Like all of the Bad Guys books I found this one entertaining but I’m not sure the series needed to carry on. I’ll keep reading the series as Aaron Blabey writes them but they’ll never be as good as the first 3 books in the series.

I laugh out loud every single time. And this one was no exception.

Absolutely love how they referenced the first 10 “episodes“ in the story!

With Marmalade now gone back into space in disgrace, the Shadow Squad G (our two hero teams now one) have all gone on to become loved heroes and have new successful lives, but Snake has been closing himself away from the group and has recently been listening to a mysterious voice in his mind. His crew comes to check on him and they’re all get a taste of the voice’s powerful force and find a strange door. It turns out it’s one of Marmalade’s powers he left with them. A (100%/Outstanding)

Daughter enjoyed reading this with her grandparents as our weekly long distance book read.

This story focuses more on building up for the next book and the plot relies on a Bad Guys version of MTV’s Cribs to get the ball rolling. Nothing really happens here except the promise of impending chaos in a following title.

The Bad Guys feel kind of weird right now, like they're building up to something HUGE I have no idea what's going to happen, but I'm here for it.
This reeaally feels like it's the third arc in this series and things are going downhill for our boys and girls.
I love our growing gang, everyone involved is so nice. We were in such a good place keeping everyone happy and nice and then this book happens to poor Mr. Snake. I'm excited to see who's he's been talking to, and who owns the other mysterious voices.
I hope Nathan joins the gang. Him and Milton would be my favourite

Oh wow! So The Shadow Squad G has defeated evil and is now partying in the pool! Except Snake, he hasn’t left his home in over a year. Something is up…can the gang help him?

This book was so great! Action packed but filled with friendship and loyalty!

Ever since the Bad Guys triumphed over the aliens in the last book Snake has been spending WAY too much time alone. The others are worried about him. And they should be, because the alien parents have just revealed some disturbing information to their wayward son. Something about the powers that were never supposed to be unleashed or the universe would be doomed.

Those who were paying attention to the foreshadowing in the last book saw this coming. This book is basically a build up to the next book in which I suspect there will be some resolution. Snake is having quite the moral and personal dilemma in this one, and it has dire consequences. But Snake isn't the only one. If you pay close attention, several of the heroes seem to have been letting success and the taste of power get to their heads. Perhaps they all need a lesson. There are also some rather interesting abilities hiding in Ms Fox and Piranha hinted at. This will have readers begging for the next book in the series to come out NOW.

Notes on content: 1 darn and 1 heck that some parents will want to know about. No sexual content. There's intense psychological moral battles going on, but no real physical violence. Know the kid you hand this to and whether they can handle the moral conflict. The font style is kind of creepy looking and that may influence how some readers take this.

It was a 5/10 it didn't really have a clear villain, and it didn't really have that much suspense either.It did have a good plot, and was really funny.

It was basically about, a reporter doing special coverage, she was allowed access inside the bad guys now good guys headquarters. The good guys had more money and they had different personalities. Mr snake had gained psychic powers that let him see anywhere on earth. Then while he was looking around the building, a strange voice tells him to look deeper in space. He looks deep in space and finds a door. A voice tells him if he opens the door, it will give a world where he rules, and he is powerful and rich. He hesitates but opens the door, the gang is looking for Mr snake and they find him. He is evil and more powerful. He persuades his other friends to join him, but one doesn't it is Mr piranha. The voice says to Mr piranha he has an hour to decide to join his friends and be rich and powerful, or life boring life trying to be good. Mr piranha fights back and gets his friends out of the evil trance. except for Mr snake. Mr snake unleashes a giant three headed snake, on his friends the end to be continued.

I enjoyed Snake's return in the previous book, and this one is an absolute ride. The book begins by showing what everyone is doing now that they have defeated the villain from the previous ten books, but Snake's new, overwhelming powers come with great temptation from a voice out in the universe. His internal struggle is both realistic and wonderfully campy, and this takes the series in a fascinating new direction.

Readers who got tired of The Bad Guys and were waiting for the central conflict to resolve will want to move on after Book 10, because this story introduces a variety of new problems and directions for the story to take. However, this is perfect for the kids and childish adults who want all the Bad Guys content they can get.

Sometimes you feel that a whole book that is foreshadowing the upcoming arc is a bit much...and depending on how you feel about what I just stated will decide if you enjoyed this volume or found yourself awaiting what is to come! Aaron Blabey is on a mission, and I feel that while one can critique each volume, you cannot deny the series and the way it's been put together. I hope this series is talked about decades later because it is fun and it does cover a pretty broad age group in my humble opinion. This definitely gave me an entire MTV cribs moment and what is funny is with MTV all but gone, those reading it won't know the source material. But then again, some of the Star Wars jokes may live on forever. Another solid and fun volume.

In my Quest to Finish Series I Left Off Without Reason, I’m going back to the Bad Guys.

Now, I don’t remember much about books 1-10 but kind of pieced together some things: filler still happens. Lots of filler. So. Much. Filler.

The Bad Guys and their female counterparts are now a team living the high life. Snake has powers. And then stuff happens. And they introduce the premise for the next book in a way like we the reader are supposed to know about, because why not?

As pointless as most of the book is, I’m already committed because I like Mr. Wolf and Fox, and Snake and the emo bird whose name escapes me. It’s too late to turn back on the Bad Guys.

Wolf has finally achieved his dream of becoming a hero, but worries about snake, and soon discovers that his job is not yet finished.

Snake wrestles with using his powers for good or for evil, and succumbs to the evil. A good message for us all to choose what to do with what we are given.

To be continued...

I kind of wonder if the series should have ended at ten. This one does seem to take a dark turn. I do think piranha's lifestyle of the rich and famous is rather entertaining. It is nice to see everyone have a break.

Review from a 5-year old

“Hi. So... do you want to toot or read this?

This story was good. I liked it because it’s almost the weekend, and I wanted to say that my favorite part was when everybody was partying.

And I really liked when they showed me Mr. Wolf. He is nice because he was the one who planned the Good Guys Club.

Superbad. Bad, bad. Really bad. Sad bad. Nervous bad. Toots bad. Hahahahaha I like all of those bad words.

Okay... the last thing I want to say is: ‘bye bye!’”

A sense of anticipation builds, thick and palpable. They seem to be on the verge of something monumental, and I can't help but wonder what it could be. This is truly the third act in the series, and the stakes have never been higher for our group. Each member has grown and developed in their own way, but my heart belongs to Mr. Snake - his cunning wit and sharp tongue always keep me on edge. However, it seems that he may soon face some daunting obstacles. My curiosity piqued, I wonder who he's been secretly communicating with and whose voices echo in his head.

In this eleventh book, The Bad Guys: Dawn of the Underlord , Aaron Blabey continues where the characters left off; however they are much more relaxed and into party mode. The story pretty much is a prologue to what will be happening in the next few books of the series. It's a good start, but I can't say it was the best I've read out of Blabey's books.

That said, I am looking forward to what the Underlord brings us as the books continue.

This one has definitely taken a dark turn. Snake is getting summoned from afar. A dark force wants him to go through a cosmic door and embrace his dark, evil side. Snake is conflicted and does not want to hurt or control his friends, but the power is very enticing. The illustrations range from funny to super dark/Darth Vaderish...but fans will enjoy seeing the struggle. Recommended for Grades 4-5.
