True. Nanoha and Co. are a bit more... combat oriented than most other magical girls. Prism Ilya might stand a chance, but even she remarked how crazy overpowered Nanoha was in the crossover. Card Captor Sakura might work if she got serious with a full deck. I wouldn't say Marisa Kirisame is really a magical girl per se, but her Master Spark might hold up against a Starlight Breaker. You know what? I'm making a list. I'd say most of them aren't even really magical girls, but hey, let's keep it interesting! They have magic and they are girls. Totally counts. I also picked out their 'Super Move'. Because I have too much time on my hands.
Yeah!
Just thinking about Nanoha vs Chise is enough to make my week. Actually, any fight with Chise against other Magical Girls is absurd, if only because Chise is the most disturbingly homicidal and broken magical girl ever created. Her opening line would have to be something like "You're all going to die anyway."
