Bacura

Bacuras ( Bacura) are enemies from the game.

Origin
Bacuras are rectangular spinning enemies that appear in the Xevious series, where they would act as an obstacle that the player must avoid, as they could not be damaged by normal means. Bacuras have also appeared in other games developed by Namco as special easter egg enemies, similar to their appearance in Smash Run.

In Smash Run
Bacuras appear as enemies. Like their Xevious incarnations, Bacuras are invincible and head straight down. They are invincible obstacles which appear in groups. Touching one deals 4% damage and inflicts a meteor smash. They also can reflect projectiles sent at them.

Trivia

 * A rare glitch can happen where if Bacuras spawn right before entering a Challenge Door, they will try to spawn inside the Challenge Room. Since they are not supposed to appear in Challenge Rooms due to their indestructible nature, the game will simply crash.
