Sirenix is the second transformation of Season 5. It is water related and the Winx looked for this ancient power to fight the villain Tritannus as their Believix powers were too weak underwater. Stella’s attacks come from the Sun, Moon, and Stars, but practically all of her attacks are sun-based. This may be because she comes from Solaria, where she is the princess, and this gives more emphasis to the Sun. Stella’s attacks are mainly based around light and heat, which can be explained by her connection to the Sun. Stella can throw blasts of sunlight energy and can make balls of solar heat. She has also used an attack called Sun Burst which burns things.
