Erin (Patreon)

 A former spy for a secretive organization that infiltrated Emily's lab to steal the information on The Change. She got caught, however, when Emily returned to her lab earlier than expected, and the water elemental quickly subdued her. Rather than imprison her, Emily simply injected Erin with The Change - a particularly powerful strain at that - resulting in a bug girl that is constantly producing eggs, much faster and in larger quantities than Alice or Molly. She's now stuck at their compound, but reluctantly plays nice with the others because she's reliant on care workers due to her extreme production.
