- Flerovium (INTJ)
Isn't good at small talk, hates stupid assumptions, and considers her sister Lead to be one of her biggest role models besides the plumber's crack she possesses.
- Silicon (INTJ)
Is not slutty like her sister Carbon, likes the internet/computers, good at analyzing information, and is kind of a loner.
- Krypton (INTP)
Claims to be the smartest Noble Gas, but ruined her voice by singing like shit (she thinks it's not her fault though).
- Kesha (ENTP)
Was an egotistical brat with the Monster High ghouls but as she distanced herself away from them (especially Lagoona), she realized that she is actually quite knowledgeable and only counts Mackenzie as her best friend.
- Nickel (ENTP)
Says that she is proud of being a part of a privileged majority with enough money to survive, but also wasted a precious month on trying to troll the Monster High ghouls.
