Aquaman

I particularly prefer Aquaman Regime to Aquaman Prime. The former has a spectacularly stropped special second move called Trident Rush which involves a thumping sharp series of trenchant trident strikes that can knockout foes in twos. In case it's unclear, the trident is Poseidon's.
The latter has a super shitty second move called Atlantean Hero which involves summoning someone of lesser value to give supplementary support, or rather provide assistance.
It might interest you to know that he hails from the throne of Atlantis.

Bane

Got three terrifyingly violent versions of the big guy. The Prime version stands out for me though. And the Luchador version too. Most importantly, I'm fanatic about his Break the Bat ability which has him unleashing utterly unblockable venom fueled pummelings.

Batgirl

I kinda love how she uses a smoke bomb to cover her ar.se as she attacks from a distance. Talk about the art of deception, or rather tactical advantage.

Batman

Got five fracking versions of the Dark Knight. Been a Batman fanboy since I had baby teeth. Love the Arkham Origins costume the most.

Black Adam

His lightning aura is enough. The black magic aura dishes dirty damages if he's hit.

Catwoman

Her bladed claws and acrobatic assaults are tantalizing to watch. She merges strength and ability to unleash unstoppable barrages of pain.

Cyborg

This half-man half-machine makes me want to get molybdenum limbs and a targeting system. He comes complete with technology's vast destructive arsenal.

Darkseid

A rocky monstrous beast that throws outrageous omega blasts and uses telekinesis. You get the picture.

Deathstroke

Got four versions of the contract killer ninja. I like the original costume basically because of the promethium armor. Love the Arkham Origins costume completely 'cause his personal arsenal's accommodated adequately — there's room for all the toys. I also love how Deathstroke conducts himself in an arrogant, or should I say superciliously pompous manner. I, too, would swagger if I was thoroughly trained in ancient Japanese martial arts and employed especially for espionage and assassinations. It's always amazingly wonderful watching this paid mercenary make moves with an air of overbearing self-confidence. Deathstroke is without a doubt the undisputed virtuoso of death.

Doomsday

This horrifying hero killer is of Kryptonian origin. His Earth Shake move is oddly reminiscent of The Incredible Hulk's trademark Hulk Smash — in its cheering sunniness. Apparently, DC just can't help imitating Marvel. And if imitation is indeed the highest form of flattery, I haven't the vaguest idea if Marvel would be anywhere near flattered.
Nonetheless, this towering creature called Doomsday has a super weird Fast Regeneration ability which rapidly results in ultimated unopposed strength.
Doomsday is catastrophe personified. Annihilation is his religion. Brutality is his forte. Demolition is his natural appanage. Mass Destruction is his prerogative.

Green Arrow

Of the three types of Green Arrow in my collection, Green Arrow Insurgency tops the list. His extremely exclusive Savage Blast move makes for good theater. I just love how he uses every kind of arrow at his disposal to typhoon and waylay his opponents. Talk about an arsenal assault.

Green Lantern

Green Lantern Regime is a pretty good boxer. Green Lantern Prime is better. Way better. Green Lantern John Stewart is the best boxer among the three (and in the whole game), as far as I'm concerned. Plus, he can use the power of his ring to unleash a melee ballistic combo. This burly black bloke is the best bet when it is time to throw mean swings and powerful punches with perfect pro precision.

Hawkgirl
She's a hawk in every sense of the word.

Killer Frost
Three words: Cold as Ice.

Lobo

Lobo's my main man for all the right reasons. You're looking at a loaded shotgun, a space hog, and a bad attitude.

Martian Manhunter

I'm a fan of how he phases through the ground and reappears with the most devastating uppercut under unfortunate opponents.
He's also as telekinetic as Darkseid.

Raven

Even though she's supremely satanic, I kinda enjoy the way she flexes her demonic heritage with impunity.

Scorpion

My hands-down favorite. He's like a scourge surpassingly studded with metal. I call him the scorpion of absolute necessity.

Shazam

I haven't the foggiest notion how he's able to summon the bolt of Zeus and hurl it at anyone. I have a vague impression that Shazam is apparently affiliated, or rather related to Zeus.

Sinestro

The yellow side of Green Lantern, or rather a middle-aged Green Lantern in yellow uniform, or should I say spandex. Never mind that though. Sinestro's might's mostly manipulated and powered by fear. Sinestro's probably the only one who can call out to asteroids and acquire answers apace.
That's absolutely amazing if you ask me; asteroids a jillion million miles away actually hear his voice in outer space, beyond the Earth's atmosphere and answer him to the quick. In case it's unclear, asteroids are any of the small rocky celestial bodies found especially between the orbits of Mars and Jupiter. You're welcome.

Superman

Got the Prime, Man of Steel, and Regime versions of Superman in my collection. Used to have the Red Son version too but right after the last IGAU update, Superman Red Son "magically" disappeared. No traces at all. That bug was a real downer. Emailing the developers availed me nothing. Really bummed me out. Regardless, the Son of Krypton works best for me in his Man of Steel alter ego.

I Love flash,Death stroke,cat woman and Green Arrow dey easy to control

How could I forget to mention The Flash? Got three types in my collection, but it's either the Prime version, or the Regime version, that does it for me. I find the Elseworld version very weird, most especially, the terribly clunky mediocre masking. Regardless, The Flash does live up to his name — with sudden and often brilliant bursts of lightning quick attacks. He's also got a flash of wit which I find fantastic. Like how he says, 'Let's make it quick.', before beating the daylights out of opponents.

I play online with killer frost, animated harley and static. Along with the max gear cards I have, I never lose. Another really bad ass card is nightwing( the gold card). A power generating gear and he will keep draining and beating everybody. I usually use him or static to take out full teams singlehanded

Op, where is the joker na?
I love his finishing moves

You're a Bawse. Harley Quinn is one of my toughest opponents. Words just cannot explain how much I hate her health gain trick. Not to mention the super annoying and seemingly sexual question she spits while she's slaying you: 'Am I too much for you?'. Her accent and voice vexes me more. Rarely put her on my team though. Got four versions of The Joker's grotesque girlfriend, but I love her Arkham version the most.

Forgive me, but I find The Joker very drab.

Nightwing is an amazing fighter, no doubt. I just have a problem putting up with his pathetic power drain diabolism. Especially, or rather specifically when playing against him. Seriously, it is incredibly infuriating. Lex Luthor has that tactic too.
