I noticed that as well, although I think it is used in the episode with Ace (Episode 19).Cryptid_Liker wrote: ↑Sat Dec 19, 2020 6:31 pm ^There's a bunch of things they introduced and dropped. For an example, Zett only used the Z Lance Arrow twice and none of those instances were after episode 10.
The devil splinters plotline also gets dropped. Although to be honest, I'm fine with that since I was concerned they were going to just do another Belial revival - the show did have both Ultraman Zero and Geed in it.
