- "Our uniforms were exposed to the storm, like us so they can transform like us.becoming invisible, changing size on demand or remaining impervious to flame.!"
- ―Reed Richards
When the Fantastic Four go into combat, they have specialist uniforms required for their mutation.
The uniforms were originally designed by Victor Von Doom for their project into space. The synthetics acted as a second layer of skin, therefore adapting to the body's individual needs.
When the cosmic storm hits, their uniforms became exposed, therefore adapting to the individual's mutation. Reed's allowing them to stretch along with him, Sue's turns invisible along with her skin, and Johnny's is fireproof. These would prove quickly indispensable, due to the fact the Fantastic Four's more dangerous powers (such as Johnny's) constantly destroyed their normal clothing. They would begin to always wear the skintight suits under other clothes.
Reed Richards later learnt that the synthetics in the uniform adapted to their needs, so he adapted the designs and produced a uniform for each member of the team. Ben Grimm, however, was unable to wear the uniform due to his increase in size and mass, so only wore half of the uniform.
The team wear the same uniform as before. Also Johnny Storm endorses a new uniform with a lot of promotions by leading retailers. However, none were taken on, subsequently never producing or using the uniform.
