In-Game Description
"The Brain Robot was improved by the Professor using the knowledge gained on Mars. It was thrown into the battle with the Rebel Army to test its performance."

The Mars Brain Robot is a unit original to Metal Slug Attack. The standard Brain Robot was improved by the Professor, giving it better combat capabilities than its Invader counterpart. It first appeared in the Extra Ops titled "Signal Red". As this event has ended, it's parts are currently unavailable.

Like its Invader counterpart, the Mars Brain Robot has good damage output but low health. It attacks much faster and deals heavier damage with it's normal attacks. However, it lacks the ability to deal critical hits, something which its Invader counterpart is capable of doing.

Its special attack also deals multiple high-damage strikes in rapid succession, and with MSA Skill small + 4 unlocked, furthermore has stunning potential. The range is sufficient to reach many back-line enemies.

When the Mars Brain Robot and a Ring Laser Mecha(Red) are placed in the same deck, they form the "Mars Elite" team. This lowers their AP costs by 10%.
