>>23264897>Why not 4?In universe, I don't know since I haven't started GQuuuuuux yet but the Dom here is a reimagining of the classic '79 design.
The third leg is its backpack which can be deployed as a third leg. Each leg has a hover system so I'm guessing the third improves mobility and stability.
When it's retracted as a backpack, it keeps the look of the old design.
I also prefer Armored Core designs. I just figured I'd bring up the Dom since Gundam mechs with more than two legs (especially available in HG form) aren't too common so the new Dom came to mind.
