Seaside Hospital

The Seaside Hospital is a location from Mega Man Battle Network 3, a hospital found in Beach Street. Mamoru is treated in this hospital, and Lan met him when Yai Ayanokoji got hurt during the N1 Grand Prix semi finals. The hospital was later attacked by Anetta and PlantMan.

There is a giant tree named the "Tree of Life" (イノシの木) in the center of the building that is sustained by machinery in the basement. Yuichiro Hikari was treated here after a fire accident caused by Mr. Match in Scilab.

The hospital has three floors, a beach front, and is run by high powered computers.

Tree of Life in the roof.

  • The Tree of Life is said to go out through the hospital's roof, and although it is present in the map from Perfect Navigation books, it is not present in the game itself, probably due to being impossible to see the roof by normal means.
  • Despite the similar name, there is no known affiliation with Seaside Hospital with the Seaside Town.
  • The Green Town from Mega Man Battle Network 6 also has a giant tree.
