Eel O'Brian, abandoned by his criminal gang after being shot and exposed to the acid, wandered the streets as his new powers developed, frightening others and bringing the police and National Guard down on him as a dangerous monster. Eel was at first oblivous to the changes to his body, but after realizing that he was the monster everyone was going on about, he used his new abilities to escape his pursuers, but soon became so despondent over his new condition that he attempted suicide by jumping off a bridge.
Fortunately, he was interrupted by Woozy Winks, a former mental patient who was kicked out of an institution due to lack of funding (or as Woozy put it, "something called Reaganomics"😉, who desired nothing more than to return to the warm safety of a straitjacket and padded room. Eel and Woozy decided to work together and capitalize on Eel's new powers to make their fortunes (Eel wanting to get rich quick, Woozy just wanting his "old room" back), but couldn't decide whether there was more money in crime or crime-fighting, and resorted to flipping a coin to choose serving the law (though Woozy had his doubts early on). Eel, ending up with the name "Plastic Man" after a reporter misinterpreted his first choice, "Elastic Man", and Woozy set up a detective agency in New York City and had various misadventures.
The alteration that Plas was initially in the superhero business for the money has had an effect on his character development post-Crisis, notably in a JLA storyline by Mark Waid where he, along with other Justice League members, was separated into two people, his normal "civilian" identity and his superhero persona. While Plastic Man devolved from a person with a sense of humor into a constantly wisecracking and almost ineffectual idiot, the now "normal" Eel O'Brian struggled with the criminal tendencies he had suppressed as he had become comfortable with his role as a superhero, and wondered if he had actually changed for the better or if it had all been part of the super-hero "act". Ultimately, Eel was the driving force behind the other transformed Leaguers banding together to re-join with their superheroic selves.
Durability
Bullets bounce off of him
Survives a massive explosion to no harm
Takes a punch from Shaggy Man
Steel's hammer is thrown quite a ways into Eel. The hammer does more damage the farther it's thrown.
It's basically ineffectual.
Talks casually about how some Flashes gave him a "molecular rubdown" to turn him from stone to molten lava, and about how he had molecular control in that form.
Circe fails to transform him, Plastic Man has very high resistance to transformation.
Uses his body to contain an exploding man.
Durability
Recovers pretty quickly from being hit with a gas attack (though, as Plastic Man's physiology is made of the same time of cell repeated and he lacks organs or inner functions, how this affected him is unclear)
He was nearly melted immediately prior to this by a magical fire.
Here he's back together again already, and ready to go. (The building was just asploded, iirc, hence the GL shield)
Huntress has no idea how to take him down.
Alien entities still haven't fully identified Plastic Man's physiology by the time it took them to identify the cellular makeup and power source of the entire JLA.
Operates/Speaks fine while outside, on the moon.
Takes a missile pretty easily.
Plastic Man's frozen and shatterred into a bunch of little pieces.
Off panel, he thaws, reforms (perhaps with help), but is fully functional pretty soon.
Plastic Man's arm is severed (though the manner it was severed is hardly replicatable).
A dose of heat vision to "weld" it, and the arm's good as new.
Survives welding again.
Durability
Plastic Man spent 3000 years under the sea, existing as tiny pieces.
He was completely sentient and cognitive the entire time.
He's immortal, and, as Plastic Man puts it, unkillable.
He didn't age, but he did "evolve".
He's now untouchable by telepathy, and seems to have developed a greater resistance to fire and cold.
The fire resistance was demonstrated vs. Fernus (scans later)
The cold resistance-
While extreme cold has always been a weakness, nowadays Plastic Man's recovery from it is "Damn!" fast.
He's unlocked from a cryo-chamber designed to take him out, and simply complains about about a "kink in his neck".
Lolz.
And, finally, the upgrade to a completely non-organic being seems to allow him to reattach his limbs like Morph.
Morphing Ability
The most prized ability of Plastic Man, his ability to shift form and make virtually whatever he wants.
Here he morphs into a decorated soldier
First discovering he can shapeshift:
Morphs into Batman.
A can of bugspray.
A giant cat (shows he can make a second mouth).
Morphs into a dress and it's a good enough shapeshift that Barda's fooled into wearing it. Read for major lolz.
Fully functional tank.
Hot air balloon.
Morphing
Morphs into a raft, fools some criminals into using it as an escape vehicle.
Almost duplicates himself. jockey
Creates two heads, each capable of the sight and speech.
Fools a villain into thinking he's a giant doomsday bomb.
Champagne bottle.
Proving to Batman he can color change from his usual skin/red/yellow/black/silver scheme (though it takes concentration).
General Stretching Feats
Turns himself into a "body wrap" for someone to hide them.
Keeps "stretching speed" with a bus's travel speed.
Catches Impulse.
Chases Impulse.
He's the JLA's emergency landing pod.
Creates a thin enough probe with his finger that it can enter through Wonder Woman's ear and take out a miscroscopic probe that's affecting her brain. 🙂
Holds his grip even while Impulse runs at superspeeds.
Supes is shooting backwards from a blow at extreme speeds. Plastic Man intercepts- also a durability feat.
From the outside, invades the inner workings of Tezumak, a superpowerful robot, and slows up his gears.
Stretching
When the league is tiny-sized, he uses his body to join a photon together.
Forms a really long noose to drag up a victim to his position (he's being controlled)
Uses his body to patch holes in the Watchtower (which is on the moon).
Restrains a bunch of bricks.
Ice forms around Diana so cold that it transcends absolute zero. Plastic Man goes so thin that he can slip between her skin and the ice, and then press outwards as the league applies force on the outside, to break her out... pretty impressive, IMO. 🙂
Stretching
Goes thin enough to slip into a safe in the fortress of solitude. 🙂
Goes at it for a bit with a White Martian, stalemating with stretching.
Holds a person inside him.
Makes his ear bigger for super hearing.
What happens when Plastic Man goes berserk.
Morphs to be super strong.
Escapes through the toilet.
Physiology/Mind/Ability
Operates perfectly under water.
Can't be mind controlled.
J'onn helped Plastic Man deal with his traumatizing 3000 year experience immovable at the bottom of the ocean. The manhunter prays for him.
In Dreamworld, Plastic Man liquifies because his thoughts are "too fluid".
"If that doesn't give you an idea of the level of power he hides behind that doofy face, you're brain dead."
Batman commands healthy respect for Plas.
As does Spectre, who claims Plas's true power is in his mind.
Plas hypnotizes himself to forget his hero life so he can be a good dad. This is post- 3000 years under the sea.
Hits Heatwave pretty hard.
(They got his glasses color wrong here. ha-son)
Physiology/Mind/Ability
Talks/Breathes fine underwater as he pwns Black Manta. Also a comment that he's insulated, so presumably immune to electrical attacks.
Pwns Dr. Polaris, who can't directly affect Plas with his powers.
Easily stops a car.
On a team with Spectre and GL Kyle, Plastic Man knows best the fine line between mind and manifestation.
