A long time ago in a universe far, far away~ Comes Recorder! Or Record for short. Either way chances are that's not even her real name. As she states such information is against protocols and thus is highly classified.
Record comes from an equally mysterious academy which sends her out into the field to study the dynamics between hero and villain and will often accompany either one to gain further nsight, Record Stata, and send them back to the academy and the universe to where originated from. What happens to that information is generally unknown aside from her and those remotely involved.
What is known is that Recorder sports a genuinely bubbly personality and positive outlook on most occasions. She has an affinity for sweets~ especially sweet rolls, and actually gets overly excited in combat. Some heroes often claim that there might be a darker secret to Recorder's personality, perhaps even unbeknownst to her. But she rarely if ever shows open hostility to her companions, rather focuses her sadistic enjoyments on enemies.
