Radial Force Against AI Navigation

I’m trying to mod a game I made from the Twin Stick Shooter tutorial by Zak Parrish. I want the hero to do a radial force against the AI enemies to push them back. I’ve figured out how to affect them, but their navigation toward the hero is usually too strong to allow physics. How could I make them ragdoll for an instant to allow the physics? Thanks.

EDIT: From what I’m seeing in the documentation, it seems like AI characters must choose to be affected by the physics using the behavior system. I’ll have to learn about that when I have time.
