Basic Arena

The Basic Arena is the primary location where battles take place, however nowadays battles are usually brought all over the place to other sanctioned locations. Certain ones such as the VR Arena are hosted inside the arena as well. It has had several incarnations throughout the various seasons of User Battles, changing a little bit each time.

User Battles Season 1
In the first place, the arena was nothing more than a large sandpit, surrounded by high concrete walls and a gate on each of four sides. The sand was very uneven and it was generally just a really boring and generic arena, which did get the job done. Tatters introduced differing arenas pretty early on to combat the monotony of this single arena.

Current
The current appearance of the arena, altered in UltraDrive, is a much more flat, lush, grassy plain. The gates remain, and a cobblestone path leads inward from all four of them, meeting in a sort of plaza in the very center. Some flowers and whatnot have started growing around the very edges. What was once bare concrete walls now is a packed audience within stands, with Hyper's booth overlooking one end.

Trivia

 * This is one of the few arenas to have received a complete overhaul.
 * Although it is what the arena is built around, not many battles are held here anymore.
 * The crowd is made up of in-universe fans of the sport, the same ones that built Battle Town.
