- Cargo Ship: Mystique Sonia and Yaksha, especially since someone has to tell her that they love her three times in a row to become a Yaksha in the first place.
- Complete Monster: Twin Masters is a malevolent entity who wishes to plunge the Hidden Kingdom into everlasting chaos. Originally a prince with aspirations of conquest, Twin Masters had since become a master of chaos energy, altering their plans to decimate the Hidden Kingdom and lord over the remains as a despot. Several of Twin Masters's plans are designed to cause massive damage, including forcing Oyster-Rahmas into draining the oceans; trying to revert all life to its prehistoric state; changing the course of an asteroid to crash into Hidden Kingdom; creating a chaotic storm with Mighty Ray's eyes; and, in the finale, absorbing all life energy into themselves as well as condemning their former minions to die alongside Hidden Kingdom. Forming a deep hatred for First Squad—Lin Chung in particular—Twin Masters corrupts Commander ApeTrully with their chaos energy and forces him to attack First Squad against his will. Drunk on their love for carnage and destruction, Twin Masters darkened the setting of an otherwise lighthearted show with their presence.
- Jerkass Woobie: Second Squad, especially Alpha Girl during "Turtle Cannon Competition II" She is forced to painfully take one for the team, and her team loses BECAUSE of it.
- Nightmare Fuel: See here.
- They Wasted a Perfectly Good Plot: High Roller turning First Squad into Animals.
- In the season 2 episode "Animals Inside" though, First Squad actually does get turned into animals as part of the plot (but without High Roller being involved in their transformation), so maybe the plot ended up being not-wasted after all.
- The Woobie: Chameleon Queen
YMMV / Hero: 108
