Forum:Future Fusion and Vanity's Emptiness

A friend and I were dueling. He had Future Fusion out and was going to summon Cyberdark Dragon during his next standby phase. I had Vanity's Emptiness out on the field to hopefully prevent the special summon. My friend insisted that since Cyberdark dragon was a fusion summon and not a special summon he could still summon Cyberdark dragon. Which one of was right? Would vanity's emptiness prevent future fusion from resolving?Vanity's Emptiness
