In a recent video, Zullie the Witch noted a few key Elden Ring Runes details about these bears.
First, there was one in the Elden Ring beta, which could only be accessed out of bonds, that.
dropped a Dragon Heart. Since it was a bear and this doesn't happen in the base game, it was thought to be a placeholder asset. The code for these animals also treat them as nothing real special, simply calling them Rune Bears, but it is worth noting some of the plant enemies and the red wolves are called "RuneWolf" and so on in the code. And to cap it all off, Rune Bears have draconic eyes. Their standard counterparts do not obviously, but they are a match for the yellow eyes of the Elden Ring protagonist should players take part in Dragon Communion and for dragon eyes LOLGA.COM at that.
