The Mikado Arm looks like two golden arms holding onto one another at either end.
Abilities[]
Superhuman Strength - When activated, the two golden arms slid down into the arms of whoever was using the Wu, and it granted the user incredible upper body strength. The user's arms also became extremely long and durable, enough so to survive laser blasts and a full on punch from the Fist of Tebigong.

Did You Know...?[]
Dojo stated that the Mikado Arm is one of the lesser known Wu.
Omi was the only character in the series to use this Wu.
This is the last Wu to be revealed in this series.
It's never revealed how or why the Wu was on a construction site, although one theory points to the workers using it to aid in construction off-screen.
If so, this may very well be the first use of a Shen Gong Wu used in civilian hands for commercial purposes.
