When activated, this Magic allows the user to enlarge their body to gigantic proportions, even to the size of the gargantuan Tenrou Island itself as well as the Dragons. In addition, it can also be employed on selective parts of the user's body, elongating them and making it look like the user possesses elastic properties of sort, coming in as a very versatile Magic. Titan’s effects can also be transferred to other people aside from the user, as shown when Makarov could use it to grow Reedus Jonah’s chest to the latter’s request, in order for his Pict Magic to work better. When the user employs their complete Titan form, their muscles bulge in size, with prominent veins becoming visible (though, when Makarov first employed it, he instead gained a slender figure).
- Immense Strength: As evident of their gargantuan size and increase in muscle mass, the physical prowess of Titan users is enhanced exponentially while in this state. Makarov, while using this Magic, was able to partially destroy a large airship with a single punch, subsequently damaging it further by lifting a gigantic wave with a single kick. Makarov was also able to stand his ground against Acnologia with this Magic.
- Immense Durability: The users' physical endurance is immensely increased while in this gigantic form. Makarov was able to take the blast from Grimoire Heart’s Jupiter cannon head-on with only a moderate burn on his large arm  and survive Acnologia's melee attacks.
- In Greek Mythology, Titans were huge, immortal beings of incredible strength and stamina and were also the first pantheon of Greek gods and goddesses.
