Grayox
- Grayox is a Beastformer from the Generation 1 continuity family.

Grayox (グレイオックス Gureiokkusu) was born to a family of knights in the service of the Bistoram Dynasty. An A-class knight himself, capable of fighting at full strength even in watery environments, he wields the mighty Oakron (オークロン Ōkuron) blade, which with a proper charge can cleave just about anything in two in a single blow. Grayox put the full weight of his incredible power, endurance and tenacity to serving White Leo, and was granted the title of Emperor of his homeland Petra under King Graysharp.
But he's so much more than mere muscle. Behind his stern and disciplined demeanor is a real Renaissance beast. Within him beats the heart of a poet, and he spends his time studying the natural sciences. He also serves as advisor to King Graysharp, listening to the news as the royal rhino gets it and carefully analyzing it. He lives a simple and frugal life when not in battle, greatly preferring to live in peace and quiet, but is always ready to leap into action without the slightest hesitation should White Leo ever call on him.

Toys
Transformers: Beastformers

- Grayox (Beastformer, 1987)
- Beast ID number: 10
- Accessories: Blade-weapon
- Part of the first series of Takara's Beastformers toys, Grayox is an anthropomorphic water buffalo with blue-green robotic armor. His left arm ends in a twin-horn claw. The rubsign on his chest reveals one of three symbols; Fire, Water or Wood.
- He was re-released in the subsequent second and third series; while the toy proper was not changed, the packaging and packed-in bio card was. The Series 1 release comes in a generic red-grid "Cybertron Beastformer" box, with a red-grid bio card with a painted character image on the front, though there was a random chance of his card being replaced by the rare "Holography Mirror" card. Series 2 came in a green-grid generic "Cybertron Beastformer" box, with the bio card putting the painted image on a jungle backdrop. Series 3's box was unchanged, but the bio card replaced the painted image with a simpler line-art image, first used in Hasbro's Battle Beasts cast poster. In the green-box releases, depending on the "Pack" he came in, there was a chance of his bio card being replaced with a rare "Secret Photo", "Bewitching Serpent Seal", or "VS Holography Mirror" card.
Beastformers
- Grayox (Beastformer, 1988)
- Beast ID number: 10
- Accessories: "Oakron" MVP Weapon
- Re-released in the Transformers-less Beastformers sequel series, Grayox was given a straight re-release with new packaging and a new, more filled-out bio card with corrected coloring. This new card also gave his weapon, now branded an "MVP Weapon", the name "Oakron" (オークロン Ōkuron).
- The initial early releases of this series had the chance for any Beastformer to have the rare Burstsun symbol; we'll probably never know if Grayox was ever actually one of them. Later in the run, the "mood ring" styled rubsigns were replaced with new rubsigns that revealed full-color Fire/Wood/Water images on black backdrops. (These rubsign variants also happened at the same time in the Hasbro Battle Beast version of the line.)
- Grayox (Gashapon/candy-toy Beastformer,
1988)- Meiji ID number: 27
- Accessories: "Devil Waver" weapon
- A small, super-deformed, articulation-free version of Grayox was seemingly intended to be sold as part of the Takara/Meiji candy toy assortment. A bio/data card matching the released candy-toy cards, with its own role-playing rules and using the Transformers-era painted character art, was released in packs of cards with candy, but the actual toy ultimately never saw release.
Notes
- Grayox's 1988 bio card gives him the nickname "Oak" (オーク Ōku).
