Each of the evil rings has malevolent faces on them, in contrast to the more element-themed Planeteer rings. Captain Pollution is weakened when he is in contact with pure elements such as clean water or sunlight, while he gains power from contact with pollutants, being able to absorb pollutant and emit radioactive rays (and is later shown to gain limitless power when in contact with pollutants after his resurrection). When he is summoned he says "By your polluting powers combined, I am Captain Pollution! Ha! Ha! Ha! Ha! Ha! Ha!", and when he disappears, he declares "The polluting power is yours!"
