The Chosen One: In the movie, turns out Rikochet is the Chosen One that must defeat the evil El Maléfico to save the Earth. Somewhat averted in that they only win by he, Buena Girl, and the Flea working together. He doesn't even get the finishing blow.
Fun with Flushing: Rikochet, Buena Girl and the Flea fight a masked toilet twice in the series. Also, The Flea swims in a toilet at one point.
Good Angel, Bad Angel: Buena Girl and The Flea appear as Rikochet's angel and devil, respectively, in "Honor Thy Lucha". At the end, The Flea is convinced by two devils to melt the ice caps.
A later subversion has The Flea with a devil and an angel, but in this dilemma (in which The Flea has an unfair advantage because Rikochet is in very bad shape), the angel actually agrees with the devil.
Gosh Hornet: In the camp episode, when Buena Girl shoots a beehive during archery practice and they attack her.
Sealed Evil in a Can: El Maléfico was sealed away in the bowels of the Earth for 100,000 years. Flea sets him loose by reading a sentence from the Code of Masked Wrestling backwards. In the end, he gets put back in his can.
