The Golden Tri Scythe is a Ninja weapon used mainly by Cole. It is a golden scythe with a long shaft and a three-pronged blade called a golden Little Striker.
It may be intended as a improved form of the Scythe of Quakes, given its explicit association with Cole and its ability to transform into a car that can be camouflaged as a snake.
Cole's Golden Tri Scythe is the ultimate Serpentine repellent you'll ever come across. Enough said. And then again, we should mention that it also turns into a car that can be camouflaged as a snake. Handy for infiltrating Serpentine lairs.
