Skull Fortress

Skull Fortress is a starter stage appearing in Super Smash Flash 2, first appearing at one of the SSF2 Mini-Trailers and finally playable in the demo version 0.9. It is Mega Man's home stage.

Layout
The stage is composed of a large number of pass-through platforms at the middle and solid terrain at the sides, with a gap below the platforms. It is a walk-off stage, making it effective for chaingrabs.

The background of the stage shows Wily's Castle. From time to time, a horde of various Mega Man enemies are shown leaving the castle, and soon appear on stage walking from one side to another, dealing damage to everyone in the way. It is effectively possible to be locked by the minions via unfortunate DI, making them a dangerous hazard.

Origin
Castle Wily is the common name used for Dr. Wily's several fortresses with a skull motif that appear as the final stages of most games from the original Mega Man series. However, not all of them have names. For example, in the first Mega Man game, Wily's base is called Dr. Wily's robot manufacturing plant, but was renamed Wily Castle in Mega Man Powered Up. They often have several hazards, mazes, strong enemies, a rematch against the Robot Masters, and a final fight against Wily inside one of his machines; like the Wily Machines and Wily Capsules.

As said before and hinted by the DOJO!!, SSF2's Castle Wily version takes its appearance from the game Mega Man 2, more specifically the first part of the castle. However, the appearance was partially updated to look more like the levels from Mega Man 7, which explains why DeluPipis appear instead of regular Pipis.

Music
The music of the stage is a remixed version of the "Wily Castle" theme from Mega Man 2 composed by SSF2 Developer 194. It was also used in SSF2 0.8 Mega Man mini dev blog.

Trivia

 * The way Wily's minions come out from the base is similar to how the Yellow Devil comes out in Super Smash Bros. for Nintendo 3DS/Wii U ' s stage counterpart, Wily Castle. This was just a coincidence, though.
