Digimon World: Next Order
KaiserGreymon is a Fire Neutral type, Mega level Digimon. It digivolves from MetalGreymon, WarGrowlmon and Agunimon and can DNA Digivolve with MagnaGarurumon to Susanoomon. Mega level Digimon can't poop but if Piedmon's experiment maxes the poop gauge, it will digivolve into PlatinumSukamon or Sukamon.

KaiserGreymon is found in Server Desert. KaiserGreymon introduces itself as "EmperorGreymon" when meeting Takuto/Shiki but despite this, its name is KaiserGreymon in all other instances. KaiserGreymon is trying to accumulate massive amounts of energy, though doesn't state why, and its comrade, MagnaGarurumon is out collecting energy but KaiserGreymon fears that it wont be enough. After the tamer agrees to help, Kaiser is shocked and claims they must be a special type of human. After trusting them, it states that they are collecting energy so that they can revive their master, Susanoomon. They require Fire, Light, Ice, Wind, Lightning, Dark, Earth, Wood, Water and Steel energy though the duo already posses all but Wood, Wind, Earth, Steel and Dark. It sends the tamer to collect ivy from the Palace of Thorns but has to be harvested before noon, or else it wont be there to cover the Wood, a Speed Chip to cover the Wind and needs to siphon the energy of a Digimon with more than 8,000 HP for Earth Energy, though the Digimon is unaffected by the process. KaiserGreymon than sends the tamer to find MagnaGarurumon as he is running late, so must have found trouble whilst collecting the other energy. MagnaGarurumon is found in the Infinite Cauldron. MagnaGarurumon also refers to Kaiser as "EmporerGreymon". The tamer informs MagnaGarurumon of the situation, so Magna agrees to trust the tamer. MagnaGarurumon has the Steel and Dark energy provided but is struggling to transport it so has the tamer take 10 Supermassive Machine Parts labelled A through J to give to KaiserGreymon to act as the Steel energy. After transporting it the tamer then has to transfer the Dark energy to KaiserGreymon in the form of a supermassive dark matter, which despite the name is very small but has vast amounts of high compressed energy. MagnaGaurumon has 40 of these, though only has the tamer carry 20 of them, carrying the rest itself to take to KaiserGreymon. They then return to KaiserGreymon, combine all the energy together, which frees Susanooomon. The two of them then join the City as thanks. They both work in the arcade, KasierGreymon during the day and MagnaGaururmon during the night and swap coins for a choice of two different materials, a Stone or Wood material from KasierGreymon or a Liqiud or Steel item from MagnaGarurumon once a day, however the second option is glitched and can be selected over and over, never actually doing the trade, meaning only the first option can ever be chosen by both Digimon.
