Japanese gaming publication Nintendo Dream has shared some concept art from Sonic Frontiers in the October 2026 edition of the magazine. The concept art showcases various designs for Sage and also Koco’s shift from plant beings to mystical stone figures which were apparently inspired by clay bells. Check out the early Sonic Frontiers concept art down below.
Early Sonic Frontiers concept art reveals Sage and Koco evolution





One of the Sage character beta designs from sonic frontiers reminds me of Rin Kaga from Bunny Drop.
Nice
Is it bad to say I prefer the concept art Sage designs over what we have now? Oh and find my pages
some these koco’s looks kinda scary
I like Sage, scratch that, LOVE Sage. But this concept art, it just makes me think these are all the different designs Eggman went through before settling on her actual design. (Lore Wise)
I love Sage dress with a ponytail style in that concept.
