To be honest and this is just my opinion, your story telling is all over the place, Paradox, Eren being an EVO titan, dude your making my head hurt with these stupid ideas, just let Rex be only person in the Attack on Titan world, adding more characters and nonsense stuff is just a headache...

Para-d(o)x get the reference I wonder how he will come into play also I would like if you continue

It’s Connie. Not Conny

This is actually my second time reading this story but it’s only recently (within the last month or so) that I had my love of Generator Rex ignited almost as much as Ben 10. Anyways, I’ll just say this upfront: this story is THE BEST Generator Rex crossover out there. I’ve searched all of FanFiction & Wattpad and none of the stories I’ve found even come close to the quality of this one.
Almost everything about this crossover is great; the grim tone due to the setting taking place in the AOT world, Rex gaining new builds (something that I’ve noticed a lot of authors don’t really feature), Eren becoming a cyborg titan shifter due to being consumed with one of Rex’s Smack Hands, Black Knight’s fate after the events of the show being revealed and almost everything involving Breach from her tragic friendship with Ilse, there being an evil alternate version of her, her potential romance with Hanji and her recent decision to go out and discover herself. But I think my favorite part of this story is something I just realized you do with the main characters of all your stories (that I’ve read): you don’t confuse Rex being extremely competent with him being overpowered.
Anyways, just wanted to get my thoughts on this story in it’s entirety out since I’ve already done so with Ben 10: Aliens vs Assassins and because Generator Rex has a relatively small fanbase in comparison to Ben 10.

Please continue whenever free cause i'm a huge fan of both of the shows and crossover in general and I love your story telling.

Loved it huge fan of Gen Rex,Attack on Titan and Ben 10 i really enjoyed Mina and Rex relationship in the first chap hope it goes on,good writing can you write fanfic on ben 10 crossover with Attack on titan in the future to make ben balanced use his all aliens till Alien Force cause ultimate forms get too OP for the crossover having a teen mature ben from AF would be great can't wait to read other chapters.

cara, muito incrível sua historias,

Yes an update! Great chapter dude. It was pretty interesting to see the perspective of the other aot characters.

(Nack snickered and smiled. "There's also Eren, you know. But I guess it makes sense. Eren isn't tall enough to sweep you off your feet."
Mylius couldn't help cracking a smile at that remark. Meanwhile, Eren sneezed while walking about in a hoodie he had been given. For some reason, he felt a pit of annoyance despite no one around him bringing such emotion out.
"What are you talking about?" Mina was clueless, however. "Yeah, Eren's not tall, but he's a good guy too. You know he won't be happy if he heard you say that."
Both Mylius and Nack glanced at each other with a sneaky smile. One word echoed in their head before they looked away.
'Clueless.' They thought.) Hehe that was pretty funny. Who knows maybe Mina will be one of the few female characters to receive a harem lol, I jest, I jest. Be a funny omanak thou.

So soon this will the another time a blonde named annie endangers rex’s Live. Lol can’t wait for that.

Also good on you for owning that asshole, lol Yuri equals being a perv, hehe that’s not homophobic at all.

So we're at the On A Horse's Back Almost The Entire Time Arc...oh, forgive me, I meant the Female Titan Arc.
In all seriousness though, I'm eager to see how things will differ from canon. I'm particularly excited to see the scenes showing Rex and the Female Titan interacting with each other.

I like the friendship between Rex and Six.

Okay.

There's never enough yuri.

Poor Oluo, haha.

Hmmmm.. Yuri huh? Even though they aren't even gay so I guess another perverted author?... Okay I just want to focus more in their battle and story not romantic
Rex having hard time against female titan? So I guess rex past experience is weak as hell even though rex enemy in his own series can kill all types of titan except the colossus titan
Rex enemies are more powerful than the titans and more dangerous even the armored one and rex getting hardtime OK... That's some level wanking shit right there though early writing dealing with romantic pairing that's relationships don't work like that it seems another author doesn't know lovelife writing about couple relationships even they had no experience in it.. Just focus on building up first
1 month interaction has a romantic relationship hahahahaha xd
