Later, Guardian attacked Knuckles the Echidna while he was about to enter the Sandopolis Zone pyramid. As before, however, it fell into a quicksand pit, probably destroying it for good.
Powers and abilities
Despite its colossal size, the Guardian can make very high jumps that rival Sonic's. It is practically indestructible.
The Guardian's only weak point appears to be its head; upon hitting it, the golem will temporarily cover itself in a ball, making it look like it received a great pain. It is also extremely slow, takes a long time to jump and does not seem to know how to walk.
Once the player reaches the end of Sandopolis Zone Act 1, they will fall into a pit, in which a pyramid will "rise" to the sandstone. After about thirty seconds, the door to the pyramid will open, the Guardian will exit, and the battle will begin.
The battle will be long and boring since Guardian will only follow the player by jumping towards it. The playable character can hit its head, which will push it to the opposite side. To win, the player must have Guardian jump into a quicksand pit on the left side of the field. This can be done by placing it on the edge of the well and hitting its head behind it to throw it, or by making it jump alone into the well by getting into it (this alternative is a bit risky though).
Once it falls into the well, it will be destroyed, and a Goal Plate will fall to end the Act.
A Guardian was awoken when Captain Plunder raised the lost pyramid. Since they could not beat it, Knuckles instead lured it into some quicksand. Another was activated by Nack the Weasel and used against Knuckles and the Chaotix Crew, but the group beat it by shrinking it down to a manageable size.
The spinning Goal Post does not drop down at the location of the sub-boss when it was defeated (because this would cause the Goal Plate to land in the quicksand pit). Instead, it drops at a set point on solid land (but can still be knocked into the quicksand pit if the player hits it before it lands).
Additionally, the boss music doesn't end until the Goal Plate lands on the ground and Sonic/Tails/Knuckles perform their victory pose (unlike other bosses whose music ends after dealing the final hit).
Super Tails can make this boss encounter a nuisance, as the Flickies can constantly attack the Guardian, thus preventing it from jumping toward the quicksand as needed. This can be circumvented by simply not activating the transformation or just eventually running out of Rings.
