How to Epic Monster feel more epic? Let's brainstorm!

We're definitely heading in the right direction, since dragons now have special attacks and a knockback, and Rift Herald has AoE autoattacks and weak points. I'm just throwing out some ideas for people to think on.

Blocks multi-target projectiles: by being massive creatures, they can block multi-target projectiles, such as Ezreal ultimate or Nami ultimate. Probably shouldn't apply to bouncing effects. Also possibly consider them to be champions for targeting purposes, so that they can block things like Warwick ultimate.

Can be crowd controlled, but has high tenacity and activates special attacks upon CC: shaking off a stun and the like would feel epic for sure.

More mobility: right now, the only epic monster that has a dash is rift herald, who dashes at the beginning of combat. Can we get more dashes/blinks? Dragons can swoop in after someone enters its pit, or do melee attacks that has a small dash component, somewhat like Rengar's passive jump. Herald is also pretty good, since it has a long leash range, which allows it to walk out to the River. Baron is completely stationary, and that can change. Maybe make it burrow and resurface occasionally, making it untargetable in the meantime?

What other ideas do you have?
