He's got the most lines for any single villain, because he's so popular! Or was that unpopular? Either way, he's CHATTY!

In this timeline, Legacy and Baron Blade have long fought each other, the heroic Paul Parsons constantly thwarting the villainous plans of the dastardly Baron Blade. Legacy's daughter, Pauline Felicia Parsons, grew up knowing that her father was a hero, that he fought crime, and that his life was in constant danger. The weight of the Parsons family line was clear: where evil reared its ugly head, there would always be a Legacy there to stop it.

When she reached 18 years old, Felicia was given a Legacy costume by her parents, and her father began training her in earnest. Her whole life had been dedicated to the pursuit of justice and preparing herself for the inevitable combat against evil, and she took to this new training like a champion. The years of crime-fighting with the Freedom Five were hard work, but some of the best years of her life.

Years later, Felicia Parsons was the best prepared to accept her father's death at the hands of Baron Blade.

The countless heroes who had fought alongside Legacy were stunned. No one could accept that it could happen. But Felicia calmly organized a lovely funeral for her father, and then smoothly stepped into his place in the Freedom Five - she had prepared her whole life for this, and she was ready to wear this mantle. No one saw the few tears she shed in silence for her father.

As awful as the death of Legacy was, an alternate timeline experienced an even more terrible event.

In that same fateful battle, the mad Baron cornered and murdered the young Felicia Parsons, America's Newest Legacy, which left Paul Parsons America's Final Legacy. Legacy did not handle this well at all. He flew into a blind fury, tearing Baron Blade and the Wagner Mars Base apart.

Enraged and grief-stricken, Legacy disappeared. At Pauline Felicia Parson's funeral, little was said. The collected anguish of the mourners was far too great. Paul Parsons had not been heard from and did not attend the funeral, though some claimed to see a figure land in the graveyard later that night.

When Paul Parsons reappeared, it was in a very different form than before. The same strength and power was evident, but the man formerly called America's Finest Legacy was overcome with despair both for his family and for the future of mankind. His choice was clear: after him, there would be no Legacy. The world must be purged of all evil while he could still fight.

Paul Parsons patrolled the world, silencing those who stood in his way swiftly and brutally. No longer the confident leader of the Freedom Five, he took to wearing armor and to destroying any suspected evildoers without pause or question. All of the strength and fortitude of the hero Legacy was now channeled into an unbending global dictatorship. Called Iron Legacy by his former allies, he reshaped the world into one which shook beneath his iron fist.

The heroes of the world came together to attempt to talk sense into the man who had inspired so many of them, but any who attempted to stop him were silenced without remorse. The toll was staggering. The world's foremost hero was now the greatest threat to freedom and liberty, all in the name of justice.

Now, with the timelines in disarray and so many worlds and realities intersecting, Iron Legacy has a chance to spread his rule even further. Will the heroes be able to stop him? Can they even bring themselves to fight? Iron Legacy has no such compunctions. His will is iron. Justice will be done. Do not stand in his way.

You were never really a hero, Frost. Stop pretending and submit to justice.    You were always the best of us. What could have driven you to such madness?

Of all people, you should understand my position, Frost. No second chances for the scum who wreck lives!    You may be Paul, but you aren't Legacy. You're just a bitter, twisted thing that needs to be put on ice.

You have faced me before and failed, Zero. Live up to your name. Give up now.    That's cold boss. Bad news: I'm not so easily frightened. Let's do this.

I've taken down you and your allies before. Your ice cannot withstand the might of iron!    You couldn't take me out in your messed up future, and I'm at least as cool as that guy!

Be a good soldier and lay down your weapons, Vance. You know better than to stand in the way of justice.    I cannot believe that you are the same man. You're getting the whole payload, you monster.

Out of my way, Vance! Nothing in that suit is going to stop justice.    Focus on the mission and remember that he won't hold back. Good luck, everyone. This is it.

villain such as you, claiming to be a hero? You will be brought to justice!    Justice? You've a one track mind, Legacy. Too bad this is your stop.

I only know you from photographs, but even displaced from time, you are not above the Iron Law!    You and I are from different times, but all that ends here. Lock and load, team!

So much promise, Lieutenant Vance. Too bad you've squandered it all - now you must pay!    You're not the hero I signed up to work with. But you'll soon see what I've learned from him.

I was like you once. An innocent fool. The world is not as good as you think it is.    The world deserves protecting! A few bad eggs can't condemn the entire planet!

You may not approve, father, but I am finishing the work of all Legacies.    No Paul Parsons would ever stoop to such levels! Remember your father's legacy!

I saw you die. You're no daughter of mine. Stand down, Imposter.    I don't know who you are, but my father would never act like this. You're going down.

I cannot allow people continue to suffer injustice. They must learn there are consequences if they stray from the right path.    If you call this bringing justice to people, then my place is between you and them.

Blade! My legacy will end with me, but yours has already ended!    And they call me mad. Some legacies must end. We shall see who perseveres this day.

I don't care if you're a clone, a robot, or some other trick. All with the name Ramonat must fall!    You lack the mad mirth of the Legacy of Destruction. Your legacy is of sorry and loss. I cannot let your sadness crush this world as well.

 My old allies have turned against me? They too must be punished swiftly.    Whoa there, Paul. You've gone off your proverbial rocker! Time has not treated you well.

Run all you want, would-be-insurgent. I only need one good hit to put you down.    A long, drawn out fight plays to your strengths, you false Legacy. Gottatakeyououtquick!

You call yourself a leader? Can you slow down enough to see your own impending loss?    You're the one who can't see the obvious right in front of him. Enough, legacy.

Dr. Stinson, your hypotheses are no longer necessary. The absolute truth is that of justice!    I'd need to do some experiments to be certain, but you are barely the legacy I know.

How could an alien from another planet even understand true justice? Begone, transient.    Your face is that of my friend, but your actions are that of a tyrant! I know tyranny all to well…

You come from some distant planet and think to change this world? You have no place here.    I have found my place among your former allies. Your reign of terror must end now!

You are not the Tempest I have already defeated, but you will face the same fate!    This time is not yours - I know the true Paul Parsons, and your way is far from his.

I see the skies have darkened, alien. You mean to stand in my way? So be it.    This storm is of your making, Paul Parsons. Now reap the whirlwind of your Legacy!

Cease with your childish prattlings! You and your mechanical minions shall submit to justice!    Mr. Parsons, you've always been nice. I hate to make robots hit you, but they will!

Robots are not people. You shall not face judgement. Instead, you face destruction!    Hey, I'm no robot. I'm a person… who happens to be made of metal! You're a meanie.

You've opposed me before, but you cannot hope to prevail in the face of iron justice!    I know you're not the real Legacy. He'd never do this. Still, I don’t like fighting you.

You should know the truth of the world, Montgomery. All evildoers get punished.    So, even you turn to darkness, given the opportunity. I fight for justice, as you once did.

I will show you what happens when your fear stops holding back.    I've faced the darkness inside myself. You allowed your darkness to break you. And others.

You have turned to darkness, The Wraith. Or should I call you "The Chairwoman" now?    Keep your pithy titles for your Iron Rule, Parsons. Your time has come.

Stop skulking in the shadows, Wraith! Stand forth and face justice!    This is not your time, nor is it your place. You should know better than to pick this fight.
