These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Justice League of Equestria
Complete Monster: Brainiac. Threatening to either fry a filly's brain or blow up an entire city of ponies just to get Rainbow Dash to see his point would qualify him for this. And that doesn't even count all the stuff he's done in the past, like stealing Kandor, for example.
