Poly

, as named in Roly Poly's game's menu, is the main character of Roly Poly. He has appeared as an enemy in Skywire 1 & 2, as well as in Nitrome Must Die.

Roly Poly
Poly starts out in each level enclosed in a circular area, of which the player rotates to help him move to the finish line safely. If he makes contact with a hazard, he will tense up and fall off the screen. The hedgehog is also seen in the game menu, guiding the player through the options with a speech bubble atop of his head. It is unknown why Poly wants to roll past many obstacles seen in each level, and whether the levels are parts of his home.

Skywire 1 & 2
Poly appears as an enemy in Skywire 1 and Skywire 2. Poly appears as a robotic toy, being made of metal and having a wind on its back. It attacks by shooting out its Spikes, soon regenerating them. These Spikes move in the direction they were fired, not increasing in velocity.

Nitrome Must Die
Oddly enough, the Skywire Robot Poly appears in Nitrome Must Die. While Poly appears early in the game, he is never the less quite dangerous. He is low down, making him harder to hit than most enemies and he shoots a multitude of small spikes all over the screen. However, he is quite slow and when knocked-out, explodes in a puddle of orange liquid, which is possibly molten metal or paint. They move horizontally on platforms, and turn at ledges. They are quite small, and the spikes deal little damage.

Trivia

 * Poly appears coming out of the ground, much like a zombie, in the Nitrome Horror skin.
 * He may be based of SEGA's Sonic the Hedgehog.
