Does Zyra Breathe Oxygen or Carbon Dioxide?

Plants perform both aerobic and anaerobic respiration, so the answer is both, although I would suspect that her aerobic respiration has increased significantly since her taking on a human form.

Why not both? :D

In her lore she inhabits a human body. But plants also still need both. Soooooooo. Both?

Yes

Yes.

Whatever it is, for some reason it gives a plant giant half naked tits...

She breathes oxygen; in her shin she is red which means that she does not do photosynthesis. Plants that do not have photosynthesis respire, and therefore oxygen. Ps I know this is memes and games, but giving you the facts anyway.[slayer-jinx-catface]

No, she stole the post from reddit kappa.

Do vegetables breath oxygen or carbon dyoxide? brb i have to visit my local hospital to see.

Does Valoran have similar laws of physics/chemistry as we do? For all we know, they may not even have such thing as oxygen. It's all magic.

Either way, she drinks dihydrogen monoxide.

I thought she was a plant in human form...

Personally I'd say due to her past as more of a plant, she would be able to breathe CO2, rather than oxygen, just like a plant.

She is still in a human body however so she would probably need Oxygen. I'd wager that a lack of oxygen won’t kill her or knock her out, and she can still breathe the air like any other human, but she still requires CO2 to survive.
