3. 彼得·佩蒂格鲁（320）

3. 彼得·佩蒂格鲁

彼得·佩蒂格鲁（别名“蠕虫”）是哈利父亲曾经的好友和四人帮成员。他起初被描绘为一个胆小如鼠的角色，后期揭示出他是出卖哈利父母的邪恶角色，一直伪装成罗恩的宠物老鼠斯卡巴斯。佩蒂格鲁的出现增加了故事的悬念和惊喜，展示了懦弱和背叛的主题；他的行为出于自保而非忠诚，造成了冲突和紧张。当哈利、罗恩和赫敏揭露佩蒂格鲁的背叛时，忠诚的复杂性和选择的后果成为核心主题。最终，佩蒂格鲁与哈利的对抗彰显了对责任和过去行为的承担。佩蒂格鲁体现了友谊的黑暗面和潜在的背叛，与系列中其他角色的忠诚形成鲜明对比。

3. Peter Pettigrew

Peter Pettigrew, also known as Wormtail, is introduced as one of the former friends of Harry's father and a member of the Marauders. Initially described as a timid and rat-like character, he is revealed to have played a crucial and treacherous role in the downfall of Harry's parents by betraying them to Voldemort. His return to the story as the animagus form of Ron's pet rat, Scabbers, adds an element of intrigue and surprise. Pettigrew's character illustrates themes of cowardice and betrayal; his actions driven by self-preservation rather than loyalty create conflict and tension. As Harry, Ron, and Hermione uncover the truth about Pettigrew's betrayal, the complexities of loyalty and the consequences of choices become central themes. His eventual confrontation with Harry brings forth the significance of accountability and the weight of one's past actions. Ultimately, Pettigrew embodies the darker aspects of friendship and the potential for betrayal, contrasting sharply with the loyalty shown by other characters in the series.
