Personality: Belonging to 2 clans, Promethium, being a easy-going person she generally goes well with most her allies. Although she's technically a Lanthanide, she's much closer to the Radioactive Alliance (RA or Mjolnir), both because of her radioactive status and culture reasons. She's a big nerd on Greek mythology and ancient history, and thus she can speak quite good Greek together with English and native Lithuanian. However, she can be too dead-pan and reserved: once she runs into a certain problem, she'd rather grinding and fixing it instead of offering help from her allies. She's once even said to be "too dull and nerdy", according to Actinium. She may be caught in greater trouble with her personality, on another side she's very calm and rational; perfect to handle serious stuff. Promethium's best friends are Thorium and Radon, they're always shown working and having fun together. After Radium had retired from the Nightime Special Department (Organizing nightime researches and evening activities for ELemental Warriors, and Ra's power had caused chaos in the Research Institute), she had taken the role with Tritium ever since.

Due to her frail physique, she's usually seen trembling and cries easily. Characterisation based on Latvia and Lithuania from APH

Trivia:
* Promethium's very aware and hates comparing her "size" with other Radioactive girls, being the flattest among the flock
*She's also a great artist and musician- can play the lyra very well
She faints when seeing blood and bees, despite her radiation can expell and kill bees from approaching her
