Abaddon

Megami Tensei

Abaddon is featured throughout many installments of the Megami Tensei franchise and its spin-off's, where he is oftenly reffered to with the nickname the Destroyer.

His first appearance is in Shin Megami Tensei. There he appears with the angels' trumpets to herald the Doomsday. He uses fire, ice and venom breath in combat.

Shin Megami Tensei II

Abaddon appears as a demon under the control of the Center in Shin Megami Tensei II. He swallows the Valhalla district and everyone in it early on in the game.

After confronting Lucifer in Kether Castle, Aleph and Hiroko are swallowed by Abaddon and sent into the Abyss. While traversing Abaddon's innards they encounter the Madame, former ruler of the Valhalla district. She laments the fate of her people before passing away.

Parts of the Valhalla district can be accessed from within the Abyss, and the protagonists meet with Mekata, who had unfortunately been waiting in the area at the time. He explains the purpose of the Messiah project, as well as both Aleph and Hiroko's role in it. Mekata then gives Aleph the MAG Presser, a key item necessary for destroying Abaddon's core, before inevitably passing away as well.

When Aleph finally reaches the center of the Abyss, Abaddon taunts the protagonists, as his true form is stored in another dimension. Aleph uses the MAG presser to bring Abaddon's core into the Abyss and then slays the demon, dispersing the Abyss and returning to reality. He also admits that Michael had promised to return him to his angelic form, on the condition that he swallowed Valhalla, before perishing.

Castlevania

Abaddon also appears in several installments of the Castlevania franchise where he is frequently referred to as the Master of Locusts.

His first appearance is in Castlevania: Dawn of Sorrow, where he is the penultimate boss of the game. He looks like a hybrid between man and locust, wearing a maestro suit and using a conducting baton to summon and control locusts.

Abaddon returns in Castlevania: Portrait of Ruin, where he is an optional boss encountered in the Nest of Evil. He is exactly the same in appearance and gameplay as he was in Dawn of Sorrow however his appearance there is considered non-canonical.

Abaddon will be featured again in Castlevania: Lords of Shadow 2 very different than his earlier appearances in the Castlevania franchise. In this installment, Abaddon will look more like a traditional demon but with a carapace and mandibles for arms. He is a leader of Satan's Armies, sent to the mortal world, to destroy Dracula and everyone else who would stand against them.

Darksiders

Abaddon is an important character in Darksiders.

He was the leader of Hellguard, a Heavens' host dedicated into wiping the demons of Hell. As that he appeared as a warrior angel. During the Apocalypse, Abaddon led his Hellguard to Earth to fight against the demons but he was ambushed and was struck down by Straga, a powerful General of Hell's armies.

Although he was believed to be dead, Abaddon was spared by Lilith who offered him a choice to serve in Heaven or rule in Hell. Abaddon chose the latter and he was reborn as a powerful demon lord known only as the Destroyer.

Hellgate: London

In Hellgate: London, the Beast of Abbadon (sic) is a minor boss that makes an appearance in the mission 'A Luring'.

He is a located at the Tower of London and he is the source of a terrible atmospheric disturbance that prevents the Templars from utilizing their portals and extract one of their own there.

Thus the player's character is tasked by the Templars to seek out the Beast and slay it.

Guild Wars

Abaddon is the main antagonist in Guild Wars: Nightfall.

He is the fallen God of Water and Secrets and he has been worshiped by the ancient sea-faring nation of the Margonites.

In 1 BE (Before the Exodus), Abaddon brought magic to the races of Tyria, which resulted in devastating wars. When the gods sought to limit the use of the magic by rendering it into the five Bloodstones. That infuriated Abaddon who attacked the gods but he was defeated and banished in the Realm of Torment.

But Abaddon never rested, he plotted his return and sent out his minions to create cults to worship with the ultimate goal of returning to the world. He came close when his cultists attempted to enact Nightfall, an event able to bring back a forgotten god as as he. But his plans were thwarted when the Order of Sunspears and the Order of Whispers entered the Realm of Order to fight him and defeat him there.
