Lego Galaxy Squad CLS-89 Eradicator Mech (70707) Review

Ever since I first started building and playing with LEGO in the 80s I was a big fan of the sci-fi space theme. Currently, LEGO does not have a sci-fi space theme in their portfolio (unfortunately). I’m calling it a sci-fi space theme because LEGO does currently have some realistic space-themed sets on the market. Nothing like the Lego Galaxy Squad CLS-89 Eradicator Mech though.

Anyway, I was browsing one of the many online local marketplaces the other day and came across an advertisement for three used LEGO Galaxy Squad sets. Looking at the images piqued my interest immediately.

2013. This was the last year LEGO had a proper sci-fi theme on the market. I bought the sets I saw online, picked them up, and fell in love immediately. I think the LEGO Galaxy Squad theme is, although not perfect, amazing in many many ways.

Without further ado, here’s my first Galaxy Squad set review. The LEGO Galaxy Squad CLS-89 Eradicator Mech.

LEGO Galaxy Squad

Alright, I lied a bit. The review is coming, but I first wanted to give you an overview of what Galaxy Squad actually is. All themes have a premise and this one is no different. 2013 was the only year this theme was made (The theme was discontinued in 2015) so not many many people know much (if anything) about it.


A mysterious race of evil alien Bugs is swarming across the galaxy, capturing civilians in cocoons and turning one planet after another into a Buggoid hive. There’s only one force that can stop them: the ultra-elite Galaxy Squad. The Galaxy Squad is a section of the space military, equipped especially for fighting alien Bug menaces.

The theme features a group of humans and their robotic sidekicks defending planets from an impending invasion by seemingly malignant alien “bugs”, which resemble anthropomorphic insects.

The humans and robots are split into different “teams” or “squads”, distinguished by the designated color of their minifigure printings and vehicles, as well as a unique insignia. These teams are as followed: Blue Team, Red Team, Green Team, and Orange Team.

The Bug colors are mainly dark grey, lime green, and dark red, despite their exoskeleton colors being Olive Green. The aliens consist of Mosquitoids and Buggoids (the latter of which has a red as well as a green variant). The Bugs are known to be primarily based on Earth insects.


Jack Fireblade is the main minifigure of this set and he’s amazing! His skin is classically yellow, the helmet mold is awesome and the grey armor looks really good against the rest of his orange suit. He has two faces. One really determined and one with what looks like a breathing mask. It looks excellent. Jack also gets two big space blasters which make the Star Wars blasters look like pea shooters.

The orange robot sidekick is pretty darn great as well. I love the Transformer-like headpiece. The armor print on the torso has the opposite colors as Jack’s and this particular robot has a very cool orange armor piece that goes over the torso and includes wings! The robot also gets a massive gun or launcher type of weapon.

The Build & Features

The Drones

The LEGO Galaxy Squad CLS-89 Eradicator Mech has two adversaries. In this set, it’s a couple of bug-like Drones and they look way better than I thought they would. The Green, red, and grey color scheme combined with the transparent greenish/yellowish pods look amazing! The pods almost look like they glow. In fact, they are capture pods and will fit minifigure!

Building the bug Drones is really fun and the build is excellent! Besides the pods, I especially love the legs and slightly movable head. You can display the drones in different positions and look quite menacing. One of the drones has some sort of wings on it which looks equally good but also brings a bit of diversity to the set. I just love the overall look and feel.

The Mech

The cockpit of the Mech is a pretty straightforward build but it does have a few really nice details and even a storage compartment that houses a scanning device or maybe a bomb. It can be whatever you imagine I guess. It has a tiny printed cockpit piece and a few stickers.

The orange color looks great combined with the white and grey. And Jack Fireblade has quite some room to sit in. The ‘wings’ of the cockpit are really sturdy put on top of the cockpit and actually serve a purpose. More on that later. There are also two flick-fire missiles that look pretty good.

The top and middle part of the Mech is up and Jack’s guns go there as well. It’s a great way to store them but also work great on the Mech as additional guns. The use of a few Technic parts make the whole build even more sturdy and eventually, you are building some kind of a second cockpit. This seems odd, but the LEGO Galaxy Squad CLS-89 Eradicator Mech is full of surprises. It can turn, twist, and transform quite a bit.

The cockpit you have built earlier can be taken off and used as a spacecraft. With the spacecraft doing its thing, the secondary cockpit turns in such a way that it becomes the primary one. Now the robot sidekick is able to drive the Mech while Jack is flying around.

Big Guns

When building the legs and arms of the Mech you’ll find a lot of cool parts are being used to create them. It gives the whole thing a pretty unique look and feel. Especially for a 2013 build! The legs are extremely sturdy and very well designed and put together. And that’s a really good thing because the Mech can be a little top-heavy.

One of the arms has an amazing-looking Gatling or minigun while the other arms features a flick-fire rocket missile battery. The big gun the robot sidekick has goes on the minigun arm. This is once again a great way to store a weapon whilst also being a great addition to the overall set. It seems to function as a targeting device in this case.

My Thoughts

The LEGO Galaxy Squad CLS-89 Eradicator Mech has become one of my favorite sets to date. I am a little biased because I just really like sci-fi space stuff, but I just love the way the Mech looks. feels and how many features it has. It twists and turns and has tons and tons of playability as well as displayability.

I also really like the Drones. I thought they would be ok, but they are so much better than that. They just have that great Starship Trooper Arachnid bug look and feel. That combined with the great-looking colors makes it even more awesome.

The minifigures are really good too. I especially like the helmet mold of Jack Fireblade and the head mold of the robot sidekick. Once again, I still have no idea why LEGO did such great molds on sets like these but give minifigures like Darth Maul a crown to define the shape of his head.

If you like sci-fi space-related LEGO, you should definitely look into getting a few Galaxy Squad sets.
