Ω form

Ω forms (Omega forms, also known as Final Destination forms) (終点化, lit. Final Destination forms) are alternate versions of stages in Super Smash Bros. 4 and Super Smash Bros. Ultimate which modify them to have a Final Destination-like layout, consisting of a single flat platform with all stage hazards removed. Pressing the X button on the stage select screen in the 3DS version of Smash 4 will fill the circular cursor with either 終点 (Japanese), Ω (other languages) or DF (PAL French version, 3DS only), allowing Ω Form stages to be selected. There is also an option in the rules to have the game automatically select Ω Form stages at random; this is how stages are selected in For Glory mode. Ω Form stages can also be selected at random by pressing the X button and selecting Random on the stage select screen. Final Destination itself can be selected as an Ω Form stage, but this doesn't change its layout.

Omega Forms will return in the upcoming Super Smash Bros Ultimate, and will be accompanied by a new option that modifies stages to have a Battlefield-like layout.

Differences

Smash 4

Ω Form stages are not all functionally identical, as the shape of the platform's underside varies, with some stages having walls all the way down to the lower blast line. This can have a significant impact on characters' recovery, especially those with the ability to wall jump; for example, Little Mac gains a tremendous advantage on an Ω Form stage with walls; despite his notoriously weak recovery, he has a very strong wall jump, aiding his recovery significantly. This advantage, however, is strangely not applicable to Pac-Land as it is impossible to wall jump, despite the presence of walls.

Certain Ω stages also have top blast lines at slightly different heights compared to Final Destination. Ω Battlefield, Duck Hunt, Hyrule Castle, Jungle Hijinxs, Kalos Pokémon League, Luigi's Mansion, Lylat Cruise, Onett, Pokémon Stadium 2, Skyloft, Temple, Town and City, Umbra Clock Tower, Suzaku Castle, Windy Hill Zone, Castle Siege, Boxing Ring, Gamer and Midgar all have lower blast lines, while Halberd, Coliseum, and Palutena's Temple have higher blast lines. However these differences are far too minor to realistically affect gameplay, with the exception of Pokémon Stadium 2. Ω stages with grass along the platform where battles occur also increase characters' traction, with the exception of Super Mario Maker.

Also, most Ω Form stages have Star KOs and Screen KOs enabled while others don't.

Ultimate

In the introduction of Ω Form and Battlefield-form stages in Ultimate, Masahiro Sakurai stated that they differ only in music and aesthetics. Unlike in Smash 4, the terrain and blast lines no longer vary between stages.

Tournament legality

There is some debate on how Ω Form stages should be handed in competitive play. Those who opt for the ban of Ω Form stages note how not all stages are the same, as mentioned above. This means that recoveries and stage-spikes would be massively different, and the different stages' blast zones could create unforeseen variation in when characters are KO'd. However, in practice, Ω Form stages are usually treated as equivalent to Final Destination.

Ω Form stages were notably banned at EVO 2015, although this was primarily because of copyright reasons involving the rights to stream music played on certain stages.

Trivia

• The E3 2013 Developer Direct showed footage of Mario, Mega Man and Wii Fit Trainer fighting on Battlefield Ω before the official announcement of the Ω Forms of stages in the Super Smash Bros. Direct.
• Suzaku Castle is the only stage to retain interactive elements from its original form in its Ω Form, as the signs that appear behind the fighters can still be destroyed.
• When playing with more than 4 fighters on a stage's Ω form, the stage will be scaled a bit larger. However, the stage will not be scaled larger when playing with more than 4 fighters on a Special Orders battle.
