Unfriend (Slash Command)
From City of Heroes: Rebirth - Wiki
Slash Command
- /unfriend name
Removes a player from your server friends list.
Notes
- You can use /unfriend only on a character name.
- This option can be used whether or not the target character is online.
- This option cannot be used on cross-faction characters (hero characters cannot invite villain characters, and vice-versa, to be server friends).
