I'm sorry but I have to get this all out. I have to release my frustration on this.
Devimon is the first arc antagonist here, like in Adventure 01. He is actually more menacing than his Adventure 01 counterpart, though he seems to serve under Negamon, the third arc antagonist. For the epic fight with him, he turns into two One-Winged Angel (how ironic) forms - NeoDevimon, and then DoneDevimon (or was it DanDevimon?), who was a mindless beast, which, like Kid Buu or Dark Beast Ganon, gives "This is the last fight with him, his end is near" vibes. And then WarGreymon destroys him in an EXTREMELY spectacular fashion.
That should have been the end of it, but inside Sakkakumon, what appears to be the Devimon clone is actually revealed to be the real Devimon, respawning here and revealing that he is the manifestation of Patamon/Angemon's despair split off from him, and thus cannot truly die. (And I rewatched that episode a few times to try to make ANY case for it being a different Devimon, for his despair taking that form for some reason, it being a clone, etc., but every time I came to the same conclusion: It is the very same Devimon.) In the end all that can be done is him going back inside Angemon, no longer being a threat, and later reforming during the final fight with Negamon.
Now, don't get me wrong. The twist I feel could have worked, and the idea of a reformed Devimon is interesting, plus they'd already had his Adventure 01 counterpart stay evil to the end and die permanently so it's a new twist.
But, being a retcon to what we thought was his final end as DanDevimon... I feel both events ruin each other. Either one on its own would be pretty cool, but both together, just don't work. His return completely takes away from the epicness of his One-Winged Angel battles and spectacular death scene, these kinda fake-outs really bug me, and said retcon makes the twist and his redemption taste terrible.
I feel, if they wanted to do that twist, they should have done it at the end of the actual fight with him, not after that fight ended in spectacular fashion.
Does anyone else kinda feel this way?
