Ark appears to be an eidolon of Terran origins, guarding the Gulug Stone in Oeilvert, an ancient Terran archive, and a red moon features during its summoning. The pattern its lasers draw on the ground includes the triangular emblem of Terra that appears in many locations associated with the planet, and the glyph-like language that appears throughout Terran related artifacts. Ark is also the only eidolon not featured on the Eidolon Wall in Madain Sari.

SPECIAL ABILITIES (phase i)
Cruise Chaser (Ex)
Once below 50% hp (820), This Burst Mode lets Ark transform into a mech, performing better and new techniques. For a number of rounds equal to 1 + 1 round for every four HD, Ark gains +3 dodge AC, and changes a list of abilities down below. This limit break requires only a swift action to activate. Even after this wears off he keeps the mech transformation until the end of the fight.

Once every 1d3+1 rounds as a standard action, Ark shoots out one propeller in an arc hitting all enemies within the outside radius up to 60 feet. Once the radius is chosen (60-ft.-radius maximum) and if he hits (+50), Ark deals damage equal to triple his slam damage to all foes in the outside circle radius, 15-feet thick.
During Phase II, he shoots out two propellers instead of one.
During Cruise Chaser, increase his damage to quadruple his slam damage.

The rays may be fired at the same or different targets, but all rays must be aimed at targets within 30 feet of each other and fire simultaneously. Blue mages may learn this ability as a 3rd level spell (Knowledge: Planes DC 21).

During Cruise Chaser, add an additional 2d6 points of damage and converts half of the damage to lightning.
