Purgstall, in spite of being one of the twelve most powerful beings in the world, was considered timid, and disliked both violence and confrontation. He genuinely cared for the people that he was entrusted to governor over, and stood up to the Gigantic Guyver when he believed they were in danger; even though he knew Imakarum Mirabilis, a much more powerful Zoalord than himself, had been nearly killed by the Gigantic Dark.
Purgstall was one of the most loyal followers of Archanfel and placed his goal above all else, including his own ambitions. Purgstall was also loyal to his mentor Dr. Barcas and his close friend Sin. He believed that his fellow peers and council members were all close allies and friends of his, and he treated them all as such. Purgstall went above and beyond to treat the people around him with care and fairness, something noted by his fellow peers, who either appreciated his unique sense of treatment to "lesser beings" or disagreed with it.
Despite the fact that he disliked fighting, he desired to end both any resistance to Chronos's control over the world and infighting from his peers immediately whenever he could, which ultimately led to his demise.
He mentioned that Dr. Barcas had chosen him in Vienna, 215 years before the present. This, and his name, strongly imply that he was Austrian (Technically, a Bohemian and citizen of the Holy Roman Empire). He apparently was a citizen of Purgstall an der Erlauf, an ancient fortified market town in what is now north-east Austria. In spite of his name, he is apparently not a nobleman, because at the time Purgstall was ruled by the Schaffgotsch family. On the other hand, there was a count of Purgstall, namely Godfrey Wenceslaus, who was such until at least 1811 when he died.
Powers & Abilities:
Super Strength: As a Zoalord, Friedrich von Purgstall is far more powerful than any Zoanoid or Hyper Zoanoid, and likely possesses strength comparable to that of a regular guyver while he is in human form and much higher while in his battle form. Although all Zoaloads are physically stronger while they're transformed, it was stated that Friedrich was not a melee fighter and as such it can be assumed that even when transformed, his strength is not as high as that of more combat oriented Zoalords, such as Imakarum Mirabilis.
Super speed: He flew from his base at “Cloud Gate” to the battle between Guyver Gigantic and Neo Zx-Tole in a matter of seconds. His speed was high enough to be able to keep up with Guyver Gigantic.
Super durability: Along with the heightened durability he has while transformed by virtue of being a Zoalord, his unique powers allow him to absorb electricity and heat, such as when he blocked Guyver Gigantic's regular head lasers with his forearm and how he was unaffected by the ambient heat created by a lava pool. Furthermore, as he was unaffected by his own incredibly powerful lightning bolt, it can be surmised that he is immune to damage from electricity.
Electrokinesis: Friedrich von Purgstall possesses the ability to generate and control vast amounts of electrical power. Even while in human form, he was able to fire a powerful lightning bolt from his hand that caused great damage to the relic. When he transforms in an open area, thunderclouds immediately form in the sky above him and over a great span. From these clouds, he can call down massive lightning bolts that are easily capable of obliterating sky scrapers and melting the ground, leaving large pools of lava behind. While in battle form, Purgstall has a Zoa crystal embedded in the center of his chest that is similar to the one in his forehead. He can fire concentrated lightning from this crystal and it seems to be his only defense at melee range. As any other Zoalord, he can also fire a very powerful laser from the Zoa crystal in his forhead. Friedrich, as mentioned, is not a melee fighter, but is more fitted to ranged combat; it was noted by Sho Fukamachi that as long as Sho stayed at a long range from Friedrich, he would remain at a disadvantage as the Zoalord's attacks were highly effective. As he had command over electricity, it is entirely possible that Friedrich von Purgstall possessed other forms of electromagnetic powers, though none were seen in his fight with Guyver Gigantic.
Forcefield: Friedrich can create force shields, which is a base ability for a Zoalord. However, when transformed, his barriers seem to seethe with electricity powerful enough to burn the Gigantic's hands when touched.
Telepathy: Like all the Zoalords, Purgstall possessed psychic control over all Zoanoids created by Chronos. His range and power level is unknown however, though as Hamilcar Barcas is stated to possess the most powerful psychic abilities among the Zoalords (after Archanfel), it can be safely assumed that Friedrich's telepathic powers are inferior to the good doctor's. This telepathy cannot be used on humans and Lost Numbers.
