BY UNDEADAWE: Problably, since Chroma came out during the "Ultimate Alien" season, and is in the ULTRAmatrix.
Ultimate Chromastone hasn't been invented yet, but im sure in a future season he might appear
Swampfire is strong but Chromastone would win.Swampfire can only use fire and plant while Chromastone has the power to control diamonds and generate ultraviolent attacks.Even If it was Ultimate Swampfire vs Chromastone,Chromastone would still gain the victory.When in Ultimate Form he still only has fire but a blue fire which makes it more powerful.Chromastone can block that attack by creating energy sheilds.then he can attack with absorbed energy creating Ultraviolent rays.
On DS you can only be Swampfire,Humongasaur,Echo Echo,Chromastone and Goop.
