This is artificial lifeform S-61, she was made to test flight units for a flying soldier project.

She can fly at altitude without needing any special equipment however her helmet does included a respirator, on her chest she carriers a special ground radar and GPS system.

Her flight unit uses plasma instead of conventional fuel so she can fly for long periods of time. the fins on her tail and links on her back for the flight unit cannot be removed unlike the rest of her armour.

S-61 is a serious character and doesn't like her sisters messing around.
