Editing Stage hazard

*'''Trapdoors''' are sections of the stage that can give way and reappear over a character, which usually makes returning to the stage difficult or impossible. For example, [[King Bulblin]] on the [[Bridge of Eldin]] can destroy the bridge, and players can be trapped below when the bridge is later reconstructed. Another example of a trapdoor hazard is the [[Drop Block]] in one of the default [[custom stage]]s in ''[[Brawl]]''. Trapdoors differ in terms of how they are triggered; some automatically open and close at timed intervals, some open based on proximity (with a delay before opening) and then automatically close sometime later; and still others have to be manually triggered (such as by taking damage) in order to open.

*'''[[Stage transformation|Transformations]]''' create a situation where the character can be caught under or off to the side of a stage because of a sudden shift in the stage. For example, the [[Frigate Orpheon]] stage can cause players to accidentally self-destruct when it flips upside down, and [[Orbital Gate Assault]] features many sudden transitions from one group of spaceship platforms to another. These should not be confused with trapdoor hazards; the difference is that trapdoors are located in specific portions of a stage, whereas transformation hazards specifically feature a (near) global change in the stage.

*'''Predators''' will pursue the players and attack them. Some examples include the lookout cannons on Pirate Ship and the Arwings and [[Wolfen]] which swoop in and fire lasers around characters on various {{uv|Star Fox}} stages. These sometimes overlap with blast hazards, such as the Combo Cannon on Halberd.

*'''Vehicles''' may occasionally speed through some stages, causing damage and knockback to characters that collide with them. A warning or environment cue that a vehicle is approaching is usually given, such as a flashing exclamation point on [[Onett]], or the vehicle can be seen from far away before arrival, such as the racers on {{SSBB|Mario Circuit}}. Vehicle collisions may also trigger explosions on certain items. Vehicles are similar to mobile static hazards in that both pose a threat by slamming into fighters; the main difference is that vehicles briefly pass through the playable area at various intervals, while static hazards are either always onstage or remain onstage for extended periods of time, and vehicles also usually move quickly and warn players before their appearance, while static hazards can appear abruptly and usually move slowly (if they move at all). Vehicle hazards are not necessarily actual vehicles; anything that periodically rushes through the stage and damages fighters in its path, without lingering onstage for more than a few seconds, fits this hazard archetype. A good example is the Peckish Aristocrab in the [[Garden of Hope]] stage, which does not fit any conventional definition of the word "vehicle", yet has all the properties of a vehicle-type stage hazard (dashes through stage periodically and inflicts damage and knockback to all fighters it collides with, has a clear warning of its imminent arrival before threatening fighters, does not remain on stage for a prolonged period of time).

*'''Illusions''' are designed to affect the players themselves rather than the character, although they can sometimes lead to disorientation and self-destruction. [[Palkia]] on Spear Pillar can tilt the screen's orientation of the stage and invert player controls by mirroring the stage.

*'''Enemies''' generally appear as a species and can obstruct the player or cause knockback and damage. Enemies are similar to static hazards, but most enemies can be damaged and defeated or can be grabbed and thrown. One example of an enemy hazard is the [[Polar Bear]] in Icicle Mountain.

*'''Monsters''' are large enemy species that cannot be defeated and can KO a player when hit, grabbed or swallowed by. Some monsters include the [[Ultimate Chimera]] on [[New Pork City]] and the [[fish]] on [[Summit]]. While the [[Peckish Aristocrab]] on [[Garden of Hope]] exhibits characteristics of a vehicle hazard, as previously mentioned, it is also considered a monster by virtue of being a large, hostile living being that is immune to all attacks from the fighters.
