Dodon was the 42nd Monster of the week in order of appearance to fight Jeeg in Ep.37 of the Kotetsu Jeeg Anime; it was a humanoid type Robot Beast with a dark Green torso an Pelvis, with Lavender (upper) and orange (lower) legs, with Green Arms; the Head was Green adorn with spikes on top and orange colored Mouth Plate; its eyes were purple.

Its major combat abilities and weapons were its fighting skills, a curved double bladed battle ax and spew fire from the Mouth plate.

Picking up from the events from their last battle (and while been spied by Don and Pancho in the Background) Hiroshi thinks of Flora motives, believing her to still be human inside, when he is suddenly lured by hallucinations of her. Later, running back to Build Base, Hiroshi finds Michi, who he convinces her to fly him to Jamatai to talk to Flora – much to the latter's disbelief and the two take the Big Shooter, ignoring the calls from the Base (along the way they see MechaDon2 swimming in the same direction, which is briefly attack by a Giant Shark .... Okay?). Unbeknownst to all, Hiroshi is been lured into a trap by Emperor Dragon, using Flora's remote Hypnosis – Ikima and Amaso are deployed to wait for the enemy while Flora begs to join in and kill Hiroshi, though Dragon rejects this and reminds her once more to ignore her feelings, as it was he who brought her back from the dead.

As the Big Shooter arrives, they are attacked by the Orochi Fortress (piloted by Ikima and Amaso). In their scuffle, the Fortress crashes into a mountain, and Hiroshi comes out demanding Flora to come out, only to be fired upon by the Orochi heads. Hiroshi requests the Earth parts and assembles into Earth Mode Jeeg, but is distracted by Flora when the Fortress pushes him into th Crater, the vessel been used to plug the crater.

Jeeg sees Flora on the other side of the lava pit and tries to talk her into joining his side, understanding her situation, but pressured by Dragon, she presses a detonation device under Jeeg, causing him to fall into the Lava Pit. Jeeg tries to climb the wall, still talking to Flora when Dodon breaks through the rock, pushing the mecha back into the Lava. Dodon spent much of this encounter making sure Jeeg doesn't get out of the Lava Pit. Above, the Big Shooter tries to move the Fortress when the MechaDon2 arrives in a charge attack, holding a (giant) stack of Dynamite - the attack fails and the MechaDon2 gets captured by the Fortress in the process. Jeeg escapes the trap by impaling Dodon with a Drill Missile, though the Monster still functions; the Mecha digs its way toward Flora's Chamber, were its captured by Roots and Vines. Dodon appears to finish the job.

The Build Capsule then arrives and joins the Battle by latching magnetic disks onto the Orochi fortress and lifts it out of the crater – in the meantime Prof. Shiba puts sense in Hiroshi and tells him to escape. The Capsule let's go of the fortress, it ramming through the hull with a Spin attack, allowing the MechaDon2 to be drop and been caught by Magnetic Waves from the vessel; Michi fires at the Fortress as it crashes. Hiroshi then fire Jeeg Beam on the Monster blasting its arm off – with the whole Plan going South, Dragon orders Flora to kill Jeeg with a special Crystal explosive he device, much to her hesitancy – Jeeg uses Spin Storm to dispose of Dodon, the blast of the Monster's destruction breaking him free from the roots.

He then sees Flora again, and Jeeg tries to convince her one more time to join him, seeing there is still warmth and humanity in her – despite this and her hesitancy, she throws the Bomb at Jeeg; it explodes, Flora caught in the blast, but the Mecha escapes. Flora asks forgiveness from Dragon, who berates her for her failure. Orochi then returns to block the Crater, but Jeeg drills through the Fortress, layer by layer; the vessel explodes and roles down the mountain.

Jeeg then stands looking at the site, thinking Flora couldn't kill him due to her emotions, hoping for her she can understand once more Human Feelings, awaiting for a time of peace without war.
