Aquinas, also known as Aquinas Halphas, is the twin brother of Anthony Halphas and a user of Celestial Titanic Magic.


Aquinas has Dark Brown hair and Dark Brown eyes. He is sort of pale, and is almost always seen wearing black cargo pants, black boots,a black muscle shirt,a silver belt, and a dark red blazer with a silver trim. On his belt, he wears a key ring with all his Gatekeys on them, similar to Lucy Heartfilia, but unlike his brother Anthony Halphas, who uses Requip to summon his keys.


Aquinas has a very sadistic and evil personality. He is very vain and believes his magic can surpass all other forms of Magic. He only trusts himself and will betray his friends in a hearbeat. He may not look it, but he is very intelligent and sneaky.


Aquinas was born to Lucas and Lorelai Halphas on October 3rd, X774. When he was a baby, while strolling around in the park with his parents and twin brother, a strange man kidnapped, him, and the only thing the parents saw was part of a guild mark. As Aquinas grew up, the Grimoire Heart Guild took care of him, teaching him the ways of magic. They knew he was a wizard, but they didn't know what kind of wizard he was.

When he was 10, They took him to a magic shop and forced the owner to let him try out all the different kinds of Magical Items they had. They ransacked the basement and found a key, hidden deep under ground. The Owner said it was a Titanic Key, and the owner explained that some Celestial Spirit Wizards could summon the Celestial Gods from Greek Mythology, but it was rare, and there was another kind of Celestial Spirit Wizard that could summon the Titans from Greek Mythology. The key was teal and had some deep blue engravings on it. It was the key of Oceanus, Titan of Water. They ransacked his entire store but they could find no more keys, so they took the Oceanus Key and left.

Aquinas became a full member of the guild at 15, and the grimoire heart guild treats him like a son, or a prodigy.

Magic and Abilities

-Celestial Titanic Magic- Aquinas practices Celestial titanic Magic, which allows him to summon Titans as Celestial Spirits. magical beings residing in the Celestial Spirit World, using the Keys of their respective Gates. When summoning a Spirit, the Keys are enveloped with a scarlet light. Once a contract has been made with a Spirit, such Spirit will be available for Aquinas to summon on certain days, in which it will fight on his side and perform several tasks for him.His Celestial Spirits have varying levels of power, with different ones being more suited for certain tasks than others.

  • Force Gate Closure - This kind of Gate Closure is more difficult than the Gate Closure that Lucy or Yukino posses, since Titans are more Powerful than Celestial Spirits. This ability is extremely difficult, and he is also shown using this after summoning several spirits at once.
  • Multiple SummonsSince Titans are more powerful than Celestial Spirits, it takes a great amount of power to summon multiple titans at a time. Aquinas has been shown summoning all his spirits at once, but this drained him of magic power, and he didn't regain even half of it in 3 days. He can summon two or more spirits, but it takes much less magic power than to summon all of them at once.
  • Unison Raid(合体魔法, ユニゾンレイド,Yunizon Reido): A spell which allows two Mages to unite their Magic into a single, combined and stronger attack. This is, apparently, a highly advanced form of Magic, with many priests having wasted their entire lives trying to achieve it, without success.
  • Titan War - Aquinas lays all his keys out in front of them and they hover, a soft, golden light and some wind coming out from underneath him. They all levitate into different positions, and the titans of the keys he is using appear, and the keys and the titans fly at the target at high speeds, hitting them with speed and power.

Expert Strategist - Despite the fact that pretty much no one but the Guild Master and a few members of the guild were very intelligent, Aquinas is a master strategist and is basically the reason that his Guild is at it's standing in Fiore.

Expert in Hand to Hand Combat - The members of the Grimoire Heart rely on brute strength, so Aquinas is very physically fit and pretty much an expert in Hand to Hand Combat.

Immense Magical Power - Despite the fact that Aquinas didn't regain all his magic power until a week after he summoned all his Titans at once, he still has an immense amount of magic power.
