Lore / Story involvement

A medium size mechanical vehicle of Sangvis Ferri origin, Prowler unit can be identified by its oculary sensor fitted on the head region and four mechanical limbs that forms the quadrupedal appearance, movement relies on wheels. An automaton unit with relatively lower mobility, they are typically used for friendly sector monitoring or scouting operations.

After Butterfly event and the Sangvis Ferri command chain overhaul, Prowler are now being used as a combat unit, individual combat performance are considered trivial compared to Sangvis Ferri Humanoid type androids. They are equipped with a moderate-short range projectile type weapon fitted on the head, the head region also provides storage for unit ammunition, such storage space however cannot store anything else.[1]

Using Architect as scale reference, the size of a Prowler head/turret should measure around 40×40×50 cm in size, while the chassis should be around 60×60 base width when contracted and no more than 120×120 with the legs fully expanded.
