Card Appearances:Elemental HERO Terra Firma

Yu-Gi-Oh! GX[]

This card is Jaden Yuki's signature card in the Yu-Gi-Oh! GX manga series. He inherited this card from Koyo Hibiki.
When "Elemental Hero Terra Firma" uses its effect, it becomes known as "Terra Firma Magma", and its powered-up attack is called "Magma Slash".

In chapter 1, Jaden uses this card during his duel against Mr. Ryuga. He Fusion Summons this card during Ryuga's turn by using "Alternate Fusion" to fuse the listed materials on his field and in his hand. In the resulting replay, "Cyber Dinosaur", whose ATK had been halved from "Swamp of the Fallen", is forced to attack this card and be destroyed. Jaden then activates "Shield Strike", inflicting damage to Ryuga equal to this card's DEF and winning the duel.

In chapter 3, Jaden uses this card during his duel against Chazz Princeton. He Fusion Summons this card using "Polymerization", then activates this card's effect, Tributing "Elemental Hero Stratos" to gain ATK equal to the latter's ATK. This card then attacks and destroys Chazz's "Dragonic Knight". After the Damage Step, Chazz activates "Reverse-Time", banishing this card and returning the field to its state at the start of the turn.

In chapter 5, Jaden uses this card during his duel against Bastion Misawa. He Fusion Summons this card during Bastion's turn by using "Soul Fusion" to pay 1000 Life Points and banish the listed materials from his Graveyard. Jaden then plays "Terra Firma Gravity" to switch Bastion's "Rigrass Leever" and "Fox Fire" to Attack Position and attack this card, winning Jaden the Duel.

In chapter 6, Jaden uses this card during his duel against Alexis Rhodes. He Fusion Summons this card using "Polymerization". In the following chapter, Alexis activates "Cold Fusion" to destroy this card and Special Summon this card's Fusion Material Monsters back onto the field.

In chapter 14, during a flashback, Koyo uses this card during his duel against Jaden. He Fusion Summons this card using "Parallel World Fusion", to return the listed materials, that were banished, to Koyo's deck. Koyo then activates this card's effect, Tributing "Elemental Hero Stratos" to gain ATK equal to the latter's ATK. This card then attacks and destroys "Elemental Hero Thunder Giant", winning Koyo the Duel.

In chapter 21, Jaden uses this card during his duel against Seika Kohinata. During Seika's turn, Jaden activates his face-down "Master Magician's Incantation", allowing him to activate "Polymerization" from his hand and Fusion Summon this card in Defense Position. In the resulting replay, Seika's "Evil Dragon Ananta" attacks and destroys this card. On Jaden's next turn, he banishes this card, "Thunder King Rai-Oh" and "Elemental Hero Stratos" from his Graveyard as part of the effect of "Alchemical Experiment".

This card is mentioned by David Rabb shortly after he defeats Alexis Rhodes in chapter 24, and before he watches Jaden's rematch with Bastion in chapter 27.
In chapter 28, Jaden uses this card during his rematch with Bastion. Using "Fusion Birth", he mills the top five cards of his Deck, and because the listed materials are among the milled cards, Jaden is able to Fusion Summon this card using "Fusion Birth's" other effect. It attacks and destroys Bastion's "Gozuki". On Bastion's turn, he uses the effect of "Kasha" to return this card to Jaden's Fusion Deck.

In chapter 33, Jaden uses this card during his rematch with Chazz. He Fusion Summons this card using "Parallel World Fusion", to return the listed materials, that were banished, to Jaden's deck. In the following chapter, it attacks and destroys Chazz's "Light End Dragon" (whose ATK was 2100). On Chazz's next turn, Jaden activates "Terra Firma Gravity", forcing Chazz's "Dynamite Dragon" and "Red Wyrm" to switch to Attack Position and attack this card; both are destroyed. "Dynamite Dragon's" effect then activates, reducing this card's ATK by 300. On Chazz's next turn (Turn 10 of the duel), Chazz summons "Light and Darkness Dragon" and has it attack and destroy this card.

In chapter 40, Jaden uses this card during his duel against Reggie MacKenzie. He Fusion Summons this card using "Miracle Fusion", banishing the listed materials from his Graveyard. Jaden then activates this card's effect, Tributing "Elemental Hero Voltic" to gain 1000 ATK. This card then attacks Reggie's "Iofiel". However, in the next chapter, Reggie activates the effect of "Heaven's Judgment", sending "The Splendid Venus" from her Deck to the Graveyard to destroy this card.

In chapter 60, the possessed Atticus Rhodes steals this card from Jaden, along with "Winged Kuriboh", for Tragoedia.

In chapter 61, Tragoedia returns this card and "Winged Kuriboh" to Jaden after restoring his body using the power of the Legendary Planets.

In chapter 64, Jaden uses this card during his duel with Chazz Princeton against Tragoedia. He Fusion Summons this card using "Miracle Fusion" that was activated by the effect of "Ma'at". Jaden then activates this card's effect, Tributing "Elemental Hero Gaia", which had 4200 ATK at the time, to increase its own ATK to 6700. It then attacks and destroys Tragoedia's "The Supremacy Sun".

In Special One-Shot, Koyo uses this card during his duel against Jaden. On the first turn, he Fusion Summons this card using "Polymerization". On Jaden's turn, his "Masked HERO Divine Wind" attacks this card, but Koyo activates "Element Counter" to negate the attack and inflict 1000 damage on Jaden (500 for each "Elemental HERO" in Koyo's GY). On Jaden's next turn, his "Masked HERO Koga" attacks this card; Koyo activates "Higher Dimension Guard", banishing "Elemental HERO Gaia" from his Graveyard to prevent this card's destruction by battle this turn. Jaden's "Masked HERO Anki" then attacks this card, followed by "Divine Wind", both dealing damage to Koyo. On Jaden's next turn, Koyo activates his set "Element Fusion", allowing him to Fusion Summon using this card as material if two other materials are banished. He thus Fusion Summons "Elemental HERO Core" by sending this card to the Graveyard.
