Can You Get DLC for LEGO Batman 2 on Wii? No—Other Versions Have It

No, LEGO Batman 2: DC Super Heroes on Wii has no DLC. The Wii version was a standalone release; the console's limited online infrastructure didn't support downloadable content.

For additional content (characters, levels), consider the PlayStation 3, Xbox 360, or PC versions, which do offer DLC packs.
