"What, ho! Dost thou ponder the curious countenance of yon emerald-clad highwayman? 'Tis that villain of greatest renown, the Angry Archer! (real name Aaron A. Archer). Armed with naught but his wits, his trusty bow, and a profusion of wizardly-empowered arrowheads, the Angry Archer is the very scourge of olde Detroit town!"

Just do a voice that talks like that if you want. Or you could do a Hawkeye/Green Arrow voice and tweak the auditions lines to say them normally.
