interactable

What are some Batman strings that you can combo into stage interactables? What are some strings to use after the opponent bounces back?

Edit: Non of these work any more due to an early change that prevents you from releasing drone during the relevant interactable animations. Keeping them all up for the swag factor. Brainiac's trait allows him to delay a projectile for about 7 seconds as long as he doesn't get hit or take chip...
