|Galvan Prime, or Galvan Mark II|
|First Appearance||War of the Worlds: Part 1|
Galvan Prime, or Galvan Mark II is the home planet of the Galvans.
From space, Galvan Prime is a pale green world with what looks like a giant crater with a large dark green area around it. Galvan Prime is one of the most scientifically advanced worlds in the galaxy. Miniature skyscrapers and ultra-fast causeways litter the landscape, thus leaving little room for nature.
