As we all know, Zero Legends is a part of the most unimportant bits of the game [Socrates doesn't count], and with it comes many problems, such as the first stage featuring that green beak bird that i'm sure that @Chara-herra is familiar with, the cyclones appearing as bosses in certain subchapters, adding CAT GOD HIMSELF AND BAKOO to ZL, PONOS giving us a stupidly pointless true form [Meta-Shittybuster], lil divine cyclone being a thing and of course, Socrates as one of the first legend bosses of ZL.
So, i'm going to say some predictions that i have for the future of ZL. [May be innaccurate because i'm at a SoL subchapter after Walk of Fame-]
1. Number of Subchapters
One thing that is good to notice is that both SoL and UL have a thing in common, the number of subchapters.
UL and SoL both tie at a total of 49 subchapters, while ZL being a 'new' story to our cats, has WAY less subchapters than both UL and SoL, only having 10.
So a mild prediction is that ZL will follow the same route as UL and SoL, 49 subchapters, last one having a single stage, with enemies like Hannya, Old Queen V, Zyclone and many others being introduced into ZL.
2. Similarities between both UL and ZL.
A coincidence is that UL and ZL share a similarity, having a SINGLE STAGE in their first subchapters.
Example: UL introduced Relic Doge and Relic Bun Bun to the player, with it having a single stage [An Ancient Curse].
ZL had only a single stage for their first subchapter, with it being 'A Whole New World' featuring Filibuster Cat's true form and Magamojoe, similar to a awakening stage.
Maybe as one of the final subchapters, we may encounter a version of 'Humanity Catified', featuring EVERY Legend Unit [except Luza/Zero Luza or Socrates] as bosses.
3. A introduction to a new enemy trait.
UL had introduced a new trait in the game, Relics, with them having a ability known as curse.
ZL is slowly but surely revealing a new trait, Sage, with no abilities yet revealed.
Remember, these are all predictions so they are likely to be incorrect!
This is all for now, we'll have to wait and see what PONOS has planned for ZL.
