If you noticed her boobs first, you're either a guy or a lesbian. That hat is surely more noticeable:
Pokemon: Cresselia
Ability: Dream Theater
Dream Theater is an ability that has been overused to the max in both Naruto and Bleach. If you guessed illusions, congratulations, you've got it right! Dream Theater allows the user to conjure illusions of the visual type. It cannot conjure sounds, smells, tastes, or 'spirit senses'. Dream Theater simply plants fake pictures on the target's retina to make them see things that are not there. This means that the user of Dream Theater is able to make different targets see different things, further confusing them. Cresselia has a kind heart so she usually creates fun illusions for little children. However, if you agitate her, you will see loads and loads of mind screwing imagery that will pretty much screw your mind. No, she does not troll people.
