Huntik: Secrets & Seekers/YMMV

Awesome McCoolname: There's just something so cool about the name Dante Vale
Complete Monster: The Betrayer, originally one of the sorcerers and seekers who helped found the Huntik Foundation, turned upon his fellows to summon the Lovecraftians monstrosities known as the Nullifers to destroy the world. The Casterwill family fought back and destroyed the Betrayer, but his spirit endured, forming the Bloodspiral Brotherhood to work at his revival. The Betrayer eventually had the Casterwill family 'purged' with any who served as obstacles treated the same way. Upon his revival, the Betrayer revealed that he had double-crossed the Bloodspiral Brotherhood and they would not be spared from destruction either. The Betrayer proceeds to summon a comet the destroy everyone present and summon the Nullifers, plotting to destroy everything that lives on earth to satisfy his lust for chaos.
Crowning Music of Awesome: The show's theme song qualifies, doubling as an Ear Worm at that.
The Scrappy: One or two people may not like Cherit. Heck, it almost seems like Cherit is designed to be this, but despite his nails-on-blackboard voice and shrimpy appearance, he's actually pretty funny and likeable. Plus, y'know, lasers.
What an Idiot!: Zhalia reveals herself to be the mole of the Organization and beats the crap out of Lok and Sophie. She is about to finish them off, but instead she ties them down. Despite the plan to do it again when it's over, she didn't because 1) she's sided with them in the end and 2) Lok and Sophie manage to get out of this situation on their own.
