Bio: Hatched a day after Thorax's hatching, Amber also felt different compared to most others of her kind. Like Thorax, she was inspired by the Mane 6's strong friendship attempting to fend of the invasion of Canterlot and never regrouped with her own species. The two never met for a time, but when she heard of Thorax's effort's in the Crystal Empire she became a bit more confident in her secret visits to Fluttershy, socializing in Ponyville (in disguise) and started distancing herself from The Everfree Forest. She later followed the rescue team back to her birthplace at a distance and witnessed events play out, almost exposed when Starlight said "Give Her All Of It!" She metamorphosed along with her kind and stood firm against the then-former queen. She later finally introduced herself to Thorax and has been appointed as a co-ambassador ever since.

Nowadays, you might see Amber in Canterlot at U.S.F. or similar meetings, at the hive reporting her activities or in Ponyville improving her social skills and character. Occasionally she ventures further in efforts to improve relations with other species.
