I like manga that deals with cloning and the conflicts between clones and originals...
I know:
Tsubasa RESERVoir CHRoNiCLE
Enchanter (only look-alike characters though)
Spiral: Suiri no Kizuna
Tales of the Abyss

Do you know any more?

ES
To Aru Majutsu no Index 2nd arc I think
To Aru Kagaku no Choudenjibou
Akumetsu clones working together no conflict

ES
Chobits <-- prolly counts. shrugs

Shuuseki Kairo no Himawari <-- there's a one-shot about clones and their point of view in life.

Clones are 'farm' and 'harvest' for organ transplant..a bitter sweet one-shot. The conflict is all bout the differences between real humans and clones. kinda different though. 🙄

I know for a fact that SUPERIOR has clones and conflicts and all that. This demon girl is the king of the demons and she tries to take over the world or something. The humans send this one guy to kill her :eek: , so the demon girl acts like a very weak demon to get close to him, then kill him. Slowly but surely, she starts to like him and doesn't want to go back to her demon king duties :D . So she makes a clone and everything gets way out of control. :eek:

It's a really good series and I highly recommend it. 😮

Another one i would recommend in Kamichama Karin.

Some of the people are clones, and some of the characters were changed back to little kids, and some have other people inhabiting another person's body. But all of the characters can change into gods.

It's a long stretch from what you were asking for, but it's a good series and you should give it a try.

P.S. Also check out Kamichama Karin Chu, the sequel! 😁

you got donuts?

cool thx for these awesome suggestions^^

oh! Franken Furan is a MUST!!!

Arcana Soul -- They're not intentionally cloned but still duplicates.

There is some drama when the clone realizes that she is a clone and not the original.

Partner -- Maybe. I can't remember if they're actually clones or just zombies.

Reading: Kingdom, Sangokushi, Historie

Jinzou Shoujo maybe?

If you read into it, it explains about the cloning part.

Dismember and Eternal Sabbath (near the end we find out who the clone is).

Edit: Whoops someone recommended ES already. 🙂
