Appearances Armored Core Last Raven

Principal (プリンシパル Purinshiparu) is a Raven who first appeared in Armored Core: Nexus. She worked for Alliance in Armored Core: Last Raven. She is ranked 10th in the Armored Core: Nexus Arena


Principal is the only female Raven in Alliance's Tactical Unit forces. She's a talented pilot, but lacks actual combat experience. It is speculated the she chose Alliance believing they could offer her protection. She is encountered in the mission "Destroy AC Sundial."

AC Sundial (US)/Sundial Feather (JP)[]

Principal has 2 versions of her AC Sundial known in Japan as Sundial Feather (サンダイルフェザー Sandairu Fezā). The first one appearing in Nexus, is a hover-legged craft equipped with the Centaur dual vertical missiles, inside decoys, a sniper rifle, an AST rifle & relay missile extensions. Her unit is also equipped with an overboost core.

Last Raven AC description: Hover-leg AC design built with an emphasis on mobility. While equipped with multiple weapons, the vertical missiles are this unit's hard hitters.

Principal’s AC in Last Raven has changed a bit. It retains the OB core, the CENTAUR vertical missiles & extension missiles, while its main weapons are changed to a machine gun and a two-shot sniper rifle. She also changes the inside decoys for ECM makers.



Principal can only be fought as an Arena opponent. But even then, she's far from unbeatable. Despite having OP-INTENSIFY, she is still a pushover. Her vertical missiles can be easily averted with decoys or any other kind of missile defense, and she doesn't have much firepower to save herself. Being a hover AC, she does have limited durability, so it's easy to blow her apart with heavy firepower and hard-hitting weapons.

Last Raven[]

Her Vertical Missiles are the biggest threat but staying agile will keep them at bay. She is very light and doesn't really have an AMS system so missiles are extremely viable. She does Overboost quite a bit but waiting to launch after she stopped Overboosting will almost garantee hits. She is very fragile and like most hovers, her legs can easily be broken by weapon fire. This leaves her vulnerable and she really doesn't have that much good firepower.

Being a tank and just pounding her works well to. The missiles are a bit of a hazard but heavy cannons will frequently break her legs easily causing her to die, quickly.
