Xensur

Xensur is an villian in Kingdom Hearts: Heartspawn. He is Number VI of the nobody group, The Final Six.

Post KH:H
At some point in his life, a young man named Ernus lost his heart. His nobody became Xensur, one of six secret experiments done by the late Organization XIII. He was trained by Axel and Saix, who's powers he obtained. Dispite being his master, Saix disliked Xensur because of his laid back, carefree atitude. They would often end up in arguments and fights during the middle of their training sessions, in which Axel usually had to intervene. One day, when Xensur was caught sleeping in the middle of his training, Saix became enraged and the two began to fight with their weapons. Saix nearly killed Xensur, sending him flying into a wall. Axel appeared just in time and stopped Saix with a wall of fire. Afterwards, Saix refused to train Xensur any longer, leaving Axel to finish the young nobody's training himself.

At the end of the project, one day before the Castle Oblivion Mission, Xensur and the other five "Successors" were presurved in sleeping pods for the future (their mission was to make up for the Organization if it was defeated). They woke up fourteen years later to find the Organization defeated. They then formed The Final Six and sought to restore Kingdom Hearts.

In Kingdom Hearts: Heartspawn, Xensur was posted at The Old Castle to collect heartless and search for the Heartspawn. He stormed the castle with the heartless but was stopped by Blain and co. He attacked the friends, trying to capture Blain. He was defeated, but recognised Blain's skill as a fighter. He even told Blain a bit about The Final Six's plan, hinting "They're gonna fininsh something that was suposed to be finished a long time ago!" and telling Blain that they wouldn't stop until they had him. He told Blain to watch his back and be careful with The Final Six. When Blain asked why Xensur would tell him this, Xensur only stated that he was giving advice to a fellow warrior.

Later, in The World that Never Was, Xensur kidnapped Kryke and Cath, telling Blain that if he left, Xensur would set them free. However, Blain pursued Xensur through the city, intending to rescue his friends and deliver his message to Sora's "friend". He cornered Xensur at The Memories Skyscraper and then battled Xensur. After his defeat, Xensur told Blain where he could find his friends and admitted that he had warned Blain earlier in order to help him escape The Final Six's clutches. Xensur said that he had intended to betray the other five, since he didn't think their mission was a just cause to reak destruction on other worlds. He warned Blain to leave and escape with his friends, since the five would easily overpower them together. Blain refused and claimed that he and his friends could handle the five. Blain thanked Xensur before he faded away and asked him if they would ever meet again, to which Xensur said that he wouldn't think so. As he faded he remarked that Kryke and Cath were lucky to have Blain as a friend.
