I don't want Shadow mainly because he represents where the sonic series went bad, has a 2edgy4u personality, and was created to appeal to angsty teens on deviantart. He's almost as bad as the ORIGINAL CHARACTER, DONUT STEEL! characters.
The only character that I can think of that's as bad as him is Krystal.
Okay. It is time everyone stopped with the petty bad jokes and over exaggerated claims of how terrible Shadow is or any Sonic character for that matter. I'm going to start by disarming everyone's hostility towards where the series went bad. Shadow is a common scapegoat used to place the blame of the series decline.
Yuji Naka, the series Creator, is responsible for the direction Shadow took. Around the time Shadow's game was being considered, Yuji Naka wanted to experiment with the series using Shadow. The results as you can tell were not impressive. It was around the beginning of Sonic 06's development that Yuji Naka left the Sonic Team. After this happened, the game had no direction at this point and all hell broke loose. Many of the development team members were either fired or quit because of a pointlessly unbearable workload. The remaining members said "screw it" at some point and that is what we ended up with.
Yuji, after leaving the series behind, went to make games for new companies who were just getting started. Ivy the Kiwi was one of the games he made with a random company. It was a flop. He also worked on a game called Rodea the Sky Soldier. It was perceived as a spiritual successor to NiGHTS. The game was finished and has yet to be released from its initial announcement years ago. Yuji's craving for want to do something "new" is ultimately his downfall. He left the Sonic series in a poor state with Shadow as a scapegoat for the series decline.
Now for these ridiculous dA and/or furry statements. Does ones age or preference immediately tie them to a negative stereotype? If so, that is discrimination. "Because ones taste and age" means nothing. Being a furry or a deviant artist (regardless of age) should not be used as a stereotype against anyone.
As far as the "Original the Edge-hog" comments go, Shadow is no more edgy than Mewtwo. Practically the same story told differently. Nearly identical personalities. It takes one bad movie or game to change that perspective? I don't think so. People still hold to the nostalgia of Mewtwo. Why should that case be any different from a Shadow fan? For that matter, why would that be the case for any character? Why specifically Shadow? If we are going to toss recolor comments around...Dark Samus, Masked Man, and Shadow Mario. Why on God's good Earth do people insult one "recolor" to justify their own? It is pathetic and obviously hypocritical.
For anyone wanting to come at me with the 3rd party argument, this is Project M. A mod. Not Nintendo. The presented 3rd party characters in the game are eligible candidates. Making that argument is pointless in any context. Why should we restrict ourselves from voting on it? It isn't like we will ever get the chance to see that character playable in any future installment of SSB. I rest my case.
