Winter is Red Eye's pet dog, living with him in Fillydelphia.
Winter was first mentioned over Red Eye's radio broadcasts as being his/a young colt's best friend. Winter's origins are uncertain, he was possibly a dog that grew up with Red Eye in Stable 101 and was eventually converted into a cyberdog as he grew older and his body failed him.
Littlepip encounters Winter during her escape from Fillydelphia, Xenith informing her that Winter was tracking them via their scent. She spots Winter and remembers Red Eye's broadcasts, mentioning him, soon afterwards.
Winter along with several griffon mercenaries, cornered Littlepip on the rooftops where the Pinkie Pie balloons were stored. Winter was scared off by Pyrelight who had soaked up an intense amount of radiation and was much larger than normal when she flew overhead.
Winter's fate afterwards is unknown, he possibly died during the battle for Fillydelphia between the Enclave and Red Eye's forces or perished before that during the destruction of Red Eye's Cathedral.
