YMMV / Code Lyoko: EG

• Base-Breaking Character: XANA, an awesome villain more competent than most or an overpowered Invincible Villain?
• Complete Monster:
  • XANA far surpasses his canon counterpart in sadism. Originally a multi-agent program created by Sombra, XANA gained sapience through the multiple Returns to the Past and rebelled against him to fulfill his ambitions of godhood in Lyoko and the real world. Trapped by Celestia in the supercomputer for a decade alongside Sombra's daughter Fluttershy, XANA regularly launches various attacks against her and her friends the Lyoko 7 upon being revived, not hesitating to target or torture innocents or the Lyoko 7's loved ones in the process. XANA uses various strategies, first attempting to kill Fluttershy to prevent the Lyoko 7 from stopping his attacks, then corrupting Rarity in order for her to join him willingly, then similarly corrupting Luna, before taking over Twilight's body and forcing her to watch as he uses it against her friends and finally create the Dazzlings in order for them to join the Lyoko 7, help them create an anti-XANA program, and taking it away from them when they need it the most. A raging storm of malice and spite beneath his polite, seductive behavior, XANA left the heroes traumatized even after their victory.
  • Damien Tirek, the head of the government agency Tartatus, initially wanted to use virtual worlds to Take Over the World in all but name. Attacking the Equalists and killing one of their members when they hack into governmental programs, Tirek and Tartatus forces Sombra Sandora to work on the project under the threat of killing his wife, making good on said threat when she convinces Sombra to rebel. Later on teaming up with XANA under the belief the latter will exterminate humanity, Tirek forces the captured Twilight Sparkle to come up with a lethal attack against her friend Rarity Dostoevskaia and to fight against her other friends under the threat of killing Celestia, only prevented from carrying out said threat by XANA. Upon learning that his abused and unwilling accomplice Starlight Glimmer works betrayed him, Tirek tortures her, promising to make the rest of her life a living hell. While a Composite Character of his original counterpart and Lowell Tyron, Tirek outclasses these two's villainy to such an extent he earns even Pinkie Pie's undying hatred and loathing.
• Magnificent Bastard: Sunset Shimmer, while a Composite Character of her original canon self and William Dunbar, eclipses them both in dastardly brilliance. Joining an hacktivist group in her youth, Sunset worked with it to hack into large corporations, driving one to bankruptcy and nearly giving the same fate to 12 of the biggest government-funded companies. On the run after the group was sold out to the police, Sunset hacked into wealthy people's bank accounts for a living. Recruited by the Lyoko 6 after proving her worth, Sunset proves to be an invaluable member of the team, an effective leader during Twilight Sparkle's absence, tricking XANA into revealing to her his IP address and thus his Replikas, figuring out XANA's modus operandi, using her own crush on one of the Dazzlings to keep an eye on them when they infiltrate the Lyoko 7, and sending a hidden mail containing the anti-XANA program to Twilight while tricking XANA into stealing a fake, securing his final defeat in the long run.
