Guardian Sphinx Boss

The Guardian Sphinx Boss was a boss that would have appeared in the cancelled Sega Saturn video game, Sonic X-treme. According to the concept artwork, it is about four time taller than Sonic the Hedgehog, making the boss possibly a side-view battle. Excluding that, nothing else is known about the boss, but it seems that it could be based off of Egg Golem from Sonic & Knuckles, or it could have gave inspiration to the next Egg Golem that appears in Sonic Adventure 2.
