The Hulk is a monstrous human creature. He has a deep voice, very guttural and stressed. I think you're all mostly familiar with how he sounds, but just in case, here's a video of roughly what I'm looking for. https://www.youtube.com/watch?v=DnasOLAkpTY

Try something you think works. I'm definitely down to try and work on the voice a bit in the call before the recording begins.

This may be a reoccurring role, so try to be open to future work as much as you can.
