The Union is the meta-human team formed by the governing body of the European Union. Shortly after the Second Storm, the EU decided together to become one solid country, to better allow militaries to move and protect its citizens. Deciding that they needed their own meta-human protectors, the call went out for volunteers.
A few heroes stepped up to the bat, and the EU council decided on the line-up. Then the unbelievable happened, Raven moved to Paris. The team asked the reluctant hero to help out, and after some considerable persuading, the team was fully staffed.
