Samarium Cobalt

A specialized combat drone created by Carolyn Storm - a skeletal body with control over magnetic fields and a large quantity of ferrofluid, allowing for limited shapeshifting. Was defeated by the Starlight City Champions and stored in their trophy room - after their death, somehow attained sapience and escaped from the base with their trophies.

GM-Level Lore Her sapience was the result of one particular trophy, an artifact that contained a small quantity of eldonium and, unknown to the Champions, had a leak. Exposure to it, over time, connected her circuits to the Dreamlands as well as Cyberspace, resulting in her becoming sapient.
