Echo is an elf who works for Santa in the South Pole, not much more is known about the character but they work very closely with Santa-Man as well as with their buddies, Delta & Tango -- Echo is the leader of the three who usually takes charge. They can be played by either gender but should have quite a high-pitched & childish voice -- think like the elves from movies like Arthur Christmas -- if you recieve the role, you shall expect to return for more films as the character.
