“What a lovely day!”
The clever and stealthy Vampire Bat may be his monster master’s chief hench-bat, but he isn’t entirely thrilled by wicked schemes to eclipse the sun and plunge the world into eternal darkness. After all, he might be one of the children of the night, but that doesn’t mean he wants to spend all his time there!
In fact, the Vampire Bat actually loves being out in the daylight. Sunny days at the beach are his idea of perfection (though he does get a lot of sand in his fur and it’s not easy to see through the glare when your eyes are so well-adapted to the dark). Now that there are a bunch of human monster-fighters trying to foil his master’s plans, he’s secretly rooting for them to win!
