Modules are the robots you use to fight in battle.  Each module has their advantages and disadvantages.  Small, Medium, and Large represents the sizes of weapons these modules can carry.  Small means they can handle small weapons, Medium means they can handle small and medium weapons, and Large means they can handle any size weapons.  Pocket Size is the amount of stuff they can hold.  For example, if the Pocket Size is 4, that means the module can hold up to 4 weapons/shields, 4 optional weapons, and 4 fields.  Attack Type tells you the specific types of weapons these modules can handle.  There's Impact, Laser, Beam, Heat, and Special.

 This module excels in running around and dodging attacks, but it's not so good when it comes to strength and taking damage.

 Saurus may not be well balanced, but he's great for staying in the back using long distance weapons. He's the only module with 5 Melee points. What makes Saurus even better is that it can equip "Special" weapons.
