Want to see Oliver meet Robin Hood? Want to see Doc Brown and Rip Hunter argue about time travel? Want to see Quicksilver race The Flash? Well this is the blog to do just that. You can place your ideas for crossovers in the comments. What world should the Arrowverse interact with? That is up to you.
So far I've gotten some interesting ideas. I can't wait to see what you creative and clever users can come up with.
