Hm... a very possible idea. ^__^
And, something more on the "Anubis" thing--
How do you know it doesn't have a snout? Its head in the silhouette is titled, its snout migth be pinting downward. It's ears (Well, they look like ears, could be horns or something) resemble a jackal's and it looks like it has an egyptian headress on. XD; Plus, Anubis is the god of the dead, symbolizing mummification and so on, and is said to protect the tombs from graverobbers (inspired by how jackals seem to roam around the tombs, JSYK). So, why couldn't an Anubis-like pok?mon be protecting the tombs of legendaries sealed away by people? (I say people because of what the brallie translates to in the cave where you unlock the regi.)
