On a side note, Oda is really making mythical zoan fruits impressive, which is good comparatively to regular zoan fruits which seemed to be lacking in versatility outside of increase physical stats
With his mythical zoan, Marco can
- Fly
- Increase physical stats with full zoan and hybrid form
- Regenerate from any damage until a certain limit
- Transfer healing to other people(although limited) to the point of helping in boosting capabilities to stop Queen's virus
- Generate blue flames superior to regular fire
No wonder it's rarer than even logia
Kaido on the other hand gains
- Flight
- Increase in durability
- Increase in physical stats with full zoan and hybrid
- Elemental range attacks(fire, thunder, wind)
And we know normal zoans' awakening grants you a great recovery speed too, let alone a mythical zoan then
Knowing this though, it's a bit shame that Kaido has no mythical zoan user in his crew when he has beast theme
