First of all, for Dark Tiga Altman, his popularity can be said to be the highest at present, but for Diga Altman, besides the well-known Warrior of Light, he actually has a dark side. Di Jia is a warrior from ultra-ancient times. At first, there was a slow dark force in his body. At first, Dark Tiga, Camilla, Chitra and Dalam were merged into the Four Dark Warriors. Humans existed on the earth in ultra-ancient times, and they created early civilizations. Moreover, there were many giants like Diga in ultra-ancient times, but the previous super-civilization was on the verge of extinction because of the later civil war. At the end of the civil war, the Dark Four became the ultimate winners, and they became the world hegemons. But then Diga Altman was persuaded by Yu Ling, the captain of the Super-Ancient Earth Guard, to give up the darkness, defeated the other three dark giants, took away their own strength, and then accepted the baptism of light, so he became a righteous man of various forms.
Actually, it's dark Ciro. Let's talk about Siro's strength first. Like Dijia, he belongs to the multimodal Otto warrior. Cerro Altman is the son of Severn Altman. He is the first Otto warrior in a new generation, and he can fully reflect the temperament of our younger generation. Eager for great power, like beria, he wanted to touch the artificial sun to enhance his strength, but was stopped by Severn Altman at the critical moment. Later, I received the devil training from Leo Altman. The dark Ciro is actually a form of Ciro Altman, because it is possessed by an old enemy, so it is an evil side. In the second part of Super Siro Fighting, beria becomes a dark armor beria, and enters Siro Altman's body in the form of soul, occupying Siro Altman's body and making it a dark side. Moreover, beria's evaluation of Dark Ciro in the play is "the strongest body in the universe", and the members of Ciro Cosmos Guard are directly killed by one move when they stop Ciro Altman. However, in the end, due to the birth of the new form of Ciro, beria was killed and returned to the former warrior of justice!
So for the strength of Dark Tiga and Diablo, I personally think Diablo is stronger. One of the reasons is that against beria, everyone knows how strong beria is. And that is, according to the official setting, Diablo is the strongest dark warrior!
