This thread is a wiki for hero voice lines.
Just pick a hero to see what they have to say!
If you’d like to help complete our list, just click the edit button in the lower right corner of a hero’s post, and add a voiceline that you’ve heard. Please try to use the same formatting for all heroes. @alhunterr 's Voiceline Series on YouTube might be helpful. Thanks in advance!
