Ash  

Chrono Number X

In the manga, Ash and Chronos Number X were close friends who partnered together. However, unlike in the anime, Ash never physically appeared in any of the volumes. Instead, it was revealed that he had been killed by Creed Diskenth. On the other hand, in the anime, Ash does appear and is shown to wield a cane as his weapon, which may be a shikomizue. Additionally, Ash has an "X-shaped" scar on his forehead, which is concealed by his bandana. In both versions of the story, Ash was ultimately killed by Creed.
