I was definitely hoping for and expecting VictoryGreymon and ZeedGarurumon given the mentioning of Yggdrasil and bringing in more of the Royal Knights given destroying Yggdrasil in the event that it goes out of control is what they were literally made to do. I was also hoping that, with more Royal Knights, we'd get more of the Seven Great Demon Lords while bringing back Daemon.
Sadly, the latter half of tri has just been a mess and rather than fix a number of plotholes made by Digimon Adventure 02, it just made more while also messing up other things, like reducing the Digimon Sovereigns to merely partners of a previous group of Chosen Children (never mentioned by Qinglongmon / Azulongmon) and thus destroying their mysticism, and also greatly dumbing them down given, with how strong Qinglongmon showed himself to be while still largely sealed by the Control Spires (effortlessly halting BlackWarGreymon), it only makes one wonder how they could lose to the Dark Masters when WarGreymon could one-shot two of them and MetalGarurumon one-shotting Pinnochimon / Puppetmon, leaving only Piedmon giving them any true difficulty overall. Even Apocalymon, the one who spawned them to begin with, was made to look like a joke once the group managed to recover and regroup from his initial attacks.
