Assist Trophy rumor
On October 17, 2010, SSF2 Developer Ramsey posted a fake screenshot of Luffy using his Gomu Gomu no Baku Baku (ゴムゴムのバクバク, "Rubber Rubber Chomp Chomp") against Ness, leading fans to assume that he (Luffy) would appear as an Assist Trophy in version 0.7 of the Super Smash Flash 2 Demo (which he did not appear in.) It has since been confirmed that Luffy will be an Expansion Character and has already been coded as such.
