It is interesting to see that Tirek went out the way he came in on the show and both in his frail weakest form. The difference is that while Tirek was about to absorb power in his first appearance in the show, Tirek loses all of his power and gets turned to stone in his last appearance in the show. :P What a great character throughout! Tirek is one of my favorite villains on the show, alongside King Sombra, Queen Chrysalis, and Cozy Glow! His time throughout the show he mostly is spent in Tartarus, but he certainly made a huge impact the two times he was free in both Season 4 and Season 9. Even in his cage in Tartarus, he makes an impact in Season 8. A great villain and a great character overall! I wished we would've seen more of his backstory and his relationship with his brother Scorpan and his family, but other than that, he will forever be one of the most memorable characters in the show. :)
