Winx Club Forever
It has a certain resemblance to the dragons, but only this one has some scales like crocodiles (lizards). It has three heads, glowing green eyes, sharp teeth, and grey scales.
In "Acheron", after the Winx made Cloud Tower back to normal. Acheron did not give up and decided to invoke the Great Lizard Spirit below Cloud Tower to attack the Winx. Bloom decided to go alone to Legendarium while the others were still fighting the beast.
It can shoots out blue color electricity like the Electropus.
- When Acheron says it is a lizard, rather it is a dragon.
- It almost looks like 3D when it is invoked, this the only creature that looks like this.
