|Mars Brain Robot|
|"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, its 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 its normal attacks. However, it lacks the ability to deal critical hits, something which its Invader counterpart is capable of doing.
