Ridley (Metroid)
Throughout the history of the "Metroid" series, Ridley has received positive reception as the series antagonist. He is widely considered one of the most renowned and best Nintendo villains of all time and is regarded as a favorite amongst both the "Metroid" fandom and the series's developers. Nintendo Power listed him as their sixth favorite Nintendo villain, citing both his involvement in the death of Samus's parents as well as his determination, dying at Samus' hands many times yet always coming back. Computer and Video Games editor Mike Jackson described Ridley as a "fan favorite." GameDaily called him the 16th greatest Nintendo character, commenting that he "beats Mother Brain by a mile as the coolest Metroid villain." IGN editor Jesse Schedeen called Ridley the real villain of the "Metroid" series, commenting that he would have to be included in a "Metroid" film if one were made due to him being too important to leave out. 1UP.com editor Nadia Oxford described the Nintendo Comics System version of Ridley as being more of a "squashed bug" than a "fearsome reptile." WatchMojo.com ranked Ridley at #3 in their Top 10 Nintendo Villains list. The 1UP.com staff listed the battle with Ridley in "Super Metroid" as among the most iconic in Nintendo history. They stated that his appearance in "Super Metroid" is more memorable than any other appearance in the "Metroid" series, and that his return from the original game added some familiarity to "Metroid" fans. GamesRadar listed him third on their list of video game villains who will never stay dead, calling him Samus's "great white whale" that, even while he has tormented her throughout her life, she just cannot seem to kill. Gaming Nexus criticized the lack of fellow "Metroid" villain Kraid in "", but stated that the developers made up for it by adding the best Ridley battle in the series's history. IGN editors Phil Pirrello and Richard George listed Ridley as the second most deserving Nintendo character for inclusion in "Super Smash Bros. Brawl", stating that Samus was the only playable character in the game to represent the "Metroid" series (despite it being one of Nintendo's most famous and revered), and that the inclusion of Ridley would broaden the series's range. Overall, he is seen as one of the best Nintendo characters in general. In 2018, Watchmojo.com ranked him #1 on their "Top 10 Most Anticipated New Characters In Smash Ultimate" list.
Ridley (Metroid)
Throughout the series, Ridley has undergone a variety of changes in appearance. In the original "Metroid" title, he was roughly the same size as protagonist Samus Aran and sported a more alien appearance (particularly in official artwork, which depicted him with eight eyes running down the length of his head and a small, lamprey-like mouth). In "Super Metroid", he is larger than in the original title several times over, sporting purplish-brown skin, glowing yellow eyes, chameleonic abilities (possibly explaining his inconsistent skin tone across different games and even within different parts of "Super Metroid"), and an overall body shape that heavily resembles a European dragon. Later games depict him as larger still, and "Other M" departs from previous depictions by giving him a bulky, muscular form in contrast with his skeletal appearance in previous games, along with completely purple skin and flattened jaws resembling a pointed duck bill with a noticeable underbite. Ridley's vocalizations were first depicted in "Super Metroid" and took the form of a predatory screech; later 2D titles instead gave him piercing, high-pitched wails, while 3D installments such as the "Prime" games and "Other M" had him perform monstrous roars. His cybernetic form during the events of the "Prime" series is referred to as Meta Ridley and incorporates various ballistic weapon systems, while a robotic duplicate, Ridley Robot, appears as the final boss in "Zero Mission". While he did not originally appear in "", in the 3DS remake "", Ridley returns as the game's final boss in a new cybernetic form called Proteus Ridley in an attempt to steal the last living Metroid before Samus can deliver it to the Galactic Federation, though he is defeated once more. In the new title of the "Super Smash Bros." series, "Super Smash Bros. Ultimate", he is shown as he was in "Super Metroid", with a darker, purplish tone to his skin and with a size scaled to his original appearance in the first Metroid title, although he has an alternate costume resembling Meta Ridley.
