- Cool Old Lady: She listen and gives good advice to Ruby about her friends turning into jerks.

Grandma van der Troll
One of the five Ancients who is not only Amethyst's grandmother, but is also her granddaughter's Ancient. Similar to Obsidian, while Grandma van der Troll is obviously closer to Amethyst than the other four members of BFFL, she mentors all five of them as a whole and is always eager to listen or help if the situation calls for it.

Zirconia
Topaz's Ancient who also happens to be Spinell's wife. She fought Simon long ago alongside the other Ancients, but it came at a cost—he imprisoned her within a tree for 3,000 years, draining her magic. At first, Topaz was in denial of Zirconia being her Ancient, but eventually came to accept it, especially when she and Zirconia bonded over a common interest in fashion.

- And I Must Scream: Spent 3,000 years as a dragon who couldn't talk.
- Cool Old Guy: Though more snarky than the other Ancients.
