Base Mortar

BaseMortar, known as "Vulcana" (バルカナ) in Japan, is an EM Virus from Mega Man Star Force 2 that acts similar to the Cannonbase. Instead of firing a large bomb, the BaseMortar fires a series of projectiles in rapid succession.

Battle Cards
Viruses from the BaseMortar family drop Battle Cards from the Mad Vulcan (マッドバルカン) family. Those cards hit targets multiple times, each successful hit causing 10 damage.
