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.
Breather Boss: Dr. Ion is noticeably simpler than the rest of the bosses in the game, telegraphing every attack and failing to block.
Crowning Moment of Awesome: Pretty much the entire game is composed of these. Where on earth to begin... How about fighting a luchadore gorilla? Perhaps unleashing Fist of the North Star-type finishing moves on sentai midgets in Disneyland?
Crowning Music of Awesome: Again, pretty much all of it. Capcom CloverMasafumi Takada knows his business.
Crowning Moment of Funny: God power keeps mah pimp hand strong. Quite possibly the most awesome and hilarious line in music ever.
After meeting Azel, Gene asks Olivia about her being his fiancée which prompts her to tell Gene about Azel murdering their clan. He comforts her with a small hug as she cries and says he'll become a god to counter Azel becoming a demon. He then immediately asks what base Azel managed to get to.
The scene that happens when you defeat Elvis for the first time. And the second time. Not so much the third time.
How do you go about fighting a giant fly? Why, spin your finger until it gets dizzy!
Cultural joke: In Japan, it's believed that you can capture dragonflies by spinning your finger in front of its eyes to make it dizzy.
Excuse Plot: Even the characters joke about how ridiculous it is.
Good Bad Bug: It's possible to get the Great Sensei into a stun loop.
Memetic Mutation: The God Hand comic, quoted above, created by an imageboard regular based on his own experiences with the game, which spawned numerous imitations based on other games. God Hand itself also qualifies to an extent.
"Giant Enemy Crane"
Also, a quote from a review: "It's a game about punching people"
There are a few photoshops of characters from other games pulling out a God Reel.
The stage "It's A Trap!!"
Needs More Love: The series has pretty much been ignored by Capcom (probably because it bombed commercially) and they have yet to add Gene as a fighter in a Capcom vs. Whatever game (While other Clover characters Viewtiful Joe and Amaterasu have).
Scrappy Level: Level Five makes many players want to cry. Get past that and Level Seven's "The Flying Pyramid" will make you wish for Level Five again.
That One Boss: All of them can be, but Demon Elvis and the Mad Midget Five are especially painful.
And the Great Sensei. My God, he was a pain in the ass.
