How do you play Junker Queen into Roadhog?

Title. Feels like he does everything that I can do, except for him it's way easier. If I get hooked, I instantly die, and since there is no way to punish him for missing a hook, it feels like I can never take space. It's also annoying to try to get a knife into any of the squishies with his giant hitbox clogging up main.
