Magha has the ability to turn objects into fragile skeletons, imbuing them with the element the object had for enhanced strength. For example, if he turned a flame into a skeleton, it possesses a fiery exterior covered in flame.
Magha also has the ability to turn completely invisible due to his ghostly body, allowing him to disappear into thin air.
Magha was presumably the weakest Underlord, with his initial ability to control the dead with his body extremely vulnerable. When he was banished by Kareth Malvorr to Earth, his body disintegrated, allowing him to become one with the dead. Magha emerges as a formidable threat controlling a mass of skeletons when he is resurrected from the Eucalipse Jaws.
He establishes himself as a dangerous antagonist worthy of the protagonists' attention. Magha conducts strategic attacks specifically targeting Elias, simultaneously testing the limits of the young hero's power while advancing toward his true objective. His single-minded pursuit leads him to East Timor, where he initiates the critical resurrection ritual for the True Ajespan Kings. Just as Magha believes he has achieved victory, beginning the ritual to awaken his masters, he faces an ironic defeat as Elias cleverly exploits his spectral nature, causing him to overload with cosmic energy. In a twisted fulfillment of his purpose, even Magha's destruction serves his masters' return, as the energy released from his explosive demise completes the resurrection ritual he began.
