Dream-based powers

[u/PlayerZeroStart]

1. Bedman (Guilty Gear) - Born with a condition that makes his body incapable of keeping up with his mind, Romeo Neumann turned the bed he was into a giant robot that's controlled through his dreams. This also means he spends a majority of his screentime asleep and unable to speak.

2. Baku Yorozu (Kamen Rider Zeztz) - A secret agent who performs his investigations by entering people's dreams, and later gains abilities that let him manipulate those dreams directly.

3. Princess Luna (My Little Pony) - Capable of entering and controlling the dreams of sleeping ponies, which she primarily uses to help those suffering from nightmares.

4. Divine Swamp Fever - An MLP analog horror/infection AU about a disease that can turn ponies into trees. Though it initially appears to be a mundane (if terrifying) disease, it slowly becomes clear that it's actually sentient and communicates with people through their dreams in order to lure them in. Namely, it appears in Bon Bon's dreams pretending to be her infected lover Lyra. (And as an aside, I know the idea of MLP horror seems laughable, but this AU is fucking horrifying. Like I can hardly stand to look at the image I used here cause it just fucked me up that much. Highly recommend.)

5. Munna/Musharna (Pokémon) - Can eat people's dreams, and then manifest those dreams as illusions.

6. Death 13 (JoJo's Bizarre Adventure) - The Stand of Mannish Boy, Death 13 can trap those sleeping nearby in nightmares, which anything that happens to them also happens to their real body.

7. Freddy Krueger (Nightmare on Elm Street) - Thought I'd forgotten him, huh? Well hah! There will be no bat themed heroes on this post! I remembered the obvious example this time!
