He then activated the Chameleon Veil brain crystal power, which made it possible for him to vanish from public view. His body began to shimmer, becoming as transparent as a glass panel. His outlines were difficult to make out against the steel walls that had been polished.

In addition, anyone with heightened senses or the appropriate equipment could still detect him; as a result, Erik also wore a mask to conceal his identity.
