Neutral
From Legacy Roblox Wiki
This Bool value sets whether the SpawnLocation can be spawned at by all teams or just the teamColor it is set to. If the box is ticked the Spawn can be used by all teams. If not it can only be used by the TeamColor the Spawn is set to.
Neutral is also a property in Player, which denotes whether or not a player is on a team, or not on any team.
