One of the Krazoa shrines in Star Fox Adventures, the Test of Fear, features the only in-game appearance of a mysterious dromeosaur-esque race known as the "ShadowHunters".

The ShadowHunters had a larger role in the original Dinosaur Planet. Krystal, accompanied with a LightFoot guide in place of Kyte (mirroring how Sabre was supposed to get a temporary sidekick in place of Tricky in the form of a infant RedEye within Walled City), would come across them in an area called BlackWater Canyon, which was said to be the dinosaur's sacred burial grounds, and the home of the Tree of Souls, which was said to return the magic energy of a dinosaur into the planet after their death. The ShadowHunter Tribe were the protectors of this place, with their leader being one of the SpellStone guardians, who agrees to give Krystal his SpellStone, only for his jealous son to run off with it, leading to Krystal and the LightFoot to chase after him. Eventually this leads to the ShadowHunter being trapped within the rib cages of a giant skeletal monster, which would act as the boss fight of BlackWater Canyon. After Krystal and the LightFoot defeated it, the ShadowHunter would realize that they were really trying to save Dinosaur Planet, and gave them the SpellStone, which would then be activated by the ShadowHunter leader.

BlackWater Canyon appears in the leaked December 2000 build of Dinosaur Planet, but is notably devoid of any actual design work or puzzles. The voice lines from the ShadowHunters found in this build seem to indicate a different story from what was presented in the Condensed Story; instead of a SpellStone guardian father with a jealous son, they're portrayed as brothers who live as scavengers in BlackWater Canyon, who come across the SpellStone and claim it as their own, only to come across Krystal as well as Kyte, who would accompany her to BlackWater Canyon in place of the alformentioned LightFoot tribe member. One of the ShadowHunters siblings is willing to hand over the SpellStone, but the other seems to run off with it, which leads to Krystal and Kyte chasing after him, which leads to them encountering a ghostly apparition of Kyte's mother, the Queen CloudRunner (who was killed by General Scales back in CloudRunner Fortress) who encourages them on and warns them about the angry spirits within the area, presumably referring the aforementioned skeleton monster boss (that does not appear anywhere in the leaked build). After they retrieve the SpellStone, they seem to use the Tree of Souls to activate it in place of a proper SpellStone guardian.

BlackWater Canyon would be removed entirely in the transition to Star Fox Adventures, but it seems that Rare still had substantial plans for the ShadowHunters, as an unused briefing from Peppy Hare says this:


Which seems to indicate that earlier on in SFA's development, Rare had considered having the ShadowHunters fill in the role intended for the HookClaw tribe (who had already been cut by the time of the December 2000 Dinosaur Planet build) as the secondary carnivorous antagonist of the Walled City. This of course was scrapped in the final game, where only the RedEye tribe is present.

The senior animator of Star Fox Adventures, Michael Cawood, had mentioned on his website that when animating the Test of Fear, his goal for it wasn't well defined, and he didn't have enough time or resources to request additional assets and thus had to improvise. Fortunately for him, he had access to a library of animations for the ShadowHunters that had originally been planned as enemies in the game but had never got around to being implemented past the animation stage, very likely referring to when they planned as enemies encountered in SFA's iteration of the Walled City.

Funny enough, despite having such a minimal role in the final game, the ShadowHunters were present in some of Star Fox Adventures' Japanese material, most notably on the boxart, oddly utilizing their original Dinosaur Planet renders (presumably because the GCN models were not given an official render, due to them being a last minute addition after initially being scrapped).
