Anime
Tactimon is a soldier Digimon who possesses a peerless sword called "Jatetsufūjin-maru" (蛇鉄封神丸). Within Jatetsufūjin-maru is sealed a sinister power strong enough to split a star in two, so drawing this sword marks the collapse of a star. Therefore, Tactimon battles without drawing it, but even so, it exhibits the destructive force of its menace. Even more than his merit as a soldier, he excels in strategy with plans and tactics which are even said to be, "ingenuity itself, as if gushing forth like a spring," so his true competency is not in physical strength but in ingenuity. When he leads an army corps, it is said that, "the victory has been decided before he even fought." Due to the various plans he has laid out, when Tactimon stands upon the battlefield he has already guaranteed his absolute advantage.

As one of the Three Head Officers, nicknamed by as Tac- (タクちゃん), Tactimon oversees the progress of, , , ,  and. In the past, Tactimon's right hand warrior was, until his methods of dealing with the Magma Zone's inhabitants at the cost of his own soldiers caused Dorulumon to leave the group in disgust.

Tactimon formally introduces himself to Xros Heart when they appear in the Magma Zone, overseeing the execution of both Mikey Kudō and former underling Dorulumon. However, Blue Flare's interference distracts Tactimon, overpowering and  before they and Kiriha Aonuma fall back, long enough for Xros Heart to defeat AncientVolcamon and claim the Zone's Code Crown.

He next appears in the Forest Zone, to check on Kongoumon's progress in invading the Zone. He originally considered about giving Kongoumon "a severe punishment" for his "inneptitude" in invading the Forest Zone. However, since Kongoumon was "facing three humans with X Loaders", Tactimon decided to cut him a break. He sends Kongoumon to retrieve the Code Crown and the "".

Tactimon stays to face Mikey and the portion of the Xros Heart Digimon present. He manages to pummel and is about to destroy him when Dorulumon tackles him, saving X2. Mikey proceeds to DigiXros Shoutmon X2 with Dorulumon, and the  ( and the ) into. Shoutmon X4B duels Tactimon, who ultimately retreats but not before stating that the next time they meet, he will face them with his full power (even noting in a state of impressed shock, that at his current level, he couldn't continue fighting X4B).

Back at Bagra Army HQ, Tactimon requests to remove the seal on Jatetsufūjinmaru as he believes he cannot defeat Xros Heart without using his sword's true power. Despite the challenge, Tactimon shows great excitement towards the battles that are to come.

Shortly after when Xros Heart gets the final unclaimed Code Crown fragment in the Sword Zone, with Blue Flare also there, Tactimon makes his move on his foes. He applauds Mikey for finding the final Code Crown fragment. He also states his pleasure that Kiriha is there too as it will allow him to deal with both armies at the same time. He then proceeds to challenge Xros Heart and Blue Flare to a final battle for their combined Code Crown fragments. He then deploys the Digimon Xros Tower which seals the Zone off completely as well as cracks and corrodes the earth's surface. He then emerges from the Tower stating "This shall be the place of our total battle!" He also states "I hardly invaded any Zones just to wait for this day."

He then immediately after attacks them. While the others manage to hide in a crevice, Zenjirou Tsurugi is blown back by the force of the attack's power. Mikey and Kiriha form and  to fight back. However Kiriha wants to have DeckerGreymon take on Tactimon alone, while Mikey states they should work together instead of separately as Tactimon is a powerful and dangerous opponent. This proves true as Tactimon proceeds to nearly hurtle DeckerGreymon onto Kiriha and Mikey as well as strike Shoutmon X5 with two rapid attacks before the later can even defend himself. Akari Hinomoto asks in shock how he can be so powerful by himself. Nene Amano meanwhile confirms that they can't use Zone Travel after using her X Loader to attempt so, thus they can't escape from the battle. She convinces Kiriha to put aside his pride and work together with Mikey to defeat Tactimon. Zenjirou shows up from wherever he was blown back to, looking relatively unscathed by the attack. X5 and DeckerGreymon launch a combined attack against Tactimon, however they do little to no damage against him. Tactimon states it was a good effort but not good enough to take him down. During his next attack, Tactimon reveals to Xros Heart and Blue Flare that his sword was so powerful that Bagramon sealed it. He then proceeds to reveal that the seal was recently removed by Bagramon himself. He also reveals that his sword has the power to corrupt the data of Digimon who were killed in the when he summons demonic undead warriors to attack. His next attack is so powerful that it breaks apart both X5 and DeckerGreymon into their most basic components respectively.

Despite having defeated both X5 and DeckerGreymon, Tactimon acknowledges the armies to be worthy opponents and praises that they made him unseal his sword.

By stealing the alliance's fragments as they begin to reunite, while fending off Shoutmon X5 and DeckerGreymon. However, with help from Grademon's interference, Shoutmon X5B and Greymon manage to blast Tactimon away. When Bagramon uses his "Choujigen Storm" to steal the completed Code Crown, Tactimon is swept away into the Human World alongside Taiki, Akari, Zenjirou, and Shoutmon. Bent on revenge, Tactimon begins rampaging and takes Akari and Zenjirou captive in order to demand Taiki's X Loader. However, the tables are turned when Shoutmon digivolves to and destroys him.
