Harry Potter vs Marnie

Harry Potter is so much cooler than Marnie and not to mention braver and tougher. Harry was put in the Gryffindor house which is known for bravery whereas if Marnie were to go to Hogwarts she might be put in Hufflepuff since that is the most plain of all the houses and its the default house, if you don't qualify for any of the other houses you get put in Hufflepuff, so Marnie might either be put in Hufflepuff or possibly no house at all since she might not even qualify for Hufflepuff let alone any of the other houses.

Aside from all that though, the main reason why Harry is so much better than Marnie is that Harry puts up more of a fight against his guardians when he's treated unfair than Marnie does. The Vernons go to every possible length to keep Harry from going to Hogwarts and learning magic and yet Harry keeps on fighting and ultimately prevails. When Gwen, Marnie's mom, tries to keep Marnie from learning magic Marnie does not put up much of a fight. She submissively and weakly goes along with her mom when her mom isn't being fair. The most Marnie does to rebel against her mom's unfairness is when she sneaks off to follow her grandmother and takes the bus to Halloweentown which if you ask me is a cheap excuse for Gringott's Alley. Particularly though, when her mom tells Marnie to put down the broom and that she's grounded Marnie gives in. Harry would never give in like that. Harry fights the Dursleys every time they try to keep him away from learning magic and even brandishes his wand at Vernon in one scene. So Harry is way cooler than Marnie.
