If I may throw my considerations into the hat ring, Space Cyberdramon(Read 2010 Cyberdramon, Read Xross Wars Cyberdramon) does seem kind of fitting to Beelzemon. Especially because its default depiction in either form is a murder machine, not a justice seeker. (As far as I can tell, the only reason it even Digivolves to Justimon is because of Ryo, literally in this case, since Biomerge was the thing at the time. That and his Monodramon was somehow actually Millenniummon too somehow or something. So... yeah.)
