I intended the pinks to be more plum but whatever. Mannimarco would make quite the OP Manakete, able to wield both Dragonstones and Staves.

Mannimarco is from the bad future of Fire Emblem Awakening, a worshiper of Grima. He defeated Vanus, another Manakete who was his former partner, but just as he did, Grima Robin approached him, confronting him for his treachery. Mannimarco had in fact planned to overthrow Grima. Grima Robin attacked, but Vanus used his last bit of strength to stall him long enough for Mannimarco to run, still unwilling to see Mannimarco get hurt even after all the time they spent as enemies.

Mannimarco fled into the Outrealms, and then came through the Dragon's Gate into Nohr, where he met Corrin, who fought off the Risen that had given pursuit.

Mannimarco can S-Rank with Flora or either gender of Corrin. In Revelation, he can S-rank with Vanus, who is not the Vanus from his own timeline, but rather from the GOOD ending of the Awakening timeline. If he marries he will have a daughter named Morianya (who will be adopted if he marries a man). Kana however will not be produced if Mannimarco marries male Corrin, due to conflicts with Kana's personal storyline.

Mannimarco's reclass is Dark Mage. He can also be a Witch despite being male (and yes he DOES wear the dress.) Overall, he is very similar to Vanus, but has higher Defense and Skill than him, and lower Resistance and Speed.
