Black Waltzes also sport a set of blue feathered wings. The individual appearance of the Black Waltzes varies slightly, and each model is more elegant than the previous.
Black Waltzes also differ from Black Mages in that they have been given free will from their creators. They do not consider themselves to be part of the Black Mage army, but rather that they are separate and superior to the "soulless dolls." The Waltzes were assigned to follow orders and answer directly to Queen Brahne herself, and were dispatched one by one to capture Princess Garnet immediately after her flight/kidnapping with the additional instruction not to harm Princess Garnet herself. In battle, they will not attack Princess Garnet, and when she is the last remaining character they will cast
Sleep on her to capture her. Since their retrieval of Princess Garnet is their only mission revealed in the game and each one is destroyed during this mission, it is unknown what capacity they served the Queen beyond this function.

Zora sends the Delilas Siblings to attack the Ra-Seru heroes, but they fail and the heroes reach the castle with the help of the Soren. After Zora is defeated, Songi appears and disables her mist generator. He goads Zora, telling her that she meant nothing to Cort, and then kills her. As he leaves, he tells the heroes that they have only six minutes until Zora's Floating Castle plummets from the sky.
Songi then disappears for some time, reappearing only when the Juggernaut is about to engulf Rim Elm. Songi announces its arrival to the Ra-Seru heroes, and then jumps through a portal to Seru-Kai, where he attempts to drain the power of the Great Genesis Tree in Noaru Valley. Vahn, Noa, and Gala pursue him by using a portal at Uru Mais, and discover him in the act. He is forced to stop in order to do battle with the heroes, but he taunts them prior to attacking, claiming to be Tieg himself. During this battle, Songi takes the form of a gargantuan creature, and may use "Chaos Flare" and "Genocidal Cannon". Following his defeat, his Seru separates from him, exposing him to the power of Seru-Kai, which causes him to turn into stone.
Lavos
is Chrono Trigger's primary villain, and is an alien parasite that crash landed in the year 65,000,000 B.C. and was named by Ayla ("La" meaning "fire" and "Vos" "big" in an ancient language). Lavos' true name (if it even had one) is unknown. Lavos came to Earth with the intention of draining its energy so that it could produce genetically enhanced spawn, which would then continue the cycle on other planets. In the North American version of the game, it is claimed once in the series that Lavos directly influenced all technology and life on the planet, evolving the planet's life forms to cultivate it, and make itself stronger. However, the line is absent in the Japanese version.Despite it originally just being in translation though in Chrono Cross it appears this actually is the case as a large portion of the game involves many layers of time line event controller which all end at Lavos. In the original timeline, Lavos slept for millions of years, gaining power until 1999 A.D., when he emerged and put the world into an apocalyptic state. However, because of the interference of many of the characters, he was summoned at two other points in time—12000 B.C. and 600 A.D. While traveling in 2300 A.D., Crono, Marle, and Lucca see a video of the Day of Lavos which occurred in 1999 A.D., and decide to prevent it somehow. Magus is also after Lavos for destroying his home era of 12000 B.C.Lavos has three different forms. The first form is the outer shell. The second form consists of a large humanoid form with two arms. The third and final form is Lavos Core, consisting of three parts: a humanoid center, and two 'bits'.While the natural "dreamstone" is a substance responsible for the first evolution of human beings from animal apes to sentient creatures, it is revealed in Chrono Cross that Lavos is responsible for the creation and advancement of the actual modern human species. Upon impact, a splinter of Lavos's shell broke off. This becomes the focal point of Chrono Cross, the Frozen Flame. Lavos is also the final boss in Chrono Cross, except in the form of the Devourer of Time, the result of the defeated Lavos assimilating Schala in the darkness beyond time. I don't know who lavos is cause i never played the chrono seires EVER but i got my sources and links heheh.... Exdeath
is a powerful warlock, would-be ruler of a parallel world, and the antagonist in Final Fantasy V. Exdeath also makes a cameo as the Viera Totema Exodus in Final Fantasy Tactics Advance and as a summon Esper in Final Fantasy XII.Exdeath was originally a single tree deep in the Moore Forest, which the people of that world had used to seal countless demons and evil spirits in for centuries, until about 30 years ago, when the tree developed its own sentience from all the evil it had contained and assumed a human-like form. After being defeated by the four Dawn Warriors (Galuf, Xezat, Dorgann, and Kelger), Exdeath was imprisoned within the first world, sealed by the power of the crystals, some 30 years before the events in the game. At this time, he shatters the four crystals one by one, just before the heroes are able to save them. After the fourth crystal is destroyed, Exdeath is released and returns to the world of his origin and where Galuf comes from.
Here, he returns to his castle.Gus , Lenna, and Faris are captured shortly after warping to his world. They are used as hostages to keep Galuf and his army from attacking. It is protected by a powerful barrier that is generated by four towers surrounding the castle; Exdeath activates the barrier while the four are on the Big Bridge, which catapults them to Gloceana and would have killed any of Galuf's soldiers on the bridge. To attack the castle and defeat Exdeath, the heroes must destroy one of the towers to disable the barrier. In Exdeath's world, the four crystals are contained in the Elder Tree in Moore Forest. Exdeath destroys these crystals, because they are holding the two worlds apart, as they were once a single world, but were separated. He kills Galuf, who tries to defend the crystals and his friends. By doing so, the two worlds recombine, and Exdeath gains access to the power that was sealed by the separation of the worlds, the Void
He utilizes this power to great destruction, effectively annihilating Tycoon Castle, Gus's hometown, and other locations. When the Warriors of Dawn challenged him, he attempted to use the Void on them. However, in the ensuring fight, in which Exdeath reveals his true form as a tree, Exdeath became a victim of his own instrument. He emerged as
Neo Exdeath, a chaotic vessel of the Void itself composed of the various evils that gave Exdeath life protruding from its body. Now nothing more than a host to the very power he sought, Neo Exdeath desired to turn all to nothingness, presumably so that it, too, could disappear. But the warriors destroyed Neo Exdeath, recreating the four crystals that restored all the damage caused by the Void.

Though Firion, Maria, and Guy wish to search for Leon, they soon begin to focus more on their duties as members of the Wild Rose rebellion. Soon enough, however, Maria recognizes the voice of the Emperor's newly appointed right-hand man, the Dark Knight as that of her brother. After Firion, Maria, Guy, and Ricard kill the Emperor, the Dark Knight reveals himself to be Leon and declares himself the new Emperor of Palamecia. Maria believes Leon is under a spell but the party finds out Leon simply desires power over friendship and confronts them. Unhappy with Leon's self-promotion, the true Emperor returns from Hell to unleash his anger on Leon and destroy the world.

Only through the intervention of Elena and Millenia does Ryudo manage to overcome the Horns and escape Melfice's fate.

Gabranth , born Noah fon Ronsenburg is the Judge Magister of the 9th Bureau. The 9th Bureau, led by Gabranth, is primarily concerned with the gathering and dissemination of information. As a result, many of the bureau’s activities are shrouded in secrecy. Gabranth, and his power, are respected by the other Judge Magisters, and Emperor Gramis himself places great faith in this younger Judge. He is also Basch's twin brother, the man truly responsible for the deaths of Reks and King Raminas. Unlike Basch, he wholeheartedly supports Archadia. After the fall of Landis, Basch left for another country leaving Noah and their mother, who was suffering from an illness at the time, behind. But Noah couldn't leave their mother in her condition, and moved with her to her home country of Archadia. In an effort to distance himself from Landis, he took on his mother's surname, Gabranth. Noticed by Emperor Gramis, Gabranth joins the Archadian Judges with the Emperor's backing and rises to become a Judge Magister. Eventually his mother succumbs to her illness and dies, and Gabranth's feelings towards his brother finally change to hatred for what he sees as him abandoning his homeland and family. At the Emperor's behest, he acted as an informant on the dealings of Lord Vayne and became Larsa's protector. Despite these facts, Gabranth loathes himself for the framing of his brother and the horrible tasks Vayne and the Empire have commanded him to do, such as killing Drace to prove his loyalty as Archadia's "Hound". He accompanies Bergan and Zargabaath to Mt. Bur-Omisace where Larsa agrees to return with him, to avoid any trouble. Towards the end of the game, after realizing why his brother remains with a positive outlook despite his life ruined, Gabranth decides to make up for his wrongs by protecting Larsa and helping the Resistance kill Vayne for the good of the Empire. He is fatally injured by Vayne in the process, before Larsa arrived to his defense. After the battle, from aboard the Strahl, Basch poses as Gabranth to announce, along with Larsa and Ashe, the surrender of the Imperial fleet. At the same time, Gabranth lies in the back of the Strahl, mortally wounded. He dies after requesting that Basch takes up his mantle to serve and protect the new Emperor Larsa. In the aftermath of the game, Basch takes up his brother's request, serving as the next "Gabranth" and Larsa's protector.
