if you notice, zoan devil fruits have basic forms
1) pre-df species
2) df-granted species
3) hybrid, that mixes some good and bad aspects from each
trivia: btw i was the one who wrote the zoan df article ages ago, and it took me many tries to finally settle on 'pre-df specis' and 'df-granted'. just wanted you guys to know who wrote that and how hard it is to coin phrases such as these. not sure if it's been changed, but so there. i also wrote a huge majority of luffy's gear powers 4-5 years back, including the part 'equipping him with a mace of astounding mass'
anyway, let's take point forms out of the equation. i think they're just interpolations of transition between the first two states.
let's say we have a tomato, who eats a durian fruit.
1) tomato
2) durian
3) durato? tomian?
point forms would thus be:
maybe domato? durito (lol)? dumato?
hybrid would be either durato or tomian
now awakened forms seem to be not a mixture of both, but a COMBINATION of both.
instead of durato or tomian, we get duriantomato or tomatodurian, or dutorimaanto.
existing in this state requires them to be BOTH a full pre-df specie and a full df-granted specie at the same time. this would drain a lot on their stamina, as you're using up twice the stamina it takes to operate as any single specie. but if well regulated, the user also has access to twice the amount of basic faculties, such as healing, instead of just the BETTER of both, without the detriment of stamina drain.
This is like the strength factor, imagine if a human has a strength of 10 douriki, and a tiger has the strength of 15 douriki, going into hybrid merely selects the best of both, which is 15, whilst going into awakened mode combines both, into a total of 25. if their bodies are not used to it, however, they only have the stamina/nutrients to feed one single specie's actions, then they get drained very quickly. it also explains why chopper and the demon guards lose their mental faculties, because htye're running low on nutrients in the high-nutrient-drain form. this is similar to how people who are not used to exercise go sprinting for a few kilometres/miles and feel giddy after with a near non-operational brain
IMHO, that would be awakened zoan devil fruits. This is my hypothesis thus far.
edit: edited the durian/tomato text so it makes it easier to see
