Perplexahedron Guards

The Perplexahedron Guards are first to appear in episode Perplexahedron. In this episode They are battled various times by the team, but confirmed to only show up once getting closer to the Map of Infinity piece and are meant to eliminate anyone who gets close to it. They also don't appear to speak.

Abilities
Perplexahedron Guards are robots meant to protect the final piece of the Map of Infinity. When getting closer to the Map of Infinity they shape-shift from a door into a body and begin to fight the encounter. They are shown to have a few abilities such as enhanced strength and shooting laser beams out of their hands.

Appearance
The Perplexahedron's Guards appear to be large white humanoid robots with no facial features (no nose, mouth, etc). They resemble the body of a large male and appear to be quite built. They sort of resemble Alien X without the the three horns and green eyes.
