Skull Squadron (スカル
Skull Squadron was a special unit led by Unification Wars veteran Roy Focker, named as such due to the skull marking usually emblazoned on his personal units. His first sortie as Skull Leader was in 2008, training rookie pilots with the newly rolled out VF-0 Phoenix and later facing off against Anti-U.N. Forces, among them his former instructor, D.D.Ivanov.
His call sign and status as Skull Leader remained even after being assigned to the SDF-1 Macross. Roy's earlier subordinates were not clearly identified, but he later takes former stunt pilot junior Hikaru Ichijyo under his wing after the latter enlists as a military pilot. Hikaru was eventually promoted and became the leader of the Vermillion Squadron.
After Roy's death, the Vermilion Squadron assumed the mantle of the Skull Squadron. Hikaru inherited the Skull Leader title as well as his senior's VF-1S Valkyrie.
In an alternate universe, Roy was still leader of the Skull Squadron while his subordinates were Hikaru, Max and Kakizaki. Max became Skull Leader after Roy's passing, but was taken over by Hikaru when Max became MIA following his duel with Milia Fallyna Jenius.
