It is also shown in this series that depowered mutants, if exposed to the Terrigen Mists, gain an uncontrollable version of their former powers. For example, the Mists restore the hyperacute senses of Callisto, but all the amplified stimuli cause her to fall into a coma. However, the effect is only temporary as powers fade after a short while. As shown with Quicksilver, the bodies of those exposed to the mists for extensive periods begin to produce their own Terrigen Crystals with the same mutagenic effects. At the end of the Son of M series, the U.S. government confiscates the Terrigen Crystals dropped by Quicksilver, which leads Black Bolt to declare war on the United States.
