Proton Acnologia
Proton Acnologia
Voiced by: Jun'ichi Suwabe (Japanese), Bill Jenkins (English)
The original Acnologia and guardian dragon of Montes Secreta, where the current Acnologia once lived as his personal physician back when he was still human. However, he betrayed the humans of the village after being attacked by Dragon Slayers, leading to his doctor's fateful decision to enact bloody vengeance against all of dragon-kind.
- All There in the Script: He's only known as Acnologia in dialog. His full name, "Proton Acnologia", is revealed in closed captioning and the Funimation dub's credits.
- Beard of Evil: He's an old, bearded dragon who turns against humans after suffering horribly at the hands of Dragon Slayers.
- Broken Pedestal: He ended up becoming this to the current Acnologia after he went crazy and slaughtered the humans he had once protected. The pedestal was broken so hard, in fact, that he took it out on every other dragon in existence.
- Create Your Own Villain: His actions ultimately lead to the rise of the current Acnologia, who destroyed most of dragon-kind in retaliation for his actions.
- Face–Heel Turn: He was the guardian of a secret village in Ishgal where humans and dragons lived in harmony. Unfortunately, the horrific injuries he sustained from Dragon Slayers drove him to turn against mankind and burn the village to the ground.
- Facial Horror: He is shown having lost entire chunks of flesh, including nearly half of his face, from the injuries he sustained from Dragon Slayers. Unlike the mostly Bloodless Carnage of the anime, the gory details are shown in full for a few moments.
- Genocide Backfire: After discovering the terrifying power that humans are capable of with Dragon Slayer magic, this Acnologia leads a purge of all humans in his village. Unfortunately, one of the humans that escapes ultimately takes up his name and becomes the one dragon responsible for wiping the race to virtual extinction.
- A God I Am Not: The humans living in his village saw him as their divine guardian. According to the then-to-be Acnologia, this dragon had conflicting opinions on that.
- Killed Offscreen: Viewers are not treated to the sight of the current Acnologia taking his revenge on him, jumping from his declaration of revenge to him mopping up every other dragon he can find.
- Legacy Character: He is chronologically the first to be called Acnologia, with the second and current Acnologia taking on his name.
- Light Is Good: Subverted. He has light-gray colored scales and a protective instinct towards the humans of Montes Secreta, leading them to deem him as their divine protector...until the existence of Dragon Slayer magic ultimately drives him to become the exact opposite of this trope.
- My Species Doth Protest Too Much: Subverted. Like most dragons in Ishgal, this dragon initially can't bear the thought of dragons killing and eating humans in the west, but once he discovers what humans are truly capable of with Dragon Slayer Magic, he wastes no time destroying the very humans he swore to protect.
- Posthumous Character: He's long since fallen victim to the dragon purge 400 years in the past.
- Predecessor Villain: He is the dragon who single-handedly led the current Acnologia—the ultimate villain of the entire series—to deem dragon-kind as an inherently evil race and eventually abandon his love for humans as well.
- Stronger with Age: He appears to be rather old and feeble for a dragon, but he's a dragon nonetheless, making him one of the most powerful creatures to walk the face of Earth-land.
- Walking Spoiler: The mere knowledge of his existence sheds light on the Acnologia that most of those familiar with the series would know.
- We Used to Be Friends: He used to be on cordial terms with the doctor who would become the current Acnologia, giving him words of encouragement when he doubted his own ability to protect dragons against the power of Dragon Slayer magic. Unfortunately, after being subjected to that very magic, Proton Acnologia snapped and destroyed everything the doctor held dear, including his compassion for dragons.
