Giant Enemy Crab
Origin: Genji: Days of the Blade
For all the spectacle put into the announcement of the PlayStation 3, Sony's 2006 E3 keynote was an outright embarrassment.
With honorable mentions for worst on stage quote of all-time laced through the presentation, things took a dramatic turn for the worse when a representative declared their new game, Genji: Days of the Blade was based on real battles of feudal Japanese history before unveiling a giant enemy crab that needed to be flipped over and attacked for MASSIVE DAMAGE.
Naturally, this became a joke online and is still repeated to this day.
