Machinda is an enemy that appears in some Bomberman games. It is a combining mecha that links up with other robots of its type.
Machinda moves slowly, pursuing the player. When a player lines up with it horizontally or vertically, even if there are walls or bombs in between it and the player, the Machinda will move more quickly. It will also speed up if a player comes within a 3x3 tile range.
When two Machindas come in contact with each other, one will pause while the other hops onto it and connects with it. They will then both move together in pursuit of the player, one following the other. There does not seem to be a limit for how many Machindas can link up. When the Machinda chain is hit by an explosion, each robot quickly scatters in a diagonal direction. If a scattering Machinda lands on an empty space, it will resume its normal behavior; otherwise, it will jump to another space, randomly moving in a diagonal direction.
A Machinda can only be damaged if it is not linked up or scattering. It will harm players on collision.
