Bygone Adventures: Episode 1 "Wild Side"

On Bygone Island, Shadow keeps to himself for a reason. Most consider him the most dangerous villain on the island, but to some he is their most trusted hero.

A rumor is spreading of black creatures in the jungle, who will hunt anything, including a mobian. These apex predators could become a serious threat to the village, so Sonic and his gang decide to go check it out. But what they find isn't what any of them expected.
