YMMV / Justice League Heroes

• Camera Screw: On the free-roaming levels, the camera is constantly swinging to follow behind your controlled character. Swing speed can be adjusted in options, but it doesn't make the game any less disorienting.
• Complete Monster:
  • Brainiac, after receiving a telepathic message from a meteorite, promising him great power and knowledge if he can release the power within the meteor, launches a complex scheme to get the equipment he needs. He creates a series of disasters to keep the Justice League busy: He has his robot minions attack random citizens; has Queen Bee transform people into bee creatures; hires the Key and Killer Frost to set off several nuclear weapons; frees the White Martians so they can attack Earth; frees Gorilla Grodd so he will use his Earthquake Machine, eventually planning to destroy Gorilla City; and uses a Doomsday clone to help him take over the Justice League Watchtower, imprison Martian Manhunter, and steal a Mother Box. Brainiac is willing to endanger millions of lives just as a distraction tactic, so the Justice League would too busy to stop his quest for power and knowledge.
  • Darkseid himself, while trapped inside an extradimensional prison, had been manipulating Brainiac the whole time, communicating telepathically via the meteorite. He makes his actual appearance by vaporizing Brainiac. Darkseid then uses the Mother Box and a Sensory Matrix Field Generator to banish the Justice League, before transforming the Earth into a new Apokolips, which he describes as "something far, far worse'' than Hell on Earth; he then incarcerates Superman in a Kryptonite prison.
  • Justice League Heroes: The Flash spinoff: Brainiac is once again portrayed as a sociopathic robot with zero redeeming qualities. Having set his sights on freeing a presence within a meteor in exchange for knowledge and power, he allows Gorilla Grodd to wreak havoc in Keystone; sends Killer Frost to destroy Gotham; sends Circe to take over and, eventually, destroy Themyscira; and gives Zoom the means to destroy the Pacific Coast, which will flood Coast City in order to distract the Justice League from his plans. After all his subordinates are defeated, Brainiac personally invades Metropolis and, when confronted by Flash, reveals that he has triggered the bomb that will atomize Metropolis.
• Game-Breaker: Zatanna can make the combat extremely easy by turning enemies into harmless bunnies and her heal spell can instantly recover her and the AI partner's health and with the right upgrades and builds, it can be cast at full strength with minimal cost.
• Hilarious in Hindsight: Crispin Freeman voices Superman here. Two years later his real life sister goes on to play one of his enemies.
• Underused Game Mechanic: Being allowed to choose party members is not very common and only becomes available in the second half of the game.
