It's 99% fake. Unit No. 8395 is Omni Allanon, Unit No. 8396 is (supposedly) Lucina, and Unit No. 8397 is another Lucina; Gumi rarely releases RS units that only have an Omni evolution, so it would've been more feasible for Unit No. 8397 and Unit No. 8399 to be the two different Omni Lucinas.

Also, although there are summons that start at 0:00 PST, the majority of Collaboration (and just any gate in general) start at 7:00 PST.

But good job Lin, you had me fooled for a few minutes :) I'm just surprised by the amount of work put into this. Like, creating two entire pieces of unit art, Lin must've had a lot of free time.
