Julie-Su was entrusted into her care by Luger after an "accident" claimed her mother's life and he could not look after her. Before that, she and her husband were heartbroken about Julie-Su's situation and relationships with her half-siblings. When Luger disappeared, Kragok and Lien-Da had Julie-Su's Memory Neutralizing Chip activated, wiping out her memories. They then told Floren-Ca to pretend Julie-Su was an orphan and that she was the only parent figure she'd even known. She and her husband raised her as if Julie-Su is their own daughter and truly care about her. When Simon had failed to be killed after Kragok had assigned him to an ill-equipped unit for supply raids, he and Lien-Da had Julie-Su taken from Floren-Ca when she was raised by her about eight years and had her become a Dark Legion soldier, fearing they might tell Julie-Su the truth of her past.

Reunited with Julie-SuEdit
Years later, Floren-Ca was taken prisoner along with Simon and Julie-Su on board the Battle Cruiser, as Dimitri felt they were as much a part of family as Moritori Rex was, and did not want them to be sent into an alternate zone when the Quantum Beam was fired. She is relieved about Julie-Su's safety. (SSS: #14)
Floren-Ca, Simon and Julie-Su were kept confined to a cell for a time, until Chaos Knuckles arrived on the Battle Cruiser. Lien-Da brought Julie-Su to the bridge of the ship to use her as a bargaining chip to gain Chaos Knuckles' allegiance. (StH: #100)
After Chaos Knuckles restored the Echidnas back to Angel Island by undoing the effects of the Quantum Beam, he pulled some strings to get Floren-Ca and Simon an apartment in Echidnaopolis. Floren-Ca later appeared at Knuckles's funeral with Simon. (StH: #114, #121)
- Floren-Ca's fate remained ambiguous for some time. While Simon was seen to be a victim of the Egg Grape Chambers in StH #141, there was no indication she had fallen to the same fate. She was not been seen since Sonic the Hedgehog #121. Her fate in the Egg Grapes was finally confirmed in The Complete Sonic Comic Encyclopedia.
- In her first appearance in the present time (SSS #14) Floren-Ca was seen with dark purple fur with a teal dress and no glasses. In her second appearance, (StH #100), Floren-Ca was seen with red fur, glasses and a blue dress and looked rather elderly. In her last appearance (StH #121) she was seen with red fur, glasses, a gray streak in her hairline and wore a black dress for Knuckles's funeral.
- Originally, Floren-Ca's design was going to be used for Julie-Su's birth mother, but it was later switched for the model that became Mari-Su in the final version.
