Thing is don't think they retconned any thing cause the other kids where kids younger then Davis and the other so parents might be protecting them the agentcy thing that young gennai help and told adults bout chosen children fact most 02 ant retconned means non of it retconned even down to the fat takeru.and hikari have there.d3 digivice.not there original ones

I don't think so I can think there hurt cause I can confirm T.K and Kairi have there season 2 D-3 Digivice

I recall that in Zero 2, Gennai gave all the old guard some sort of power up that let them reach Ultimate, but then most of them, save Gabumon and Agumon, gave it up to Imperialdramon to unfreeze him from SkullSatanmon's attack and let it digivolve to Fighter mode.

Or in short, because they're the main two, and Digimon is known for that bullshit.

^This. I basically felt this while watching.

Also people found daisuke name in database of tri website so we might see them show up and tell other more bout alphamon cause so fare they are the only one with the data

Yet another reason Tamers is best Digimon.:D

I did the thing.

It was a little jarring for me, too, but I adjusted quickly.
And don't worry. I'm pretty certain they're just knocked out. I highly doubt that the 02 cast is dead. It would be incredibly insulting to their fanbase.

Except that they did. The events in this series contradict some established concepts from 02, such as Digimon being public knowledge, people from all over the planet possessing their own partners (With the Digidestined knowing this), and some other things that I probably forgot since I treat 02 like a fever dream.
This doesn't have much to do with the agency, but how our protagonists acted, treating the scenario as if they 8 are the only ones on the planet who can help, despite there being hundreds of other people and Digimon partners around.

I do not recall that, but everything about Imperialdramon is fucking stupid, so I don't doubt that it happened anyway...

Speak the truth! Spread the word!

Ok let say it did and these events fit more with there career paths of epilouge and tri just focus them. At the same time I do see 02 cast showing up at some point to be senerio of we got beat we scared we leaving it up to you senpai kinf of thing atsame time they would of info on alphamon

From the wiki, as I don't have the time right now to go back to the episode itself.

"Imperialdramon Fighter Mode is an alternate form of Imperialdramon Dragon Mode. The Fighter Mode gives Imperialdramon Dragon Mode a more human shape. It is also said that his fighting power is tripled.

This form was first achieved in Episode 43 of Digimon Adventure 02. When the evil Digimon Daemon and its Daemon Corps appeared, Imperialdramon Dragon Mode was frozen by SkullSatamon. To free Imperialdramon Dragon Mode, the Digimon of the older DigiDestined dedigivolved from their Ultimate forms and gave their remaining power to Imperialdramon Dragon Mode, triggering the Mode Change."

If you hate Imperialdramon, good for you. I don't see a reason why the season 2 cast should settle on having a lead Digimon be weaker than Omnimon, so I never had a problem with him. I did take issue with everyone else giving up what power they had just gotten back to push him to a vague, better optimized Mega form, but that's more to do with the writers shafting other characters than a fault I have with Imperialdramon itself.
