So a new Lego set that really surprised me was announced, which is Super Sonic and Super Shadow vs the Biolizard from SA2. Its existence makes me wonder if the movie will in fact have the Biolizard after all, especially because Shadow was silver in this scene (iirc Hyper Shadow).
Maybe the movie recons it as two golden super hedgehogs resulting in the depiction in the set. But just a guess.
