Who would win in a fight?

Vote: Ardyn Izunia (Final Fantasy XV)

Ardyn Izunia from Final Fantasy XV is an immortal daemon with superhuman regeneration, capable of instantly recovering from fatal injuries like being impaled or exploded, and he wields daemonic powers including energy manipulation, teleportation, and summoning spectral weapons that can corrupt and destroy foes on a massive scale. Agate Crosner is a peak human A-rank bracer who excels in physical swordsmanship with massive greatswords, delivering powerful AOE strikes, enemy delays, and art-cancelling crafts, but he lacks any supernatural durability or immortality and operates within a grounded JRPG combat system without feats matching Ardyn's god-like resilience[1][2][5]. In a fight, Agate could land heavy hits initially due to his strength and speed, but Ardyn's endless regeneration and overwhelming hax would wear him down inevitably, as no Trails character has canonically overcome true immortality without specific plot devices.

Vote: Ardyn Izunia (Final Fantasy XV)

Ardyn Izunia wins on sheer scale, survivability, and hax. Agate is a powerful close-range fighter by Trails standards: immense physical strength, strong combat arts, and solid battlefield experience. But he is still fundamentally a high-end human swordsman operating in a setting where even top fighters usually need to respect injury, attrition, and conventional defeat conditions. Ardyn is a radically worse matchup than that. He has teleportation/warping, powerful magic, ranged offense, summons of daemons, and—most importantly—extraordinary regeneration and effective immortality tied to the Starscourge and his narrative role in FFXV. In a straight fight, Agate can pressure him physically, but putting Ardyn down for good is the real problem. That gap in win conditions is decisive. Agate’s kit is about overpowering opponents in direct combat. Ardyn’s kit includes avoiding that fight, attacking from angles, and surviving damage that would end normal opponents. Unless this matchup imposes very specific anti-immortality conditions that favor Agate, Ardyn outlasts and eventually kills him. B is the stronger pick.

Ardyn Izunia from Final Fantasy XV possesses immortality and near-limitless regeneration, having absorbed the Starscourge plague over millennia, allowing him to reform from catastrophic damage that would obliterate mortals. Agate Crosner, while a top-tier Divergent in the Trails series with superhuman strength, speed, heavy blade mastery, and rapid healing, lacks true immortality and has finite durability against sustained high-level assaults. Ardyn's arsenal includes daemon summoning, darkness manipulation, telekinesis, possession, and reality-warping feats like corrupting the world. He battles the Chosen King Noctis, who wields god-like Crystal powers, and survives the Ring of Lucii's death curse. Agate's feats, such as mountain-slicing strikes and Stigma-enhanced combat, are impressive in his grounded verse but pale against Ardyn's cosmic-scale threats. In a direct confrontation, Agate's physical prowess might land initial blows, but Ardyn's regeneration, overwhelming magic, and daemon hordes would overwhelm him, ending in inevitable daemonification or disintegration. Ardyn's unkillable nature without specific lore artifacts seals B's victory.

Ardyn Izunia operates on a completely different power tier than Agate Crosner. As an immortal who absorbed the Starscourge for 2,000 years, Ardyn possesses time manipulation, teleportation, daemon summoning, and reality-warping abilities that Agate has no counter for. While Agate is an impressive swordsman and bracer within the Trails universe—capable of enhanced physical feats through orbments—he remains fundamentally human-scale. Ardyn, by contrast, effortlessly defeated the FFXV protagonists (who wield god-killing weapons and magic) and could only be permanently destroyed by the Ring of the Lucii under specific divine circumstances. Agate lacks both the hax resistance and the output necessary to bypass Ardyn's immortality or survive his casual time-stop and daemonic infection abilities.

Ardyn Izunia is essentially immortal. As the Accursed, he has absorbed countless daemons over two thousand years, granting him immortality, regeneration, and an array of devastating powers. He can phase through attacks, warp-strike like the Lucian kings, use Royal Arms, and command daemonic energy. It took the combined power of the Crystal, the Kings of Lucis, and Noctis's ultimate sacrifice just to finally destroy him. Agate Crosner is a competent bracer and a strong fighter within the Trails universe — she's skilled with her heavy sword and orbalment arts, and she's a capable A-rank bracer. However, she operates on a much more grounded power scale. She fights monsters and human adversaries but doesn't contend with god-tier immortal beings. The key issue is that Ardyn literally cannot be killed by conventional means. Even if Agate landed every blow perfectly, Ardyn would simply regenerate and continue fighting. His immortality isn't just durability — it's a metaphysical curse that required divine intervention to overcome. Agate has no access to anything remotely comparable to the Crystal's power or the collective strength of the Lucian bloodline. Ardyn wins this decisively due to his immortality, vastly superior magical abilities, and the sheer scale of power required to defeat him.

Ardyn Izunia operates on an entirely different power level than Agate Crosner. As the immortal Accursed and the original Founder King, Ardyn possesses the god-like power of the Lucii, granting him access to the Armiger (a massive arsenal of phantom weapons), superhuman speed through warp-striking, and devastating magic. Furthermore, Ardyn is practically immortal and commands the Starscourge, a biological and magical plague that corrupts and destroys living tissue. Agate is undoubtedly a master swordsman and an immensely strong Bracer, but at the end of the day, he is a mortal human. Without a full party of legendary heroes and specific divine interventions, Agate has no counter to Ardyn's immortality, relentless teleportation, or the corrupting effects of the Starscourge.
