Krillku

&nbsp Krillku is the outcome of Goku and Krillin fusing with the fusion dance. These two were able to fuse because Krillin trained and trained to become as powerful as Goku and he became as powerful as him and they fused. Trunks was suprised that they were able to fuse because Goku can go up to the last form of a Super Saiyan and Krillin isn't even a Saiyan.
