You're still the only person I've ever seen claim that Geno is as popular as ever within the Smash community.
DeviantArt isn't even a valid source, anyway. Search results on DA aren't an accurate way to judge this sort of thing, and I'll explain why.
- The results for "Geno Smash" wouldn't be 100% SSB4-related. Results from Brawl and earlier games will show up. The same goes for K. Rool.
- Results do not equal individuals. It's not "608 SSB4 Geno fans vs 525 SSB4 K. Rool fans", it's "608 submissions involving Geno in any Smash game vs 525 submissions involving K. Rool in any Smash game". What this means is, multiple submissions by the same person are counted individually. A good chunk of the submissions on both sides may be by the same couple of users.
We have actual data collected from various Smash-centered forums and sites that prove that K. Rool is the most wanted newcomer for SSB4. Geno, on the other hand, does not perform very well. Not only does he usually lose to Paper Mario (meaning he's not even the most popular character request from his own series of origin), but also routinely gets lower percentages than the likes of Shrek and Goku, two infamous troll characters.
Even another Geno supporter in the "Stupid character suggestions" thread acknowledged that his popularity is not quite on the level it used to be. I constantly see him brought up alongside Krystal as an example of a character who's popularity plummeted in between Brawl and SSB4.
