William the Kangaroo

William the Kangaroo is a character from Mystic Forest Fighters.

Bio
Although never seen in any of the episodes, William is mentioned frequently by Joey, his younger brother, and is described as a loving and kind individual who was apparently a very experienced and long-time member of the guild before his untimely demise. He is, however, finally seen in the movie "Mystic Forest Fighters - Case Closed" in a subsequent portal to another world that Joey had been sent through at the hands of Enchi. Here, William appears as a ghostly illusion and is shown to be mean and hostile towards his younger brother, stating how his father was entirely correct when he made false accusations about how Joey was the one who indirectly murdered his brother by begging to go to a supposedly dangerous crime scene before proper authorities could arrive and assist, being "very cocky" doing so. Joey, however, knew that this William was not the William he knew and loved, and angrily told him off. Casting away his own personal burdens by reminding himself that their father was the one behind all of these terrible sayings and was a major catalyst in Joey's hidden depression and self-hatred, aside from witnessing William's death.

Trivia

 * William died before the series began, being shot and killed by an ape after going to a dangerous crime scene before the Enchino Police Department could arrive and assist.
 * It could be inferred here that both Joey and William were cocky, believing that they could handle this task themselves without help.
 * It is unknown exactly how long William was a member of the Mystic Forest Fighters before his death, but only that he had been a member for a long time, even before Joey himself had joined the guild, meaning that William had to have been a member for over four years.
 * In the movie, the ghostly illusion of William is shown to be an exact opposite as what Joey had described of him throughout season one and what else could be judged about him through other comments such as those from Saad, meaning that the ghostly William could have had its personality skewed by Enchi to further traumatize Joey.
