Some more background
Ice Pick
Whether or not this particular hero crosses the line has been a subject since he began his work and continues because of those following in his footsteps. Neville Thornton, Ice Pick, was the first vigilante in the modern age of heroes to kill his foes rather than turn them over to the justice system. Some argue that he had no choice because Nordon City's system was so corrupt. Other's argue that he had no right play judge, jury, and executioner. The only sure thing is that Ice Pick didn't care what either side thought. A master detective, Ice Pick always felt sure he had the right man and even let them know he was coming for them. He earned his moniker because he never left a trace of evidence that he was behind the killing of these men. Soon any case with a lack of evidence became attributed to the man, so Ice Pick would anonymously leave evidence at newspapers about the men he was actually responsible for killing. It was with that information, and a healthy dose of creative license, told stories of Ice Picks feats, including The Clean Knife, Club Trio, and The Rhine Affair.
The Golden Age of Superpowers
These are heroes who were around at the dawn of an explosion of heroes with superpowers. Some have remained over time (those won't be covered here), but most have faded away. The varied in powers from the ridiculous to the downright frightening. The villains were often your typical crooks, gangsters, and killers and didn't have superpowers themselves. These heroes set the foundation for what would come after them. And though most may now be forgotten, their influence remains.
Mighty Mack
Ned Sanders had been kidnapped by a group of racketeers after he failed to pay up what they asked for. The crooks dumped him into the a lake just outside of Centinal City, thinking the man was as good as dead. But Ned came into contact with an ancient treasure that had been lost at see and worked its way inland to the lake. The treasure, a small jar once blessed by an ancient priest who claimed it would give the owner what they needed most, made Ned bulletproof, though he would still fall prey to sharp items, and gave him super-strength. Dressed as Mighty Mack, Ned cleaned up neighborhoods of racketeers and gangsters. His heroics made him well-loved in cases like Ten Dimes from a Dollar, Tuesday was Yesterday, and The Wind Chime Bandit.
Wire Rider
After being struck by lightning while on the phone, Stephen Holmes developed the ability to travel through telephone wires. A boxer by trade, Stephen used his ability to get the jump on criminals and take them down. Some of a short but memorable career is told in stories like The Spanish Widow, Three Drops of Rain, and Green Was Her Favorite Color.
Two-of-a-Kind
Twins Hal and Red Tillers got mixed up in some gambling debts but recognized the error of their ways. A strange spirit came to them offering a way out of their debts, but as repayment they would give their lives to fighting crime. They agreed and soon Two-of-a-Kind, heroes who magical decks of cards could be used as weapons, were born. Their foes really bought into the whole get up and soon the duo ran up against Full House, The River, and The Queen of Spades. Their odd and short-lived crime fighting career was recorded in stories such as Ante Up, Folded Too Late, and Texas Goes All-In.
