Caster Magic User: Being the Master of the Fairy Tail guild and a member of Ten Wizard Saints, Makarov is an immensely powerful individual despite his old age. He possessed such enormous magical power that Angel, one of the Oración Seis able to take a guild by themselves, would have been deeply troubled if another wizard saint, Jura Nekis, was of the same power. He was also said to be among the most powerful Ten Wizard Saints, given his ability to beat Jose Porla, another Wizard Saint.
Jura himself admitted that he was far weaker (comparing the difference between them to the distance between heaven and earth) than Makarov even though he was still able to easily defeat Brain, the leader of the Oración Seis.[14] Another example would be that just his magical presence, when enraged, was enough to cause objects around him to be destroyed, the other mage who was shown to have this ability is Gildarts who used his magical aura to overwhelm Natsu. It must be noted that Makarov is not what he once was, and the amazing power he has displayed is as his now- it unknown how much more powerful he was in his prime. As further testament to his power, even the Seven Kin of Purgatory were taken aback by his Titan magic.
Another spell which noted Makarov's extreme magical power is his Fairy Law. Said to be possible the most powerful single mage spell yet seen, Fairy Law is considered super-powerful that it's one of the rare legendary spells. The spell is so powerful that it defeated Jose Porla, the Phantom Lord's guild master and a fellow Wizard Saint, in a single blow.

Elemental Magic Specialist: Makarov also has various other unnamed magics asides Titan, such as a piercing lightning attack and a powerful shock wave-like attack. Also, according to his guild card, he has knowledge of several different elemental spells like earth, water, fire, wind and light.
Master Sensor: Makarov is able to sense magical presences very well. Knowing for example that Natsu, who had presumably been transformed into a lizard, was actually Macao when all the other members had been duped.
