Because there is no outfit for Spike in SFM that would make him look like Link.



And call me stupid, but I also can't think of how Spike would be a more fitting character. Yes, Sunset isn't the most obvious choice, but neither is Spike to me. He's a dragon, implying fire, therefore implying Goron. If you know of anyting that would make Spike more fitting, tell me, I'm willing to know, but the only correlations I can think of between Spike and Link is that he's young (like Young Link in OoT) and that he's bipedal, so he can use his hands (claws?) for items.



But hey, what do I know ¯\_(ツ)_/¯



*tbh I only used Sunset for these pictures because she's the most common in my pics in general, rip
