Recommendation book and Announcement book

I need a suggestion

Hello readers. I need help. I want to make another crossover with MGE, but I don't know what it should be crossed over with. I have only a few ideas.

1. Festus (From Rick Riordan) 1

2. Frankenstein

3. Destroyah 2

4. SCP-682 2

5. Your ideas.

Feel free to vote for any one you wish. Votes will close by Friday. See you soon! I'll keep updating my other books though, but I just want it start a new one.
