Let's play a jogress game

[The Krookodile Hunter]

Baihumon, white tiger.

([Agumon + Digimental of Light] + Lynxmon) + [(Gabumon + Digimental of Hope] + Stegomon) = ???mon

 

[Notus]

Agumon + Digimental of Light = Siesamon, holy beast, keeps the overall color scheme of Light's armors
Gabumon + Digimental of Hope = Moosemon, already an armor level and fits very well as a "equine Garurumon"

Siesamon + Lynxmon = Flaremon, divine fire lion
Moosemon + Stegomon = Dorugremon, beastial dragon with metal wings

Flaremon + Dorugremon = Bryweludramon - Dorugremon metallic parts become the armor and gives overall shape, while Flaremon provides the flames


Andiramon + Peacockmon = ?

 

[McGann]

Andiramon + Peacockmon = Dianamon
A blue armoured rabbit.

Hubmon + Digimental of Knowledge = A
Aequecedramon + Digimental of Sincerity = B
Pulsemon + Digimental of Reliability = C
Morphomon + Digimental of Friendship = D

Gattai A B C D in any combination.

 

[Notus]

Hubmon + Digimental of Knowledge = SandYanmamon - insect with similar color
Aequecedramon + Digimental of Sincerity = Coredramon (Green) - dragon related to earth
Pulsemon + Digimental of Reliability = Seadramon - lightning wielding sea mon
Morphomon + Digimental of Friendship = BladeKuwagamon - armored electric "insect"

Yanmamon + BladeKuwagamon = Cannonbeemon - cyborg insect
Coredramon + Seadramon = Majiramon - eastern dragon

Cannonbeemon + Majiramon = Metallicdramon - robotic sky/heaven dragon

Next:
Majiramon + Aegiochusmon: Holy = ?

 

[IamTheSovereign]

Majiramon + Aegiochusmon Holy = Goldramon, a dragon with the holy element and color scheme of Aegio

Centarumon + Garurumon = ?

 

[McGann]

Centarumon + Garurumon = Beowolfmon/WereGarurumon: Sagittarius Mode
A cyborg wolfman with long rage artillery.
or
Centarumon + Garurumon = Cerberusmon
A canine with routes in Greek mythology. (EDIT: Wait... Sagittarius was a Greek Centaur too... was that the thing?)

App Gattai
Aequcedramon, Ganvivormon, Ririmon, Pyantomon (All Rookies, any combination order).

 

[The Krookodile Hunter]

Aequcedramon + Rurimon = Paledramon
Ganvivormon + Pyontomon = Meicoomon
Paledramon + Meicoomon = IceLeomon


ExVeemon + GeoGreymon + Shoutmon X2 + DoGatchmon

(In no particular order)

 

[Notus]

GeoGreymon + Shoutmon X2 = MetalGreymon (XW)
ExVeemon + DoGatchmon = Cyberdramon

MetalGreymon (XW) + Cyberdramon = Darkdramon


Sandiramon + GrapLeomon = ?

 

[The Krookodile Hunter]

Baihumon, big cat with East Asian flair. Also Wikimon says both Sandiramon and GrapLeomon can Digivolve into it.

App Gattai

Agumon (original) + Labramon + Falcomon (original) + Kunemon + Floramon + Lopmon + Dracmon + Syakomon

 

[McGann]

Falcomon + Lopmon = Turuiemon
Agumon + Floramon = Parasaurmon
Labramon + Kunemon = Panbachimon
Dracmon + Syakomon = Gesomon

Gesomon + Parasaurmon = Blossomon
Panbachimon + Turuiemon = Pandamon

Pandamon + Blossomon = Rosemon: Burst Mode

Zubamon + Ludomon = ?

 

[Notus]

Zubamon + Ludomon = Bootmon - attack + defense = support, his coloring works as if Zubamon's was darkened by Ludomon's and the turbines are somewhat invokative of shields

Indramon + WereGarurumon (Black) = ?

 

[citramon]

Zubamon + Ludomon = Bootmon - attack + defense = support, his coloring works as if Zubamon's was darkened by Ludomon's and the turbines are somewhat invokative of shields

Indramon + WereGarurumon (Black) = ?

Since hindu devas are equivalent to the greek theoi, I'm inclined to say that Indra + black werewolf = Plutomon, but something in my mind is screaming Sleipmon.

Dorbickmon + Venom Vamdemon =

 

[Notus]

Dorbickmon + VenomVamdemon = Death-X-Dorugoramon, beastial undead dragon

Pajiramon + Orochimon = ?

 

[McGann]

Pajiramon + Orochimon = Hadesmon
A quadropedal white dragon.
Goat imagery is somewhat linked to hell, and Revivemon had multiple heads too.

Mitamamon + Kentaurosmon = ?

 

[The Krookodile Hunter]

Fanglongmon seems to work as a fusion of two Mega level mythical beasts

Bulkmon plus SkullKnightmon

 

[Notus]

Bulkmon + SkullKnightmon = BlackMegaloGrowmon, armored dark dragon

Makuramon + Hangyomon = ?

 

[The Krookodile Hunter]

Poseidomon, humanoid sea god

Etemon + Garudamon

 

[McGann]

The obvious answer feels like Phoenixmon since it has an ape-like body.
Crossmon kind of works if you have the dormant King data play a role. Also, both he and Etemon were landmark evolution enemies for Tai and Greymon.

Etemon + Garudamon = Crossmon

In that vein: Myotismon + CanonBeemon = ?

 

[The Krookodile Hunter]

Beelzemon X, winged demon with guns and x-antibody

SkullScorpiomon + Digitamamon

 

[Notus]

SkullScorpiomon + Digitamamon = Deathmon, undeath + life (egg); Digitamamon's "spectre" posseses and gives flesh to Scorpiomon

Sinduramon + Angewomon = ?
