The Zhuge Siblings

"The Leaders of the Gan Jiang Progeny and the Mo Xie Progeny are fraternal twins; that's why they look somewhat similar," Gongsun Jing promptly explained upon hearing Huan'er's words. "Individually, they're no match for my grandfather or the sect leader. However, if they join forces, they'll have the advantage if the fight drags on." Then, he lowered his voice before he continued to say, "Rumor has it that in the past, a titled Celestial Emperor who tried to conquer the Nan Dou Territory was killed by them. When they join forces, not only in the Thousand Tribulations Sword Sect, but they're also invincible in the entire Nan Dou Territory. As twins, not only do they think alike, but they've also comprehended the extremely powerful Fusion Method."
