When you think superheroes you think Captain America! Batman! Wolverine! Spider-Man! Likewise, when you think of superhero weapons you think of Cap's shield, Batman's whole array of awesome gadgets (Batarangs, grappling guns, etc.), or Wolverine's claws and Spidey's webshooters. Well... for every Spider-Man there's a Booster Gold; for every Mjolnir there's a Boxing-Glove-Arrow.
Sometimes something will sound good in the pitch meeting, or seem super useful, iconic, and cool... but it just does not translate on the page. Out of context, Green Goblin's pumpkin bombs might seem silly and ridiculous, but with the right writer and artist those things are terrifying. We imagine that before it was on the page Goblin's Electrically Charged Frogs seemed like a good idea but... well... they are certainly not Pumpkin Bombs...These are those other weapons, those preposterous creations that grace the pages of our favorite books and make us scratch our heads, wondering how they got there. These are the lamest weapons in comics!
Fake Cat Arrow
We could have made an entire list out of Hawkeye and Green Arrow's ridiculous "trick" arrows. This arrow is a DUMMY CAT?! That he shoots through the air in order to make a meowing sound and distract his foes?What? Why? How? Where does it go?!
