as their layouts, rather than hazards, may damage competitive play.
