Zenos Yae Galvus

Zenos yae Galvus (Japanese:ゼノス・イェー・ガルヴァス (Zenosu Iē Garuvasu) is a Rank S Yo-kai of the Tough Tribe.

Biology
Zenos wears dark full plate armor and often appears behind a horned pale white mask. He incorporates some of Ala Mhigo's traditional outfit into his appearance, adorning his suit of armor with trial textile and a belt. Zenos is the second Garlean antagonist to go without his mask at times, the first being Nero tol Scaeva. He is a man in mid 20s with a youthful face, fair complexion and long golden hair. His weapon of choice is the katana. He carries three in a "sword revolver," prominent throughout promotional materials. The revolver has been compared in appearance to a golf bag used to carry golf clubs, and even has a kickstand for when it is not in use

Personality
Zenos is arrogant, selfish and callous. Having been raised as the heir apparent, he disregards the importance of human life. Drunk on power as the crown prince and viceroy of both Ala Mhigo and Doma, Zenos cares little for his job of governing the provinces.

Since Zenos never found challenge in battle, he treats his conquered subjects as prey to hunt and partakes in battles for the thrill of the kill. His purpose in war is to collect swords. Alphinaud admits Zenos is a peerless warrior and an accomplished general, the crushing of the Doman rebellion standing as proof of that. What Zenos loathes most is an opponent who does not provide enough "sport" in battle or cowards who flee.

Though Zenos views enemy and ally alike with contempt, he acknowledges the uses and strengths of his servants and allies. This includes Yotsuyu goe Brutus's hatred for her people to break the natives of Doma, Aulus mal Asina's scientific theory that would give Garleans the means to wield magicks, Fordola rem Lupis's desire to uplift her people to be accepted by the Garleans and to achieve the power to make all those who mocked her pay, and Asahi sas Brutus's zealous devotion to him. Nonetheless, despite most of them being loyal, they are expendable to Zenos.
