Guilmon's chest is emblazoned with the Digital Hazard symbol; the symbol did not appear on the original sketch of Guilmon that Takato used to create him, but did show up on other pages.
Guilmon is a virus-type Digimon, though his attitude and kindness most of the time could lead to thinking that he was a data or even a vaccine-type. Guilmon's fighting style, in which he gives in to his bestial nature, exhibits his viral nature, as he fights with much more zeal and ferocity than Agumon or other Digimon protagonists, as his partner, Takato Matsuki, intended on when he came up with Guilmon.
Though he doesn't look it, Guilmon is normally playful and friendly, proving to be quite popular with Takato's classmates for being a real live Digimon. Despite being portrayed as childlike, Guilmon occasionally shows deep insight. For example, when Takato didn't want Guilmon to digivolve, in fear that Guilmon would no longer be the same, Guilmon pointed out that Takato has changed over time as well, but he is still the same person.
Guilmon gets along very well with Terriermon and Calumon, but his first meeting with Renamon was as enemies. Guilmon later acknowledges Renamon's knack for "being right" in combat situations . Guilmon would either ignore Impmon or try to play with him.
At first, Guilmon wasn't very good at listening to Takato, always breaking out of his cage, and fighting Renamon when Takato told him not to. Guilmon admired Takato's determination after he worked frantically to reverse Guilmon's first digivolution, and has since obeyed Takato's every word.
In the Japanese version, Guilmon has a habit of speaking in third person. This includes referring to others by their name rather than "you" and referring to himself in third-person tone. He mostly seems to alternate between this and the use of pronouns throughout the series, although he typically only does this as Guilmon and Growlmon. He also stops his "Takatomon" habit much earlier in this version, though he continues doing it a little bit throughout the rest of the English version.
Guilmon is a curious and naive Digimon, the youngest of the partner Digimon, and also has a strong love for bread. He is extremely powerful for a Rookie, and is able to injure or defeat Champion and Ultimate Digimon that higher-level Digimon have trouble with. Guilmon is literally thick-skinned and thickheaded, giving him substantial protection from enemy attacks, and making his headbutts deadly.
Guilmon was created from Takato's drawings of Guilmon, and brought to life by the mysterious Blue Card. At first, Guilmon had not been aware of the differences between humans and Digimon, calling his partner Tamer "Takatomon".
- Pyro Sphere (Fireball): Guilmon spits a concentrated blast of fire from his mouth.
- Rock Breaker: Guilmon hits his opponent with a huge amount of force, almost like he is throwing a rock at his opponent.

He speaks in the same manner as in Tamers and even refers to himself in the plural as a definite shout out.
Digimon Xros Wars (manga)
Digimon Xros Wars: Super Digica Taisen
The name "Guilmon" refers to only the Rookie form of this digimon. Throughout the series, Guilmon gains the ability to digivolve into a number of more powerful forms (each with a different name). The rookie form, however, is his most common and preferred form.
While in Ryo Akiyama's party, Guilmon will degenerate to Jyarimon when his YP depletes.
Gigimon is Guilmon's In-Training form.
Growlmon is the Digivolved form of Guilmon. Guilmon first digivolved to Growlmon during his fight against Devidramon . In this new form, Growlmon fought a fierce battle against the dark dragon and ultimately destroyed him with his Pyro Blaster attack. He is also ticklish.
Afterwards, Growlmon discovered that he wasn't able to regress Takato tried various methods to make Growlmon use up his "surplus" energy, but failed. Growlmon eventually did De-Digivolve naturally after observing a rainbow with Takato. After a few more times of digivolution, Guilmon does learn how to de-digivolve. Growlmon fights the Deva Mihiramon, but fails until Takato uses a Blue Card to Matrix Digivolve him to WarGrowlmon. He later battles Sandiramon and Sindarumon and destroys them both with help from the others. He appears to battle the other Devas, but his attacks prove pretty much useless against them..
In the battle against Beelzemon, Growlmon was at first shocked that Leomon had been killed so coldly, and reacted by reverting to his feral instincts, which ultimately culminated in digivolving to Megidramon.
When Locomon attacks, he tries and fails to stop the rampaging Digimon.
WarGrowlmon is Guilmon's Ultimate form. WarGrowlmon first appeared when Mihiramon of the Devas appeared . Since Mihiramon was much stronger than other Digimon, Takato had to use a Blue Card. Slashing this card allowed Growlmon to Digivolve into WarGrowlmon, who was then able to defeat Mihiramon. Growlmon later digivolved again to defeat the Devas Indramon and Vikaralamon in the real world and to fight both Beelzemon and Zhuqiaomon in the Digital World. WarGrowlmon also fought against the D-Reaper when the tamers returned from the digital world, due to their temporary inability to bio-merge .
The first few times Growlmon Digivolved into WarGrowlmon, he and Takato were linked mentally. Takato declared the "Atomic Blaster" attack at the same time his Digimon was about to use the attack. Takato even made some of the same movements that WarGrowlmon did.
Megidramon is a Mega Digimon.
Megidramon is Guilmon's alternate Mega form when the full destructive power of the Digital Hazard is released Terriermon fell into one of these fissures while fighting Beelzemon. He was then saved by Renamon. Guilmon turned into Megidramon once when he Digivolved using Takato's anger. The death of Leomon at the hands of Beelzemon caused Takato to fill with blood lust. Jeri finally snapped him back to his senses and he became horrified by Guilmon's transformation, which also destroyed his D-Arc (D-Power in the English Dub)., and as a result, his existence endangered the very fabric of the digital world. Megidramon possesses acidic saliva, with The Hazard shown as the Digital Hazard symbol on its chest flashing red. The central triangle was permanently red, but the three triangles around also flashed red. Once this started, Henry realized that the symbol was a hazard and the ground under the groups feet started to crack and massive fissures were formed.
At first, Megidramon seemed to have the upper hand against Beelzemon and attempted to devour him. However, Beelzemon eventually won the battle by absorbing Makuramon's data along with Terriermon and Renamon's Ultimate data, beating Megidramon unconscious. Takato cried, knelt down by the unconscious Megidramon and wished that he and Guilmon could start over. But as soon as Takato realized that he couldn't give up the old Guilmon, Megidramon quickly changed back into Guilmon. When Beelzemon tried to shoot them, Guilmon instinctually summoned a phantom version of Megidramon's tail to knock the bullets away. Takato then wished that he and Guilmon could fight Beelzemon together as it should be. This resulted in him Biomerging with Guilmon to become Gallantmon. After the battle, Takato then received a new D-Arc, an Ultimate (Golden) D-Arc. Takato was the only one in the season to get a Golden D-Arc.
Gallantmon is the true Mega form of Guilmon. Gallantmon was the first Biomerged Digimon to appear. Gallantmon first appeared when Takato Biomerged with Guilmon in order to fight Beelzemon. In this new form, Gallantmon was able to defeat Beelzemon. He also destroyed Caturamon during the battle, but it was Beelzemon who absorbed his data. Gallantmon's power proved a major asset in the battle against the D-Reaper. Gallantmon played a key role in confronting the D-Reaper and in obtaining the ARMS "Grani" as his mode of transportation.
In the English version he often speaks with a merged voice between Guilmon and Takato, representing that he is a fused dual entity of the two both physically and mentally and often retains the childish mentality of Guilmon in part. Whereas in the Japanese, he speaks with a single voice (Takato can speak separately, though) and is much more 'mature' in mindset, speaks in a refined manner, often referring to himself by saying "I, Dukemon" and Takato even refers to him internally as Dukemon (however he does refer to him internally as Guilmon just before they split apart from being Gallantmon Crimson Mode). He can even be hotblooded in battle, particularly when he defeats Beelzemon.
Gallantmon X is an alternate mega form for Guilmon.
Gallantmon Crimson Mode
Gallantmon Crimson Mode is the mode form of Gallantmon. Gallantmon had found himself overwhelmed in his battle against the D-Reaper. In his time of need, Grani gave the last of his power to Gallantmon triggering a mode change. In his newly digivolved form, Gallantmon gained wings and newly mended crimson armor, wielding a sword “Blutgang” in one hand and spear “Gungnir” in the other. While in mode form, the Digital Hazard within Gallantmon's Digicore is fully sealed, enabling Gallantmon to unveil his full potential. Even with this newfound power, Gallantmon Crimson Mode was unable to defeat the D-Reaper's Agent-01. Agent-01 destroys his weapons after he easily destroys many other agents and knocks him into the Mother Reaper causing him to start to delete. Gallantmon Crimson Mode pulls himself together, flies out and punches his fist through Agent-01 destroying it. He goes on to attempt to rescue Jeri and Calumon but due to an error in the Red Card's effects due to Shibumi not taking into account the Digimon/Human hybrid he de-digivolves back into Takato and Guilmon before he can succeed.
During the final battle with the Parasimon, Gallantmon and his allies are outnumbered and being overwhelmed. Takato's determination to win causes Gallantmon to tap into the power that Grani gave him and Mode Change into Crimson Mode. Gallantmon Crimson Mode is able to easily destroy all the Parasimon in one shot with his Crimson Light attack ending the invasion and saving the Earth. This is Guilmon's most powerful form and likely the most powerful Digimon in Digimon Tamers, (probably) excluding the Digimon Sovereigns.
