Sonic fangames on M.U.G.E.N. stand out for their impressive number and variety of characters, going far beyond the official roster. The Sonic Battle HD project, for example, features a roster of over 30 playable characters . This colossal list includes:
- Canonical Characters and Transformations: From Sonic, Shadow, Silver, Knuckles and Tails in their classic, super and hyper forms , to less conventional characters like E-102 Gamma, Mephiles and Infinite .
- Characters from Other Media and “Fanon”: Sally Acorn (from the comics), Manic and Sonia (from the TV series), and Sticks (from Sonic Boom) are present .
- Original Community Creations and “EXEs”: The game also incorporates famous community characters such as Nazo, Seelkadoom and various “EXE” versions , which are terrifying and distorted versions of the original characters, popularized by creepypastas. A character like Sonic.EXE, for example, has a moveset that includes multiple dashes and teleports, with visual effects reminiscent of Dragon Ball .
Playstyle and Moveset
The gameplay is typically that of a traditional 2D fighting game, but the movesets are often inspired by anime and are quite elaborate.
- Complex Movesets: Characters like Sonic.EXE have abilities like teleportation, energy projection and manipulation of the air around them . Many characters have several forms (Base, Hyper, True) that alter their power and attack range .
- High Customization: The nature of M.U.G.E.N. allows each creator to define their character’s fighting style. This results in an experience where you can find everything from fighting styles more faithful to the official Sonic games to completely overpowered and unbalanced styles focused on fun and fanservice.
