Gamescom Opening Night Live is taking place soon, and ahead of the showcase hosted by Geoff Keighley, Sega has been hyping up a new Sonic Frontiers trailer that will be airing at the event.

Now, in another new screenshot, fans have been formally introduced to Koco - a "lil" creature that will likely feature throughout Sonic's new "open-zone" adventure. We've previously seen whatever these characters are in IGN's "world premiere" gameplay trailer.

The introduction of this character via the official Sonic the Hedgehog Twitter account has raised all sorts of responses. Some common ones seem to be asking for Chao to come back, while other Sonic fans have made reference to Zelda's Korok, and even Kodama tree spirits from Japanese folklore.

In Nintendo's open-world Zelda game, Breath of the Wild, Link is required to search the entire game's map for Korok high and low. It's unclear at this stage exactly what role "Koco" will play in Sonic Frontiers.

What do you think of this new character? Looking forward to the new Sonic Frontiers "world premiere" taking place at ONL? Tell us down below.
