'''Arena Ferox''' is a stage in ''[[Super Smash Bros. for Nintendo 3DS / Wii U|Super Smash Bros. for Nintendo 3DS]]'', based on the area from ''[[fireemblem:Fire Emblem Awakening|Fire Emblem Awakening]]'' of the same name. The stage takes place on a platform in the middle of the arena with edges on both sides, making it an aerial stage. The stage's main gimmick are the platforms that take different forms at various times of the match, a gimmick similar to the [[Pokémon Stadium]] and [[Pokémon Stadium 2]] stages from past games. There are four different variations of the stage, one variation showing four pass through platforms, the bottom one having a wall supporting it, the second variation having two statues holding up three pass through platforms, similar to the second area of [[Castle Siege]] from ''[[Super Smash Bros. Brawl]]'', the third variation showing multiple floating platforms, three of which can be passed through while the other two are solid and the final variation showing a pass though platform at the far right, a solid platform in the middle and a moving platform at the left, which moves in a rectangle shape by a mechanism.
The [[Final Destination]] version of the stage is mostly unchanged, though the stage does not shift form at all, instead taking place entirely on the flat arena.
