Pictures of the 5 Main Rangers 4″ Figures have been released for sale in stores such as Wal-Mart, Target & Toys R Us. Right now there are a few available on Ebay but I would wait for them to be available in your nearest stores.
The above image shows the back card of the first wave of Megaforce Figures! Red, Black, Blue, Pink, Yellow Rangers and Robo Knight. The set also includes the WarStar Villain Vrak and the foot soldiers; Loogies! It looks like each figure will come with a Power Card of the Ranger you purchase!
So far there are only images of the 5 Main Rangers from Ebay, when more become available I will post them:
(thanks to @Razzle1337 for posting the images on Twitter)
There are currently no images of the packaging for Vrak or Robo Knight but when they become available I will post images!
Have you found these in your area yet?
