The Big O possesses a varied array of weapons. The cockpit includes an assortment of pedals, levers and buttons that control the Megadeus. The weapons are hidden within a Megadeus, so only by displacing certain parts of the armor can the pilot make use of them.
The material that makes up Big O's head ornament and cockpit viewport can deflect beams but it can also crack under pressure. The rest of Big O is covered in heavy armor plating, reflecting its function as a land unit required to survive heavy combat. The heaviest armor is on the arms for charging attacks.
