Raziel

Raziel is a vampire-turned-wraith who came to join the Apprentices of Caiaphus. After deserting the order, Raziel used his power of time travelling to monitor the timeline of the Original Universe. Upon discovering the existence of F-Klak, Raziel began working against him. In recent days, Raziel has allied himself with Mazkertis, with his reason being that the erasure of Klak from the timeline will prevent F-Klak's dark future from ever existing.

Early life
Most of Raziel's life before he joined the Apprentices of Caiaphus resembles that of his counterpart in the Legacy of Kain series. Raziel was originally a human, but in time became a vampire. Raziel came to serve Kain, a vampiric warlord in his home realm of Nosgoth, and became a lieutenant in his army. Raziel eventually became more powerful than Kain and was executed as a result. However, he was revived somehow and became a wraith with several new powers. By using his newfound abilities to travel between dimensions, Raziel became familiar with the BZPB Omniverse, and encountered the Dreamkeeper Namah when she visited Nosgoth on at least one occasion.

Apprentice of Caiaphus
Eventually, Raziel met Caiaphus and pledged allegiance to him, becoming one of his Apprentices. In one of their battles against Klak's allies, Raziel killed several Malchiorians and knocked D-Klak unconscious, but retreated when the Malchiorian forces gained the upper hand. (This was Raziel's first appearance in BZPB.)

When the operators of the UG brought the pocket dimension into the Original Universe, Raziel sensed its presence and decided to investigate. Inside, he found what was essentially a large banquet of souls for him to feast on, in the form of many depowered characters, both living and dead. Raziel immediately feasted on the soul of Tidal Wave, a fellow apprentice of Caiaphus. This treachery was not taken lightly by the other apprentices present, who all teamed up on and defeated Raziel, causing him to flee back to the OU. Later, Raziel sensed the reaving of souls elsewhere in the universe and teleported to that location. There, he was reunited with Namah, a Dreamkeeper who he had previously met on his travels, but she did not seem to want his help against whatever forces plagued her. Raziel disappeared once again.

Fixing the Future
After a brief absence, Raziel reappeared inside F-Klak's chamber in the far future, where he expressed knowledge of F-Klak's activities. He told F-Klak that Klak must not be pushed towards the dark side, but F-Klak disagreed, saying that not only is it both his and Caiaphus's will, but also Klak's destiny. Raziel remained with F-Klak to monitor his attempts to change the timeline. When he discovered that F-Klak was communicating telepathically with Praepositus, Raziel visited the soldier at Kakamu's funeral and asked him about their relationship. Praepositus denied knowing who F-Klak was, so Raziel told him about F-Klak and the dark time he hails from. F-Klak, however, twisted Raziel's words to convince Praepositus that he had to kill Klak.

When Praepositus told Perseus about the existence of F-Klak, the Toa called him a madman. However, Raziel appeared to them and supported what Praepositus was saying. He then went to guard the Norman to protect her from F-Klak, but his efforts were in vain, as F-Klak overpowered him and took the Norman anyway. When Klak and his friends returned to find the Norman missing, Raziel told them what had transpired before disappearing once more.

Raziel was next seen conversing with Klak at a ruined temple that once belonged to Caiaphus. He encouraged Klak to abandon his friends and seek out a power that would enable him to defeat Blackout, Uterio, and all the other villains plaguing him. When Klak questioned Raziel's allegiance, he replied that he serves no master but himself. Raziel then vanished for several months, returning only to tip Sasuken off about a grander scheme and spying on Vez. He encountered Klak again in RacKoon City, during a viral outbreak unleashed by F-Klak. Raziel angered Klak by comparing him to his future self, so they duelled again, but Raziel vanished before either one of them could gain the upper hand. Eventually, Raziel ventured to the Project Cadmus cloning facility on Korasa, where he discovered the truth about F-Klak's origin.

The Truth
Later, Raziel travelled to the future again, but this time to warn F-Blackout not to meddle with the past. F-Blackout had his men restrain the intruder, but Raziel disappeared. He was next seen at on Malchior IV, where he freed a bunch of prisoners on the condition that they served him. While leaving the prison, he bumped into Abneris, DM Helryx, Ferret, Kithlara and Mink. He summoned the Soul Reaver and clashed with the group, but paused when Klak arrived and asked him what he was doing there. Raziel revealed that he was under orders to remove them from the timeline. He attacked Klak with the Soul Reaver while also intermittently fighting off Ferret's and Mink's attacks. When asked to explain himself, Raziel told Klak that he freed the prisoners so that they will create a movement on the planet against him. Klak angrily swung at Raziel, but the wraith disappeared again.

Raziel was next seen on Malchior IV's moon, where he eavesdropped on Coro and TPK. Coro and Axalara recognized him from the prison breakout, so the latter attacked him and demanded answers. Raziel told them about his role as a time-travelling historian of sorts, and revealed that Klak is not dead, F-Blackout is in the present somewhere, and that the present Blackout is working with Ra. When TPK asked more, Raziel told him that he had already said too much and disappeared again.

The Mazkertis Paradox
Some time later, Raziel reappeared at Mazkertis's side following the latter's battle with Drepp. Raziel revealed to Mazkertis that he had been watching him over the past few weeks and found that he shared his goals. He pledged his allegiance to Mazkertis and became the first member of the Kindred of Dawn as a result. When their allies the Lurians discovered the Eclipse Spiral, Raziel went with Blue and the Green Goblin to investigate. They found, freed and fought Ludwig von Todesfal, a Great Being who had been in stasis since the start of the Uterio War. When Ludwig surrendered and submitted to them, Raziel decided to take him back to Mazkertis for the wizard to decide if he had any use for him.

One of Raziel's next missions was accompanying Mazkertis to Datrio, serving as support while the wizard generated a massive, life-draining spell to increase his power. When the Claws of the Phoenix arrived on the planet to stop him, Raziel appeared in front of his former master Caiaphus and engaged him in combat. While Raziel initially gained the upper hand, he was soon overwhelmed by the Makuta's Kraata powers, and was defeated when he was flung into the sea.

Abilities & Powers
Raziel travels via portals of his own creation that can lead to any location in the universe or to and from the realm of Nosgoth. Raziel possesses the ability to heal himself by feeding on the souls of his victims. This is a process that must be repeated every so often; if he goes long periods of time without feasting on souls, he will become severely weakened or possibly even lose control of his form. Raziel can devour souls without the aid of his sword, the Soul Reaver, but chooses to use it to do so in most cases. Raziel and his blade can sense wherever souls have been devoured elsewhere in the universe. Raziel can shapeshift, as evidenced when he took on the appearance of a Malchiorian during the Uterio War. Raziel can turn into a "spirit form", which allows him to fly and become intangible. Raziel has displayed the ability to travel through time, though where this power originates from is unknown.
