Road Attackers

The Road Attackers (ロードアタッカーズ) are a Reploid bōsōzoku that appear as enemies near the end of the Opening Stage in Mega Man X. They have 2 stages: 1: robots driving the cars. 2. Non-moving cars. They're deployed from the Death Rogumer, the same airship that Vile emerges from in the end of the stage.

The Road Attackers drive modified red cars equipped with a large cannon in the hood and pursuit X, attacking by firing the cannon and trying to run over him. When the driver is destroyed, X can stand on the car. Depending on how much damage it receives, the vehicle will continue moving ahead, stop, then break. It is not possible to ride the cars in the remake Mega Man Maverick Hunter X.
