Sharukurusu

The Sharukurusu (シャルクルス) is a humanoid Reaverbot with each of its arms and legs attached at the same joint place. The Sharukurusu is a fast-moving Reaverbot which attacks by charging with its piercing claws, being capable of knocking down the target onto his head when it charges into him.

Mega Man Legends
The smaller Sharukurusus are green-colored and about the same height as Mega Man Volnutt (maybe a few inches taller). In the Lake Jyun Sub-Gate ruins, there are blue Sharukurusus with the ability to become transparent and sneak up on an intruder. In the Sub-City Ruins, they appear in a larger, pink-colored form. Guynie Toren drops Sharikurusus.

Mega Man Legends 2
Two large pink Sharukurusus appear in the Kito Caverns in Calbania Island, where they act as guardians for the yellow Refractor. Green Sharukurusus appear in the Calinca Ruins and in the Digger license tests from Yosyonke City's gallery.

Mega Man Legends 3
Sharukurusu were planned to appear in Mega Man Legends 3, where they would have attacked Klickelan Island alongside other Reaverbots.

The Misadventures of Tron Bonne
Large pink Sharukurusus and golden Furiferis come out endlessly of the Colossus in the last mission. The Servbots can hold them for a short period.
