Steeljaw (G1)
| The name or term "Steeljaw" refers to more than one character or idea. For a list of other meanings, see Steeljaw (disambiguation). |
- Steeljaw is an Autobot Mini-Cassette from the Generation 1 continuity family.

Where the Decepticon cassette with a cat-mode is a master of moving about undetected, it is fitting that his Autobot counterpart is one of the best at tracking down robots who don't want to be found. Steeljaw (aka Cubbie) is a tenacious tracker of unmatched skill, whose olfactory sensors can track even the faintest scent for a range of 800 miles. All business when on the job, he can come off as cold, even rude to others, but that's just his professionalism and determination getting the better of him. Off the clock, he loves to investigate odors of all shapes and sizes, and Earth has many new and unusual smells for him to enjoy - the perfume of young women being one of his favorites. Steeljaw has a nearly unbreakable bite, from which he takes his name, and is armed with two solar-powered pellet guns. He can electromagnetize himself to stick to surfaces in cassette mode. His only real weakness is a tendency to rust.

Toys
The Transformers
- Rewind / Steeljaw (Cassette 2-pack, 1986/1987)
- Accessories: Left & right "Solar-Powered Pellet Guns"
- Steeljaw transforms from a microcassette into a robotic lion. His cassette mold can fit in the tape compartments of Blaster and Soundwave (and the many other iterations thereof). For the Hasbro line, he was only available in a two-pack with Rewind.
- There is a notable variation concerning Steeljaw's add-on weapons; initial releases have gold-colored chrome, while later (and more common) versions have silver-chromed weapons. Unlike the humanoid Autobot cassettes, Steeljaw did not get tape-detailing changes later in the line's run.
- It is commonly assumed that the sticker design for his details in cassette mode was originally intended to go on the other side; not only would the "sunburst" line up perfectly with the seams that way, it would also give the impression of a lion's "mane" in robot mode. The most likely reason for the reversal is the fact that it matches the orientation of Ravage's sticker details.
- This mold was later used to make Nightstalker.
- Steeljaw (Cassettebot, 1986/1987)
- Japanese ID number: C-65, C-120
- Accessories: Left & right "Solar-Powered Pellet Guns", cassette case (1987 only)
- In Japan, Steeljaw — like most of the "Cassettebots" and "Cassettetrons" — was only (originally) available on his own single card, first released in the Japanese line's second year. He was released again in the Headmasters-themed third year, this time packaged in a small box with a new ID number, plus a small clear-plastic cassette case he could be stored in.
- Both releases of Steeljaw only came with gold-chrome weapons.
- Twincast (Autobot, 1987)
- Japanese ID number: C-116
- Accessories: Left & right "Solar-Powered Pellet Guns"
- Steeljaw was later packed in with Twincast, the "reborn" version of Blaster. Also, this version is made of two slightly different colored yellow plastics. His body is the same color as other releases, while his legs, feet, head, and tail are a shade lighter.
The Transformers Collection
- Broadcast (Autobot, 2006)
- Japanese ID number: TFC-21
- Accessories: Left & right "Solar-Powered Pellet Guns", cassette case
- Although he had originally been packed in with Twincast in Japan, for The Transformers Collection series, Steeljaw came with plain old Blaster instead; his place in the Collector's Edition Twincast re-release taken by Flip Sides. He also came with a clear-plastic cassette case to be "stored" in, which was originally available only with the first three individual Cassettetrons: Frenzy, Laserbeak, and Ravage. This version of Steeljaw featured gold weapons, one yellow plastic color, and stickers for his tape details.
Encore
- Great Cassette Operation 2 (2009)
- Encore number: 17
- Accessories: Left & right "Solar-Powered Pellet Guns", cassette case
- As part of the Encore Generation 1 reissue line, Steeljaw was released with Ratbat, Ramhorn, and Slugfest. His add-on weapons are gold-colored. As with the version released with the Twincast reissue, the feet, legs, and tail are a much lighter color of yellow plastic than the rest of the body. The metal on his legs are a bright silver and his stickers are now tampographs, yet the cassette details are still on the wrong side.
- In 2014, this set, as well as the other two cassette four-packs, were re-released as lucky draw prizes for the Transformers Celebration 2014 event held at Ikebukuro Sunshine City store's Toys"R"Us, though this was very likely just leftover stock.
Universe (2008)

- Autobot Blaster (2010)
- Series: G1 Series
- Accessories: Left and right "Solar-Powered Pellet Guns"
- Steeljaw was available in this Hasbro Toy Shop exclusive reissue of Blaster (originally available at San Diego Comic-Con 2010) alongside Ramhorn and Eject. Released as part of the Universe toyline, the packaging also has a special foil-detailed outer slip case. This release has the gold-colored weapons and consistent yellow color throughout his body, similar to the Transformers Collection release, but tampographed tape details, like the Encore release, only darker in color. The cassette details are still on the wrong side, alas.
- This set was also made available at the Animation-Comic-Game Hong Kong Fair 2010.
Generations

- Autobot Intel Ops (2015)
- Accessories: Concussion rifle, missile launcher, 3 missiles, 6 slides, slide holder
- Hasbro again released Blaster in 2015 as part of the Platinum Edition toyline. He was co-packed with Perceptor, Eject, Ramhorn, and Steeljaw in a box with an opening front cover. Blaster and the cassettes appear to be identical to the previous Universe release.
- In the United States, this set was officially a Target exclusive, though it was initially only ever found at a single Target store, otherwise only available via the company's website. It was later revealed that multiple Target stores had kept it in their stockroom and eventually put it out on instant clearance many months later. However, it was also stocked by US-based online retailers BigBadToyStore and TFSource, who supposedly obtained it as an import from Asia. It was available in several of Hasbro's Asian markets (namely Malaysia, the Philippines and Singapore; it's currently unknown whether it was exclusive to any particular stores there or not). In Australia, it was sold at Toys"R"Us stores.
- In the United Kingdom, it was both sold at Toys"R"Us stores and officially available via the UK division of Amazon, making this the first official UK release of all the toys contained within! In Spain, it was officially available via the Spanish division of Amazon. In Germany, it was originally available via Bankroft as part of a special "Fan Edition" arrangement through Hasbro Germany, with the help of several German fan sites. Due to low sales, the unsold stock was later sold to online retailer Actionfiguren24.

Notes
- For the original draft of The Transformers: The Movie and several revisions, Steeljaw was going to be called "Cubbie".[1][2] Between the original draft and actual product, Cubbie/Steeljaw is the only Autobot Mini-Cassette whose concept did not change.
- Where Ravage and Laserbeak had dedicated vocal performers in the Generation 1 animated series, the noises Steeljaw makes are mostly library sound effects of growling, hissing cats, and metallic "wronk wonk" sounds, with the occasional human-made sniff or snort that was probably delivered by whatever actor was handy.
