 * An illusory cybernetic dragon monster used to trap the members of Gridman Alliance within a dream, each having befriended Akane. While Bujack influences on its victims, it was rendered intangible in real life until Gridman intruded through Grid Kinesis, ripping Bujack's wings to make it tangible and go on a rampage. The Neon Genesis Junior High Students then combine their Assist Weapon forms into Powered Zenon to quickly finish the monster off.


 * Anonymous (ナナシ)
 * Akane's final monster which she made at Alexis's urging, seemingly defeated by Full Powered Gridman. But Anonymous later sheds its skin to revealed a sinister embodiment of Akane's twisted will which slaughters the Poison Gas Monsters and defeats Full Powered Gridman. Anonymous nearly strangles Gridman to death when Anti intervenes with his new resolve to protect Gridman evolving him into Gridknight. With his new form, Anti reads through the monster's movements and destroy it.


 * Zegga (ゼッガー)
 * A gigantic ammonite-resembling monster that Alexis created from Akane using his Instance Abreaction on her, rampaging through the city before Gridknight appears and pulls out Akane from it before Alexis absorbed her. With no host, Zegga was left as an empty husk that rolled in Tsutsujidai before Gridman wiped it from existence with his Grid Fixer Beam.

SSSS Dynazenon
The Kaiju that appear are sought by the Kaiju Eugenicists, who seek to control them and use them to wipe mankind out. Upon being controlled by a Kaiju User's Instance Domination, they grew into red-eyed behemoths that towered over the cityscape, though Zaiohn grew massive without any outside influence.


 * Shalbandes (シャルバンデス)
 * The first monster to appear, controlled by the Kaiju Eugenicists off-screen. After failing to tame the monster with his own power, Gauma was forced to summon Dynazenon for the first time. He eventually defeats it with Dynarex formation.

 * Greyjhom (グレージョム)
 * A monster that was originally shorter and docile, until being manipulated by Juuga. Yomogi and Yume drag the monster into the air with Dyna Wing Combine so that Gauma can bombard it with Dynadiver's missiles.

 * Burnaddon (バーナドドン)

 * Manipulated by Mujina, it is a monster with the ability to temporarily transform three-dimensional objects into two-dimensional ones. It was destroyed by Dynarex's Rex Roar.


 * Neophobia (ネオフォビア)
 * A jellyfish-like monster with a hidden secondary mouth. It was manipulated by Sizumu from the water park and was destroyed by Dynarex.


 * Bullbind (ブルバイン)
 * A winged four-legged monster manipulated by the combined powers of Onija and Mujina. Although it came close to destroying Dynarex, Gridknight's appearance forced the Eugenicists to transport the monster elsewhere. During Bullbind's second rampage, it was killed by the combined force of Dynazenon and Gridknight.


 * Zaiohn (ザイオーン)
 * Originally a small monster which the Gauma Team discovered after it was abandoned by the Kaiju Eugenicists. The monster grew into a towering giant on its own and rampaged across the city, forcing Gridknight to destroy it using the Dynasoldier's Dynamic Cannon form.

 * Gibzorg (ギブゾーグ)
 * A monster that Juuga manipulated in the light of Yume's personal issues. It was defeated by the newly formed Kaiser Gridknight.


 * Garnix (ガルニクス)
 * The last stray monster to appear, it possessed a strange ability that trapped its victims in their own pasts, causing them to instantly vanish. It immediately caused the disappearance of the Kaiju Eugenicists when they attempted to control it, then caused the entire city to vanish bit by bit. With most of the pilots already taken by its effect, Yomogi was forced to travel through the space within it and bring the others back into the present so that they could fight. After rescuing his teammates and Knight, they formed Kaiser Gridknight and destroyed the monster.

Gridman Universe
Kaiju created by Mad Origin to aid his plans. Like Mad Origin, their names are close anagrams of Gridman's name.


 * Dimorgan (ディモルガン)
 * The first kaiju sent to Tsutsuji-dai by Mad Origin. It attacks with tentacles that emerge from projections on its back, shock waves from its mouth, and destructive rays from the crystalline body on its chest and arms.


 * Domgiran (ドムギラン)
 * The second kaiju sent to Tsutsuji-dai by Mad Origin. It is both agile and powerful, and has the potential to take on both Full Power Gridman and Kaiser Grid Knight at the same time. Its attacks include thunderbolts from its entire body, photoballs from both palms, and destructive rays from the tip of its tail, and when its hands are joined together, it releases an even larger beam.


 * Noir Dogma (ノワールドグマ)
 * The third kaiju created by Mad Origin in order to eliminate countless irregular beings that should not exist in the world. It is characterized by a hard shell that covers its entire body, and it shoots beams from an umbrella-shaped part on its head. Some of them can also fly in the sky.
