Name: Lucina
Age: 22
Gender: Female
Appearance:

Canon, AU, or OC?: Canon
Universe of Origin: Fire Emblem
Personality: Lucina is a strong-willed young woman and quite stoic in her personality. She has a drive to change the bad future from which she came for the sake of the entire world; like Atlas and the sky, she carries the burden of the Fell Dragon and the new Ylissean guard on her shoulders. Lucina is determined and stern, yet has a kinder side; she also has a strong sense of justice and believes that it's her job to prevent the disasters of her time from ever happening.

However, as a result of the prolonged trauma she experienced in her timeline, Lucina may revert to a childlike fixation, especially in the company of those who resemble her family. Also as a result of this trauma, she has an extreme aversion to death of any kind, including deaths for a higher or more noble cause. She prefers to prevent death from occurring. In addition, Lucina, behind her outer layer of stoicism, has somewhat-severe emotional damage due to the loss of her father Chrom to one who was very close to him.

Another thing to note: she doesn't get jokes the first time.
Abilities/Weapons: Lucina is a skilled swordswoman, and primarily uses her inherited blade the [Parallel] Falchion, which is well-balanced and suited for her build, explaining why its efficacy is much more acute than Chrom's counterpart. The Falchion has the unique ability to restore Lucina's vitality and slowly heal her wounds.

In addition to her blade, Lucina has the skill Aether, which halves her enemy's defenses and restores her vitality with her sword strike. Like Ike's Aether in Super Smash Bros., Lucina will leap into the air and bring her blade down upon her target.

Lucina's fighting style is similar to the Hero-king Marth's.
Backstory: Princess Lucina is Chrom's adult daughter from a dystopian future in which the fell dragon Grima had successfully awakened and ravaged the continent of Ylisse. Sent by the divine dragon Naga to the past through the Outrealm Gate, Lucina takes on the massive responsibility of altering the course of history for the better of the world, taking on the persona of Marth via a mask that obscured her gender (in part thanks to her androgynous build). Lucina, as Marth, operated hidden from her father Chrom's army, acting upon her knowledge of the future in order to prevent the events that would lead to the rise of Grima from happening.

However, during the attempted assassination on the exalt Emmeryn, Lucina's mask is destroyed and her gender revealed to Chrom. Lucina partners with the Shepherds to drive off the assassination, and believes that the Exalt has been saved. Another attempt on Emmeryn's life, this time as a form of execution by Plegia's Mad King, Gangrel, succeeded(?) and Lucina, in horror, realized that the events of her desperate time were back on course.

During the events of the Valmese conquest, during a trip through the Outrealm Gate, Lucina became separated from the Shepherds due to a temporal/spacial anomaly caused by Grima's attempt to follow her and kill her. Lucina stumbled into the multiverse, unsure of where she was...
Faction: Unaligned for now.

Name: Grigori Rasputin
Age: Undead
Gender: Male
Appearance:

Canon, AU, or OC?: Canon
Universe of Origin: Anastasia
Personality: Rasputin, since becoming a lich, has remained dead-set on completing the curse he laid upon the Tsar's family for vengeance. He is a wicked man, who shows no remorse for killing off the entire Romanov family except for Anastasia (only because she escaped his grasp).
Abilities/Weapons: Rasputin has many, many green demonic minions from which he can summon from his reliquary--the powers he gained from selling his soul to the Devil. These minions do his work and attack for him; in addition to that, Rasputin has access to powerful black magic as well.

This isn't an ability, per se, but Rasputin, as a rotting lich, does tend to fall apart. The pieces do come back together due to the unholy magic that Rasputin has control over.

So long as his glass reliquary remains intact, Rasputin will remain alive, and able to carry out his revenge.
Backstory: Grigori Rasputin, or the Mad Monk, in an alternate version of early-20th-century Russia, was banished for treason and in anger, sought revenge upon the Romanov family. Selling his soul to the devil, Grigori gains the power to curse the Romanovs and kill every last one with black magic. However, he drowns after chasing the young Anastasia across a frozen river, losing his reliquary to the current, unable to die until he completes the curse.

Thanks to his albino bat minion Bartok, Rasputin, 10 years later, has his reliquary back in his hands and is bent on killing Anastasia and fulfilling the last part of his vengeance upon the Russian royal family. However, upon returning from Limbo, Rasputin found himself in the multiverse. Cursing his fate, howling, he vowed to use any means possible to return to Russia and complete his revenge, once and for all.
Faction: Shadow Eternity

Though he does not know it, Pilcrow was a combat robot sent to the floating island to steal the Demon Crown. However, shortly after his arrival, he was attacked by a witch and teleported into a massive labyrinth in the island's core. Here he wandered until he was almost destroyed by the labyrinth's fierce inhabitants, but was found and repaired by an engineer robot. As a result of his near-death, he lost all his memories, and continued to explore the labyrinth, eventually coming across the island's core. There, he found a woman who was apparently drowned, and took her machine gun before continuing his exploration. Eventually he came across an active teleporter that led to a massive farm full of rabbit-like monsters. In there, he found a rocket and the corpse of a male soldier that looked a lot like him, who had a handgun, flamethrower, sword, and an air tank, which he took. Riding the rocket up, he was able to reach the island's surface. There he found a helicopter surrounded by the corpses of people in labcoats. In his attempts to start the helicopter, he pressed a button that teleported the helicopter and himself off the island to a completely different, unknown location. Pilcrow now travels the multiverse in search of his memories, or some purpose to his existence.
