Well if this means from the comic... Dragos is probably the toughest mofo so far in the Beast Legion1 Universe...
Well,I can say my one and only powerful one.Edward Foster The Future God.
Well,I didn't put him in any comics cause' i know thats actually cheating to have an immortal god on your side.He just outside of the universe watching everything.Yes he can kill the universe in a snap of his finger but nah,that would never happen.He just looking at anything fascinating.Oh did i heard that god wouldn't accept in this thread soo....Let's just say its Neil Anderson.More like a villian than a nice happy-go-lucky jackal man.He is still forgotten.His true self is a very strong one tho.
Darn he has that evil satanic power in him....somewhere...

The most powerful character in my webcomic Infinite The Journey
is going to be the leader of the guardians.
Zaithor So' Zen
Powers were given to him by the great spirits after winning a tournament. And he is the fastest in the realms and the strongest. With his spirit sword he's able to summon and wield it whenever he can.
Well, I'm one of those people who doesn't like creating OP characters either, haha.... But I suppose if I had to choose a character or two to back me up it would be:
1) Milo - he's of slight build and doesn't have magical powers like some characters up in here, but he's bold and pretty competent in fighting at least
2) Gen - he deals with demons and ghosts and fights 'em all the time (heck there might even be one inside of him), so if there's anyone who I can rely on to at least protect me from the baddies, then it would probably be him. hahah
I've got a character called Penelope from my comic Girlfriends. She's rich and rude and steals her father's large sniper riffles to shoot people with. I don't know if she's my most powerful character, since all my girls are professional killers, but she's likes to brag about it the most. She also looks totally cute.
oh man i love nigh invincible/peerless characters.
they always seem to be an impassible hurdle that no one can go up against. the aspect of someone beating that character, protagonist or not is always such a treat because it implies that there WILL be someone stronger.
Gren Delfaust.
the absolute strongest character i've ever made. she hasn't been seen yet, you only see her silhouette in scumbag heroes.
born half human half giant, she was the final product of her mother's long selective breeding process that would create the strongest living being on the planet. she wasn't able to grow up to her mother's size but she has the collective strength of all giants in her lineage stacked on top of her father's rare genetics which repel magic. she and five other great heroes quelled the war between magical beings and humans, creating an era of peace.
now she just sorta lounges around at a naval base in the middle of the atlantic ocean looking to fix any problems at sea.
Strongest OC? Imma definitely saving that spot for final boss in my story 
At the meantime, here's my strongest supporting character (much imba than the hero himself) in Tales of Gallantry
Gavis Van Harten
A veteran soldier who lost his right arm from previous war; however discover his talent in magic thus taking the role as a battlemage. (yup...if its a game, he'll be a tanky magic user at the frontline)
Can manipulate his spiritual energy into shapes. Usually form a spiritual arm to replace his missing right arm.
Character design inspired by Liam Neeson's badassness!
my webcomic doesn't have much fighting until it reaches volume 2 but the most powerful is Silver.
I can't say much because it's story plot as well but I'll say she's the most powerful of all Angels which can make the earth tremble when she unleash her powers.
She's strong, agile and with matching confidence and those wings can fly anywhere. Although she's a pacifist and would rather prefer to just talk it out if she can. But she won't hesitate if she needs to protect her comrades.
I'll go for Spud Guy protection.
Just look what he did to Bieber before!
He came from a potato plant that Chuck Norris spitted on! Then grew up to be one badass spud.XD

You ever purposely search out a thread? I do.
In any case, I feel bad for not contributing to this long dead thread, so here goes.
This here is Indrus Gamorett, an angel with the ability to negate any physical force with his fingertips. Additionally, his hundreds of years of training has allowed him to become the most technically skilled martial artist in all of Heaven.

Wanna meet her? 
The most powerful ones have left the Intrepid Soul designs eons ego, but right now they are in their correct order, Suren (she/her) the Princess of Jade whom orders the Sentient Mind to bring Thought, Memory and Emotion to the Living Flesh:
Bahatar (he/him), Indra's bloodline who can pull the World's Bones from the Living Flesh and Sentient Mind:
And Isolde (she/her, they/them), the current World's Bones incarnation who currently has issued the Decaying Bones order which is keeping the planet from healing itself.
All for my novel Jade Kingdoms btw. They sound godlike and what not, but I promise it's not as glorious as it sounds. Each of the three realms comes with severe ailments that chips away at their strength ever since the Genesis Trinity failed to give life a proper headstart.
Let's see... my characters are nowhere near cosmic level but they do have their strengths. I'll pick one of them to talk about.
So this here is Serenity. She has a power known as a Surge, which is more or less a passive ability that remains dormant in the body until activation. Hers is called Omnifiber, and when she uses it the power multiplies and enhances the fibers in her muscles exponentially, giving her super strength. As demonstrated below, where she crushes and bends steel beams.
And here she is when she doesn't use her Surge, the fibers in her hair are also affected by her Surge. Call it a side effect of the power. So when she doesn't use Omnifiber, her hair becomes silky instead of stiff and tangly.
In the world of Alpha Edrox1 only one character fulfill that category, his name is Irokah Ulmite, he has the higher level of all living beings and his powers are identified as Multiversal and Nemesis, which indicates his capability to adapt to every single opponent in any possible scenario, but still, he is a kid, so his lack of experience and knowledge is a great disadvantage, he needs to know all his powers (and this is a path that will never end for him) in order to become invincible. At least some of his powers react naturally under some circumstances.
each of my main hero OC's are very powerful, and each specialize in one aspect, but the most powerful would have to go to the star of my current chapter venom thorn, she has the standard super strength, speed, stamina ,durability, telepathy, empathic powers, heightened senses, and higher IQ, she has chlorokinetic(create and control all plant life) powers ,has an almost broken healing ability that she can use on others and has the ability to make impossibly deadly poisons , oh and i almost forgot to back that up with she is a kung fu master
