Catalyx is a being of unknown origins who serves on the Enterprise. He is a skilled pilot. He is said to sound like Soundwave, from the G1 Cartoon of the Transformers fame, from which BZPB draws much of it's backstory from. He was floating around in space, due to the explosive decompression on the bridge of the Enterprise. He died after he crashed into Chenrotoss, but his life essence created the Toa Catastras.
