“SS design. Mix between Sheik’s agility and Zelda’s magic.”
The first thing that comes to mind is the strangeness of using her Skyward Sword design when, save for Toon Link, all of the Zelda characters use Twilight Princess inspired designs. Skyward Sword was a big hit for Nintendo, and the biggest Zelda release since Brawl, so it’s certainly conceivable that it could get roster representation, especially with a character who has relevance to the series beyond that game. However, Impa has ridiculous proportions, making her design clash strongly with the other Zelda characters. Sakurai has clearly tried to implement a consistent art style for each series, Toon Link being the one and only exception, and this version of Impa would throw a big wrench in that. It could be an updated design with less exaggerated proportions, similar to how Sheik’s design was updated for Brawl, but that seems like more of a stretch.
The second suspicious thing is that Impa has by far the most vague and least detailed description of the five characters, and it’s hard to really say from this whether she’s a Sheik clone, a Zelda clone, a mix of both, or an entirely original character. Some have said that given that the transformation characters have been split up, a new character that bridges Zelda and Sheik’s play styles makes sense, and the potential of a move set that combines the best of the two is vast. I would assume that Impa is at least a semi-clone, like Dixie. Five characters with entirely original move sets seems like too much to hold back for the Wii U, three original characters and two clones seems a little more reasonable. Given the similarities between her and Sheik, Impa is a reasonable character to make a clone, unlike say, Ganondorf.
For Impa:
-Most plausible Zelda Newcomer that’s not already an AT
Tingle, Skull Kid, Midna, Ghirahim. All highly requested at one point or another, all Assist Trophies. Not only has Impa yet to appear in AT form, but she also has seniority on every Zelda character that isn’t already playable, debuting in the instruction manual for the original legend of Zelda, and appearing quite frequently since as the most frequently reoccurring character that isn’t named Link, Zelda, or Ganon (although Tingle is close). She certainly has enough historical importance to the series to deserve a roster spot, and has made several prominent appearances since Brawl in Skyward Sword, A Link Between Worlds, and Hyrule Warriors, putting her in a similar position as newcomers like Rosalina and Bowser Jr. While I would have personally preferred Tingle, she would be a very solid pick for a Zelda Newcomer, and adds yet another playable female character to a roster where Sakurai has made that a clear priority.
-No trophy for SS design on 3DS
Only Impa’s Ocarina of Time design appears as a trophy on 3DS, so if her Skyward Sword design is in fact the one being used, her 3DS trophy could just be an extra trophy like the ones many other playable characters have.
Against Impa:
-Not mentioned by Spainkiller
While the Spainkiller leak is only moderately more credible than this one, it always helps to have multiple sources naming a particular character, and it’s highly suspicious that all four of the other characters were mentioned by Spainkiller except for Impa. It could be that Spainkiller’s source simply hadn’t seen Impa yet, or it could be that the ToS leaker is full of it.
-Mentioned by known liar Mother****ing Leaker, ToS leaker may be piggy backing
Impa, alongside Ridley, Mewtwo, Dixie, and Mach Rider, was mentioned as one of the “Final Five” by Mother****ing Leaker, the 4chan poster who leaked the ESRB photos. Prior to this, fake leaks rarely if ever mentioned Impa, and after the disconfirmation of Ghirahim, most people had decided that there would be no Zelda newcomer. However, Mother****ing Leaker has admitted to lying about other things, and it’s very possible that Impa’s inclusion in this leak is piggybacking off of Mother****ing leaker, leaving out the more out-there suggestion of Mach Rider in order to be more credible.
-Oot Design trophy on 3DS
It could easily be the case that Impa is no more than a trophy, but gets a Skyward Sword trophy on Wii U and an OoT 3D one on 3DS.
