Team SSSN (pronounced "Sun") is a  team of students from Haven Academy in Mistral. The team is composed of Sun Wukong, Scarlet David, Sage Ayana and Neptune Vasilias.
Fall of Beacon, Sun left his team to follow Blake Belladonna. It is unknown if the team was active without him.
After the Battle of Haven, Sun and his team decided to transfer to
Shade Academy in Vacuo, where they help Team CFVY hunt the Crown.
Coco Adel finds Team SSSN to be a mediocre team of Huntsmen, primarily in fault due to Sun Wukong's lack thereof leadership to serve as a glue between them, unlike Team CFVY which is a unified group.
Sun Wukong is the leader of Team SSSN.
Scarlet David is a member of Team SSSN.
Sage Ayana is a member of Team SSSN.
Neptune Vasilias is a member of Team SSSN.
Scarlet, Sage and Neptune are all known to take design cues from members of the K-pop boy band Big Bang, specifically G-Dragon, Taeyang and T.O.P.  
 Team SSSN was planned very early on, even before Team JNPR.
 Before Sage and Scarlet make full appearances, SSSN can briefly be seen after Pyrrha and Mercury's fight in " Extracurricular", just before Sun breaks off to join Team RWBY. Sage and Scarlet make their first full appearances in " New Challengers...".
Just like the other significant characters in the series, each of the members of team SSSN is based on characters or people from classic tales.
Sun Wukong is based on the monkey king, Sun Wukong, from the classical Chinese novel .
Journey to the West Scarlet David is based on the character Peter Pan from , the official sequel to the original Peter Pan in Scarlet .
Peter Pan Though it is unknown which specific character was the inspiration for Sage Ayana, it is known that the character was from one of Aesop's fables.
Neptune Vasilias was based on Neptune, the Roman god of the sea. However, in contrast to his origins, Neptune is scared of water, which is ironic.
