He looks a lot like his brother Makuta miserix http://fc08.deviantart.net/fs70/i/2.....da-d6hziv4.png and yes that's Makuta miserix in the background on the far right of the picture!

Well, one dragon follows another ^^

Sadly Miserix was betrayed by Makuta Teridax long ago and was even left for dead! But he did manage to survive! After all, Miserix was the original leader of the Makuta Brotherhood long ago! Miserix was overthrown by Teridax in order to try to take over the Matoran Universe. Many other Makuta were on Miserixes side and rebelled against Teridax and were destroyed by him until only those willing to follow Teridax remained. Teridax once even sent his followers Antroz,Vamprua,Krika,Bitle,Gorast,Icarax,Chirox,Mutran,Spiriah,and many other Makutas on a mission that he knew they would not come back from alive!
