User blog:Sheikah warrior/Shadow in SSB4?

Me and my friend have been having a large-scale war over this topic. I personally believe that Shadow should NOT UNDER ANY CIRCUMSTANCES be in SSB4. I personally think that if ANY other Sonic character gets in, it should be Tails, or perhaps Knuckles. My friend, however, seems to think Shadow the epitome of Sonic. I VEHEMENTLY disagree. But, our arguments are getting us nowhere, so let's take it to the fans. What do you guys think. Shadow playable, YES? Or NO?
