It's like you got some persoal vendetta on Pikmin for some reason.
Sheesh
It's like you have a personal mission to buff pikmin for some reason
Sheesh
A being that's a cross of a plant (known to release deadly toxins/pollen) and an animal (known to breathe out chemicals and other airbourne particles) has the plausibility of releasing a deadly cloud of poison.
A being that's a cross of a plant and an animal will have so many cellular screw ups it's not even funny, plausible doubt it,
longevity if plausible
not a chance.
Don't bring up, "no mouth" cuz they distinctly have their own version when they drink up nectar.
I'll bring up the fact that that is the only use they've had for the mouth, that could be pure absorption for all you know.
Absorption possible and doesn't need a mouth, which aesthetically is missing.
Just like a false pallet on Charizard and Bowser <_<
All of your other points are pretty fail.
All of your points on Olimar in general are pretty fail
Pika floating in the air via balloons? More of a hazard.
More like Death From Above
People jumping really high when it's realistically impossible?
The crossing of plants and animals when it's genetically impossible?
I've already explained many times over as to why it wasn't implemented into gameplay.
I've explained many times why one cutscene isn't justification.
Just can't accept a canon cutscene, can you?
Just can't accept what gameplay, says can you?
This is plausible, unlike all of your examples (excluding Pika stuff)
The whole basis of pikmin in of themselves is implausible due to the fact that they're cellularly screwed up. Being part plant and part animal in itself is a biological fallacy, animal cells can't supply what plants need, and plant cells can't supply what animals need. And both types of cells are incompatible to coexist seeing as how the immune system would kill one type of cell off as an invader and therefore killing the pikmin. Also to carry on dual life processes is something the pikmin couldn't do, not with the minimal energy they take in, photosynthesis with only that small flower can only provide so much, and for the pikmin to perform dual life processes and strain themselves physically, they'll drop like flies from over exhaustion.
Red Blood Cells- won't receive enough oxygen due to limited method of respiration
White Blood Cells- attack any intruding cells, in other words, cells that aren't animal cells, the plant cells are dead, leading to the death of the pikmin.
Plant Cells- can't diffuse some materials that the animal cell can, halving the productiveness of the body to perform functions that pikmin need to perform, being animals.
Immune System- works against itself recognizing the other half of cells as intruders and attacking it. You couldn't get away with saying "adaptation" to this because of how vastly different plant and animal cells are. An immune system will kill the plant cells, no immune system will have airborne bacteriophages kill the pikmin. Mixed immune system (if plants even have one, don't think they do) will attack itself, recognizing the other, completely different part as an intruder.
Having to have
Arteries
Veins
Capillaries
Xylem
Pholem.
The heart could only pump red blood cells, which are animal cells. Having to coincide a pressure system which moves plant cells through xylem and pholem would put too much pressure on a heart that had to be their size, too much strain leads to caridac rest, leads to death.
Not even evolution can explain such. And this is only the circulatory and immune systems.
And even if they have mouths, where will the nectar go, down an esophagus, into a stomach also ridden by the pressures of xylem and pholem and other tubes and stuff going throughout that small body?
Into the bloodstream? How? How's it going to be broken down?
The needs of the plant and animal to be met require too much energy and with such a limited way to get the energy the pikmin are gimped.
