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.
Moment Of Awesome: As Eel O'Brian. In one story where the members of the Justice League were separated into two halves, their "civilian" and "super" personas, Eel was the one who got the "civilian" team together, including having to knock some sense into Bruce Wayne by pistol-whipping him and chewing him out. And finally, when the chips were down against the superpowered forms, Eel rallied the troops to challenge the nigh-omnipotent villains. "Who Dares Stand Against Us?" "We do."
Nightmare Fuel: Not in the main continuity, but in The Dark Knight Strikes Again, Plastic Man's gone off the deep end after being in a compression chamber for a couple decades, and he doesn't limit himself when utilizing his powers. Batman is extremely cautious when approaching him and says something to the effect of "He could kill us all if we piss him off." His face and demeanor when he's released are quite jarring.
