You're seen running from the Angel, known as Sachiel. The creature roars in anger, destroying everything. It's about to catch you. Until...

SPREAK!!

Something stabs Sachiel. It's revealed to be a giant robot, known as Evangelion Unit 1. Or Eva-01 for short. It cannot speak, but it can growl and roar and also howl in responses. The Eva kills the angel and roars into the sky. You stare at the Eva in shock. Just as the Eva sees you, it calms down. Showing no murderous intent, but calming.
