The Oushiza is a one-of-a-kind Marzan unit, specially designed for one of its most battle-hardened generals. Battle data and accounts on it are rare since the few that reported seeing it were battle-shocked and couldn’t remember anything except that it was ruthless and precise.
A pinnacle of Marzan destruction.
Similar to the Hyouga (reimagination of the Zane’s Titan Mech Battle (71738) set), the Oushiza is a reimagined mech build in reFrame proportions and style of the Demon Bull King (80010) set from the Monkie Kid theme.
This build also tests out the new heavy reFrame v4 as part of my overhaul of the reFrame LEGO mech frame system. I had already made a sample design using the heavy reFrame so the goal with the Ouzisha was to really push the limits of the frame in terms of weight, overall bulk, and stability.
Lastly, slightly rushed this build to make in time for Halloween. The demon look was just perfect for the season.
Inspiration and sources
I tried to retain as much of the Demon Bull King’s original design aspects so a lot of the color blocking and parts selection were based on that.
The key areas and designs I wanted to keep were the following:
- Trans-orange shoulders
- Rib cage with trans-orange body
- Magenta thighs
- Lower leg and feet shape and color blocking
- Nape design (tubes that formed a neck/spine area)
- Flamethrower weapon
- Overall bad-guy look
Notable existing mecha inspirations for this build are as follows:
- Zaku – UC Gundam
- Goss Harag – Monster Hunter Rise
- Gundam Barbatos (for the legs)
- Guren Type 02 – Code Geass (for the left arm)
I. Head Build
As with most of my builds, the head build starts and sets the overall design approach for this mech. I knew I wanted it to be mono-eye even before during the planning phase, attributing the mono-eye to the Zaku design from Gundam.
Another design goal for the head was to give it horns and make it look like an oni (from Japanese folklore). The shield tile was used to give it that fanged / strong jaw vibe.
II. Initial core body
The body build started from the cockpit cover. I wanted to have a transparent orange central cover to mimic the original design’s glowing core center. I also knew I wanted to replicate the rib cage look so that was the goal for the side cockpit covers.
The Metalbeard beard pieces were actually an accidental fit that I instantly knew I had to have to establish the chest shape. The tricky part was connecting them as they had to be in a certain angle with a compact connection point. This was achieved using a minifig handlebars utensil piece.
III. Waist, sample shoulders, thighs
I considered using the same trans-orange windscreens on the original set for my rebuild’s shoulders but found them too large so ended up using these old windscreen pieces. Luckily I had the hinge piece that connects to them in black so it was just a matter of getting the right angle and avoiding the trans orange axe heads on the body.
Decided on the Magenta 4×6 curved wedge piece to cover the thigh as it had the ideal thickness to make this guy look like he squats other mechs for breakfast. Built the front waist assembly as well just to get a better feel of the upper thigh area.
I also already experimented on the left arm at this point but scrapped several designs since they were all too chunky.
IV. Lower Legs
This was a first for me as I rarely use huge bionicle / Hero Factory pieces in my builds, especially for armor plating. It was just that these spiked knee guards (I think they’re originally shoulder armor?) were the ideal shape and size to cover the knee joint. I actually use a slightly reverse knee joint assembly for this (very similar to the H’da) so the thigh section would be popping forward, giving it a less human leg anatomy.
The feet have a similar assembly as the Zenithal build that it uses part number 92692 (Plate, Modified 1 x 2 with Angled Bar Handles on Side – Closed Ends). I wanted the “toes” to be similar to the original set with two big toes at an angle.
V. Claw weapon studies
Moving on to the arm designs, a lot of time was spent making the big left clawed hand. The last big hand I built was way back with the Gigas V3. I was also referencing off the left hand of the original set but as that was a 3 finger assembly, I looked at the Gigas hand more.
The plan was to give it 5 fingers even if the normal reFrame hand is only 4 fingers. The first version actually used Mixel ball joints at the knuckles and while they worked and were very rigid, I wasn’t too happy seeing the LBG joints. A 2nd hand was made using black 1×1 plate modified with handle bar that had almost the same finger articulation but looked better. The final version swaps the black 1×1 modified plates to pearl gold.
VI. Unused / Scrapped
One idea with the rebuild was to retain all the weapons on the original and incorporate them into the rebuild.
I actually built an axe head that was the same size as the set’s axe head but had less gaps. The issue was that with the right hand having a mounted flamethrower and the left hand being a claw weapon, an additional axe weapon was too much. Also since the newer hand had loose knuckle joints, it wouldn’t be able to hold the axe weight on top of the already heavy left arm and shoulder.
The right forearm in the middle of the pic was scrapped for being a bit too wide. I went with a thinner, more aggressive shape to the final forearm.

Post-build extra notes
If you’ve been following my works for a while now, you’ve probably noticed how I’ve been inactive/not-as-active on social media as of late.
Honestly with all the things going on globally and especially in our country, it’s pretty hard to be motivated to do creative things. Kudos to those who are still going strong but personally, I really had to take a creative break. My LEGO room actually became a storage area for a bit while we were preparing our spare room for our baby’s nursery.
A lot of life things also happened last September and I’m now a Dad, albeit much earlier than what me and my wife expected and under not-so-great conditions. Thankfully, our son is recovering with each passing day and we’re looking forward to having him with us here in our home (and I’ll give him his first LEGO room tour 😍).
I’m returning to LEGO building for the time being but might suddenly go on a a hiatus again if further life things require it.
If you’re curious about getting a custom reFrame from me, simply check out my Commissions section here in my website. I’ve written all the details you might need to order your own custom LEGO reFrame mech build and what kind of customization options you can get.
Do take note though that I only do this in a very limited capacity.
I open up slots for commissions here on my site and also announce it over at my various social media pages. I’d suggest following me on any/all of my social media pages below to stay updated on my work and commission slots.
reFrame v4 currently in development
ReFrame V3 instructions will be 50% off over at my shop.
reFRAME v3 Instruction Manual
The reFrame System is a modular brick skeleton aimed to help both new and veternan brick mech builders create their own designs in a consistent size with modular capabilities. It was originally designed to be a basis for all my mechs in the Mech Wars universe. Having gone through a number of upgrades, the V3 reFrame can now house a minifigure pilot in the chest without sacrificing aesthetic or articulation.
