YMMV / Mattimeo

• Complete Monster:
  • Slagar the Cruel, formerly a wannabe thief and accidental murderer named Chickenhound, reinvented himself as a kidnapper, slaver, and mass murderer. Capturing the children of the Abbeydwellers, and several others, Slagar plans to sell them into slavery in the nightmarish Kingdom of Malkariss, where they will be worked to death by a tyrant. Along the way, Slagar proves himself the worst boss in the series when he runs Hairbelly through for complaining, hurls Wedgeback off a cliff for letting some slaves escape, wrongly executes Vitch (who he had previously tried to sell into slavery) for talking to Matthias, and in his most impressive act of treachery, convinces his entire gang to slaughter one another, so that he can keep the profits for himself. Completely untrustworthy, and intent on one day betraying Malkariss as well, Slagar is as underhanded and manipulative as Redwall's villains get.
  • General Ironbeak, the fiercest fighter of the north, is a refined yet monstrous character who leads his followers to conquer Redwall Abbey. Arriving at the Sparra loft, Ironbeak massacres the elderly and baby sparrows who were left behind to take over and proceeds to launch attacks on the abbey. Upon taking over Redwall, Ironbeak reveals he intends to massacre the population, who are all innocent civilians and little children, at least one of them only a baby. When he attempts to attack the abbot, one of the abbey residents tries to protect him, prompting a furious Ironbeak to attempt to kill her on the spot.
  • Malkariss is the evil slaver employing Slagar, and the biggest villain in the novel. An Unseen Evil for the majority of the book who rules from a towering statue in his likeness, Malkariss's kingdom is built upon an engine of child slavery, with hundreds of young woodlanders kidnapped from all over Mossflower to slave away under constant starvation and torture until they finally die. The widest scale child-slaver in the franchise, Malkariss is ultimately revealed to be a haggard, frail, helpless old polecat who has consumed the lives of countless children as a means of compensation.
• Fridge Brilliance: The Wearet, described as a hulking, primitive-looking beast like a cross of a weasel and ferret but with no visible ears and hardly any neck, greatly brings to mind a cynodont to those familiar with prehistoric life: cynodonts were primitive proto-mammals of the Triassic period that greatly resembled small carnivoran mammals, but notably lacked external ears as their ear bones were still part of their jawbone.
