Thor and Svarog. Subverted in that they actually are gods to begin with, so more a statement than a boast... even if they do get quite boast-y about it.
And then Tyr, Dunk and Azur, being descended from them are apparently partly gods too.
Big Brother Instinct: Azur to Dunk, despite being the younger brother. Bedivere to Guinier, also despite being younger. Pyra to Maximus, for the female variation.
Cain and Abel: Possibly. In the midst of Samael's ranting prior to his fight with Sha, he -implies- that he is the Digimon equivalent of the bibilical Cain 'the first to murder for murder's sake'. This is reinforced by his surname, and Michael explains some of Samael's past which adds to the allusion. If this is the case, and quite possibly anyway, Samael and his brother fit this trope. On a lesser level, Michael and Samael act like this on occasion, mostly when Samael pulls a Face Heel Turn and joins the Royal Knights.
Calling Your Attacks: It's Digimon, so naturally they do. There are also the Digivolution Chants, but see Invocation.
Dark Is Evil: Samael's darkness and demonic nature comes to the surface when he turns against the Peacemakers
Dark Is Not Evil: ...and yet he returns to their side when he realizes that his darkness has only grown.
Doomed Hometown: Kheprius and Barachiel's village was massacred by a group of MetalTyrannomon X.
Proud Warrior Race Guy: Thor and Svarog, as gods are almost defined by this. Many other gods also fit the bill.
Hero Antagonist: The Peacemakers. Lampshaded on one occasion by Caradoc when he comments on them being a 'bunch of misfits'.
Howl of Sorrow: Azur, when Pyra was dying. And Dunk when Azur was wounded by Bors.
Immortal Immaturity: Neither Thor nor Svarog act like you would expect 1000 and 2000 year old immortal gods to act. In fact, many gods possess this quality... others, however, do not.
In Harmony with Nature: Thor repeatedly seeks enlightenment and answers by removing himself to isolated pockets in the wilderness or away from civilization.
Infinity +1 Sword: The Black Sword serves this for both Artorius and Bedivere. To a degree the White Sword plus Initialize does this for Thor.
Invocation: Several characters have digivolution chants as a means of centering their focus.
Knight Templar: The Royal Knights, as revealed in Devil's Ascent, they were acting to stop Mephistopheles by eliminating 'the Cambion', a group of Tamers who serve as Mephistopheles' 'Digidestined/Chosen Children' in effect, though their role in the grand plan is currently unknown. More specifically, Constantine, who is a literal knight templar, to the point his species is SaintTemplarmon.
Light Is Not Good: The Royal Knights, champions of order and honor play the role of the antagonists driven mad by their quest.
During the naming of the Peacemakers, Loki suggests 'The Avengers' and 'Warbound' for the newly formed group. Both were names given to the main group in Civil War and Dark Reign.
A recurring pair of guards in Avalon are a Ravemon and Golden Rapidmon, a reference to Hotshot's characters Karasu and Rai in Civil War and Dark Reign.
During the Siege, Samael is sent to infiltrate Avalon through the sewer system. He Lampshades that a plan that involves going through the sewers is doomed to fail. This is a reference to Civil War, in which the Avengers used the sewers to infiltrate the Dramon Empire. The plan failed horribly due to information given by The Mole.
Also during the siege, there are several digimon tasked with protecting the Tamers. Amomg them are a Zudomon, a Spinomon, a Justimon, a Rosemon and a few others. They are all species of members of the Avengers.
"Not So Different" Remark: Sir Cador tells Kheprius that he isn't so different from himself, especially in their views of doing things for the greater good.
Norse Mythology gets many, given that Thor is the Digimon equivalent of, well, Thor. Asgard appears several times, and Odin is frequently mentioned as a heroic figure in the Digital World backstory. Tyr and Tiwaz both derive their given names from Norse mythology. Tyr (whose namesake, in legend, has his right hand bitten off by the wolf Fenrir) also loses his hand in a beam blast caused by the Chaos Lord, Typhon. Arthurian Mythology also gets several, the Royal Knights are named for Arthurian characters, as are Bedivere, Caradoc and Guinier. Marvel Comics gets one in the form of Fandral, Hogun and Volstagg - and Word of God says some scenes involving Volstagg in particular are inspired by his scenes in the comics.
The first three Tamers encountered have GrapLeomon, Andromon and Orochimon as partners, a reference to the Digimon Tamers episode 'Kazu's Upgrade'.
Tiwaz's goggles are a reference to all the previous Digimon seasons (barring Digimon Data Squad), which has the leaders wearing goggles, along with an inadvertant reference to Legendz, which also features an aviation goggle-wearing dragon known as Shiron. Tiwaz and Fenrir's rivalry is also something of a reference to Digimon's "leader versus lone wolf" dynamic which is often present.
"Well Done, Son" Guy: Thor, Tyr. Pyra counts, but is female. Caradoc used to be this.
