We saw the toys, we hear the words coming from various people that these suits were designed by PLEX, the ones responsible for most Super Sentai and Kamen Rider suits and now, it is confirmed, these Mega Ranger suits will be part of Power Rangers Samurai!
Rangerboard's TheNewGuy posted this regarding the said suits:
From the ManufacturerNew theme in 2011 – Power Rangers Samurai. Each articulated figure has a New sleek MegaMode style, as seen in the TV series, making these Samurai Rangers stand out from the rest of the pack. The Rangers include a Mega Sword and special unique weapon making the rangers ready to battle. Crafted with great detail and quality, collectors and kids can play or display their favorite Power Ranger in their own environment and recreate scenes from the TV show.
This isn't the first time we saw an original power-up for Power Rangers, since Power Rangers in Space, the Battlizer is being used in the series which was later imported for the Dekaranger vs. Magiranger crossover film.
