Sharp Edge

Sharp Edge (シャープ・エッジ) was one of the seven original lizardmen tribes that inhabited the Great Lake.

Background
In the past, a war over the scare resources within the Great Lake erupted between the lizardmen tribes. Two camps were formed among the fighting tribes. The three tribes; Green Claw, Razor Tail, and Small Fang joined an alliance. While Yellow Speckle and Sharp Edge formed their own alliance as well. The outcome of the war ended with the three tribe alliance's victory. Sharp Edge was forced to disband, with survivors being absorbed by Dragon Tusk.

The Lizard Man Heroes Arc
When it was proposed by Zaryusu that they form a grand alliance with all the remaining tribes to combat the Supreme One, several tribesmen were hesitant of the idea. The reason being that Dragon Tusk contained survivors from Sharp Edge and Yellow Speckle, and would possibly still hold a grudge against Green Claw and its allies.

Strength
In the Anime, Sharp Edge was described as being proficient in sword skills.

Trivia

 * During the ensuing battle, Sharp Edge's Chieftain was slain by Zaryusu Shasha.
