Since the toy fare last year where you can clearly see the Shadow Sonic Boom figure sitting on the shelf I wanted to have him in my collection. But no more word since last year has been told about the figure so I couldn't wait any more and I made one of my own. I used the Boom Sonic figure as the base figure. I cut the quills off and super glued them back on pointing up. Then the rest I built up with Super Sculpy. And after the paint job there's finally Boom Shadow.
