Snowtrooper is a girl disguised as a Snowtrooper, as revealed in "Arf's Brother Arfy". She is in love with Fox, although her feelings are not reciprocated. This is evident on several occasions, such as in "Happy Valentine's Day!", when she tried to give Fox flowers in she was hit in the face by Fox's rifle. In "The Base 327 Valentine's Day Extrav-O-Ganza", she again tried to give Fox flowers at the "Base 327 Valentines day Extravoganza!". She was violently beaten. As well, in "Arf's Brother Arfy" she was threatened by Fox twice, once with a rocket launcher and once with a pistol. The second time Fox is ready to shoot her when she decides to take off the helmet because it's uncomfortable. It is currently unknown why she was dressed like a Snowtrooper although it may be that she just wanted to follow Fox. After her dramatic reveal as a girl the whole base freezes and two clones pass out. Snowtrooper has obviously liked Fox for a while because one of the signs by the Random Bottomless Pit had a cartoon showing that Snowtrooper liked Fox in "Base 327: The New Guy".
After Fox found out about Snowtrooper being a girl, he returned her love and they dated and got married two years later. The two left Base 327 and moved to Base 711, but eventually came back after Base 711 was destroyed by a rouge clone named, Commander Mcfly. They remained married until they were forced to split when the Empire was created.
Snowtrooper was recrutied into the Empire as one of the many snow assault stormtroopers to be under the command of Imperial General Veers. Snowtrooper was not put to action until the battle of Hoth where she is allegedly seen in Star Wars V: the Empire Strikes Back in the background of General Veers' AT-AT (All Terrain Attack Transport). Snowtrooper then helps Darth Vader break into the Rebel base with the Imperial 501st but secretly escaped the Empire using a jet pack to fly onto the Millennium Falcon and sneak onto the ship. But the ship flew to Cloud City. Snowtrooper hijacked a Tie-Fighter then flew to Darrop IV to find Fox. She landed the ship behind Base 327 and broke a hole right into Red Squadron's room. Snowtrooper and Fox lived happily ever after (like Han and Leia).
But in "Imperial Base 327" Fox and Snowtrooper was not shown together.
After the "Imperial Base 327" episode, Roy (the Newest Guy) found Snowtrooper's Tie-Fighter and took it back to Coruscant. While Fox and Snowtrooper stayed at Base 327 they had a baby named, Harambe. Welcome to the world Harambe!
