"A Keyblade infused with Getter Rays. The three parts of the blade can be rearranged for varying effects."
123- Balanced stats, enables use of Getter Beam
231- Superior speed and magic, enables use of Getter Drill
312- Superior strength and defense, enables use of Getter Smash
Hopefully someone else can do a Getter Robo G-themed Keyblade with the same mechanics as this one.
Special thanks to Go Nagai, Ken Ishikawa, and Tetsuya Nomura.
