The very first power Stella received was something she gained on the day she woke up on the island. Her powers had evolved to a point where she could make inorganic matter as well, albeit at a minute amount.
She could create a whole chuck of rock or a large knife, but the amount of energy she would have to use up for them was way too absurd for her to ever do it unless absolutely necessary. She could, however, create some salt, and some minerals directly with the organic matter without spending too much energy, all of which proved handy when it came to making foods.
Her powers continued to fester for the next few days until she gained another power just earlier this morning, where she gained the power to convert matter itself.
Then, after she was sent into the video game, she did well in the dancing game and extremely well in the racing one. She did however do poorly in the fighting one, causing her to lose her first ability to create things for several days.
