Stormer's ice missile launcher had tips made from Legends of ChimaChi crystals, however this was changed to light blue studs later in development.
It also appears that Stormer has Furno XL's shield piece and a silver sword, but it was blue in the trailer.
Stormer, Furno, and Surge are the only Heroes that have printed visors in the Brain Attack wave, and have shield parts.
