NAXA

NAXA, known as ANSA in Japan, is a space administration that was introduced in Mega Man Battle Network 4. The cooperation has incredibly high-tech astronomical equipment and is the head of space research. It is essentially the Mega Man Battle Network series equivalent of NASA (National Aeronautics and Space Administration).

In the two centuries between the Mega Man Battle Network and Mega Man Star Force series, NAXA appears to have become (or succeeded by) WAZA.

In the games
The opening scene of Mega Man Battle Network 4 takes place in NAXA. Working scientists suddenly discover that radars have picked up a large object heading towards Earth.
