These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Eternal Champions
Critical Research Failure: Trident fought with Capoeira centuries before it was developed. Rule of Cool might circumvent this, considering that most of the characters fight with styles they couldn't possibly have learned in their environment.
And there's that whole Burn the Witch! thing, which never happened during the Salem Witch Trials.
The manual mentions that the Eternal Champion himself trained the characters that didn't know how to fight; furthermore, in Slash's ending, it's mentioned that he uses a technique learned from Xavier. None of this explains why an Atlantean champion (who died to a cheat) would learn a completely new fighting style...
Ensemble Dark Horse: If the Senator ran in real life, he would win the popular vote by a landslide.
Game Breaker: Trident in the first game. Plasma bolt + Spinning Trident = half your health gone in an INSTANT.
Magnificent Bastard: Where to begin with the Dark Champion? He withheld contestants so that the Eternal Champion's contest could never be completed, upon entering said contest distorted it into a battle of ego and hatred to further weaken his brother, and will abduct any contestant who is unfortunate enough to get curb stomped by their opponent and finish them off himself by using their worst fear against them. Yikes!
That One Boss: The Eternal and Dark Champions. On top of that, losing to either of them yields an instant Game Over.
The Eternal Champion's shark form is the worst offender, despite the fact that the Dark Champion had an attack in most of his forms that made him invulnerable.
