If I had to choose, I'd say ship. Although Cream is 6 and SEGA refuses to have her date Tails, I can still ship this. 2 years isn't a big difference, and I think it's cute, and way better than Tailsey. We know Cream is younger, but Zoey is probably years older. And it's better than shipping Cream with Sonic. Cream is a character who has been used more than Zoey and Cosmo, and was used recently in Sonic Speed Simulator, 2-1 weeks ago. Cream is still used, just not as common as everyone else, like Tails and Sonic. She's still a main character. Meanwhile, Cosmo isn't even canon. You can say that she is, but everyone knows she isn't. Sonic X season 3 is not canon to the Sonic plot, but that's why we have #SaveCosmo to make Cosmo canon. If you want to see Tailsmo, subscribe to the channel and sign the petition to see it return.
Art by LunaAzul788 on DA (I think?) themed off an episode of Sonic X I predict. Since I couldn't get any clear images of the episode scene I wanted off my school computer.
