This weekend as part of their celebration of the franchise’s 20th anniversary, Square Enix announced Kingdom Hearts 4, an Unreal Engine 5 soft reboot of the series that promises to start a whole new story arc. The first Kingdom Hearts 4 trailer showed off a lot of interesting stuff, including a fresh look for Sora, a more serious, realistic tone and visual style, and a new open world, but there weren’t a lot of explicit teases about what Disney crossovers and cameos we can expect this time (presumably, that’s still the point of this series).

That said, there was at least one juicy hint – at around the 4:40 mark in the new trailer, we see multiple shots of a mysterious forest, and if you look closely, you’ll catch what looks to be a “foot” of an Imperial walker in the background. Perhaps an AT-ST or even AT-AT (the former would be more of a fit for the leafy Endor-like environment).
