Aegaeon (Japanese: ワダツミ, Wadatsumi) is a Special Legendary Blade in Xenoblade Chronicles 2. He can grant tremendous power to his Driver, Emperor Niall, who eventually grants Mòrag Aegaeon's Core Crystal after deciding he is unfit to be a Driver. Aegaeon uses the water element, wields a Chroma Katana, and acts as a Tank in battle.

In Torna ~ The Golden Country, Aegaeon is a Blade who can grant tremendous power to his Driver Hugo and his allies.

Aegaeon was designed by Yūsuke Kozaki, who is best known as the character designer for Fire Emblem Awakening and Fire Emblem Fates.

Personality

Aegaeon is a quiet and steadfast Blade who acts as the emperor's shield and consul. He is reserved but swift to execute his Driver's will, and has acted in the interests of the royal family of Mor Ardain for at least 500 years.

Appearance

Aegaeon bears passing resemblance to a common blade, with black skin, white armor and blue energy lines across his body. Aegaeon has a pointed helmet, a white coat and boots, and blue tubes presumably of liquid from his head and knees.

Story

Like Brighid, Aegaeon is passed down from generation to generation of the Ardainian royal family. He also keeps a journal chronicling his past, although it is mentioned only in passing in the quest Farewell, Good Friend.

Aegis War

Aegaeon, Brighid and their driver, Hugo

During the Aegis War, Aegaeon was the Blade of Emperor Hugo. Hugo's brother was unable to become a Driver, and thus Hugo became the Driver of both Brighid and Aegaeon. Should Hugo fall in battle, the Special Inquisitor was to retrieve Aegaeon and Brighid's Core Crystals.

Aegaeon arrived at Torigoth alongside Hugo and the Special Inquisitor to end the battle between Brighid and Addam's crew. Aegaeon then suggested that the group head to the imperial flagship to discuss their next path forward, but Haze and Lora stayed behind in Torigoth Village. While on the ship, Aegaeon briefly left to investigate a loud noise from outside. He later reported that the returning soldiers had mentioned a mysterious group of mercenaries heading towards Torigoth, and Jin rushed back to Lora's aid. After the group dealt with Gort and his mercenaries, they all headed back onto the flagship. Hugo reported that Addam's militia was taken over by the Kingdom of Uraya, and Aegaeon confirmed the militia to be traveling to the Kingdom of Torna. Addam then asked Aegaeon to communicate to his militia to meet him in Aletta.

As the group arrived in Aletta, Aegaeon noted how Addam was far more popular than should be expected for someone fourth in line to the throne. He joined Addam in his fight against Malos alongside his Driver, Hugo. After Malos claimed to wait until the group met him at the Tornan Titan's core, Aegaeon wondered if Malos could be trusted on his statement. After Hugo sacrificed himself to shield Addam from the core's explosion, Aegaeon returned to his Core Crystal. Lora later gave his and Brighid's Cores back to the Special Inquisitor.

Emperor Niall

Aegaeon and his driver, Niall

500 years later, Aegaeon had become the Blade of Emperor Niall. He acts more as an advisor to the Emperor rather than his partner in combat, and is first seen reporting to Mòrag and Brighid on Jin's attack upon an Ardainian vessel carrying a large shipment of Core Crystals to Indol. He later attends the Ruler's Congress in Indol with Niall. As Giga Rosa is defeated and Bana attempts to use her self-destruct feature, Aegaeon protects the party by forming a protective shield around them. Niall, however, runs out of the shield trying to take the device from Bana, resulting in him being fatally injured. Aegaeon then returns to his Core Crystal, and Niall is resurrected with the help of Nia. After returning to Alba Cavanich, Niall gifts Mòrag with Aegaeon's Core Crystal declaring himself unfit to be a Driver. Aegaeon can only be re-awakened by Mòrag.

Aegaeon's Heart-to-heart, "At the Seat of Power", takes place in the Throne Room of Hardhaigh Palace between Aegaeon and Brighid. It is the only Blade Heart-to-heart to exclude that Blade's Driver. In it he and Brighid discuss Aegaeon's past as Emperor Niall's Blade and that Niall has forbidden Aegaeon from learning about this past. Aegaeon is ashamed of this and believes it due to his failure to protect Niall, but Brighid reassures him that the Emperor values him highly and that she looks forward to working with him as a future Emperor's Blade.

Due to his importance in the main plot, Aegaeon does not have a Blade Quest.

Haze	"Master Aegaeon is a… finely sculpted Blade, isn't he?"
Lora	"He's got a very estable core, doesn't he? He must have incredible balance. And that form!"
Aegaeon	"I would… appreciate it if you could stop staring, now. You're making me blush."

Lora	"How are you managing there, Hugo? Not too tiring for you?"
Hugo	"Hm? No, I'm quite alright. It will take more than this level of fighting to put me down."
Aegaeon	"Uh… Beg pardon, Lady Lora, but worrying about His Majesty's well-being is part of MY responsibilities."

Lora	"My hair has really been getting in the way whenever I fight. Time for the fringe to go."
Aegaeon	"A good idea. 'twould help bring out your beautiful eyes."
Lora	"Oh, you think so? Well, thanks, I suppose."

Lora	"I don't know how long it will take. But eventually, I want to be strong enough to protect all of you."
Aegaeon	"I feel the same, Lora. Let us strive toward this goal together."
Lora	"Thank you Aegaeon. I'm glad to have you with us."

Aegaeon	"Your swordsmanship is an inspiration to me, Jin. 'tis a marvel to behold."
Jin	"I simply removed all that was surplus."

Aegaeon	"You look tired, Haze. Here. Just don't tell anyone."
Haze	"Are those sweets? Oh Aegaeon, how can I ever repay you?"
Addam	"Aegaeon! You scallywag."

Aegaeon	"Such beauty… Were Haze but not a Blade, she could easily become His Majesty's consort."
Haze	"Uh? What was that you said, Master Aegaeon?"

Addam	"Aegaeon. If you don't mind my saying, aren't you being a little overprotective of Hugo?"
Aegaeon	"The bonds tying me to His Majesty are stronger than anything in this world. I could never leave his side, not for any reason, ever."
Mythra	"I think "overprotective" might be an understatement."

Mythra	"Aegaeon. Important question. Who do you think is stronger, me, or Brighid?"
Aegaeon	"Hm… You put so much stock in external displays of power, do you."
Mythra	"What do you mean? Strength is strength, right? Right?!"

Minoth	"Aegaeon, you and your teammates are great at teamwork."
Aegaeon	"Thank you, Master Minoth. You and your companions also moved as one."

Aegaeon	"Your Majesty..! You're so… modest."
Hugo	"Aegaeon… Are… Are those, tears?"

Aegaeon	"Your Majesty, I implore you not to overdo it."
Hugo	"Your advice is appreciated. But if I do not push my body, it will only grow weak."
Aegaeon	"But that is precisely why. If you suddenly start exerting yourself now, your unprepared joints may suffer under the stress."
Hugo	"I said I would push myself, Aegaeon, not try to… deadlift a Jagron."

Condition: After Lora becomes a knight of Torna
Aegaeon	"Minoth, did you see the way His Majesty prevailed in the last fight? Wasn't it quite… magnificent?"
Minoth	"Hm, yeah, I suppose it was."
Aegaeon	"Well, in that case…"
Minoth	"In that case why don't I make him the protagonist of one of my plays, yes? Sure thing. I'll consider it. At least."

Etymology

His name may be a reference to one of the Hecatoncheires, three Giants of the Greek mythology. In fact, if he's made the leader of a team in Merc Missions, the name of his group is the Hecatonics, which may be also be a reference to the Hecatoncheires themselves. His Japanese name may be a reference to Watatsumi (綿津見, わたつみ), more commonly known as Kaishin (海神, かいしん), a Shinto deity of water in the Japanese mythology. He sometimes referred to Poseidon or Neptune.

Trivia

• Aegaeon and Dromarch are the only Legendary Blades without a unique weapon class. Coincidentally, they are both water element blades with access to Ancient Wisdom and Water Mastery and are the only male Legendary Blades.
• Outside of New Game Plus, Aegaeon and Roc are the only Legendary Blades that can be sent away on Merc Missions and the only ones that can be freely disengaged from the party. They are also the only Legendary Blades that are obtained through bonding with Core Crystals. They are also the only Legendary Blades in Xenoblade Chronicles 2 to not appear in Xenoblade Chronicles 3: Future Redeemed or Super Smash Bros. Ultimate in any way. However, unlike Roc, Aegaeon appears in Pyra and Mythra's fighter reveal trailer for Super Smash Bros. Ultimate, appearing alongside Niall. They are also the only Legendary Blades to not receive any DLC Alternate Costumes.
• Both Nia and Zeke have voicelines for switching to Aegaeon in battle, despite not being able to engage him. Despite this, if one edits the Blade table and sets Aegaeon to be freely engageable on any driver, he works flawlessly, including his Level 4 special, in contrast to Dromarch, who will cause the game to softlock if anyone other than Nia or Rex uses Dark Maelstrom.
• Aegaeon is the only Legendary Blade in Xenoblade Chronicles 2 to not have a Nintendo Switch Online user profile icon element dedicated to him.
• Aegaeon's interaction with Godfrey is very likely in reference to Mobile Suit Gundam's legendary rivals Char Aznable and Amuro Ray, who are also voiced by Shūichi Ikeda and Tōru Furuya respectively.
