Ok

Flight

You would get hydrogen in your body so quickly you skin would litteraly bubble and boil and burn up in the atmostsphere

Being able to breathe and see underwater and not be affected by water pressure

The only thing i can imagine would be be you staying under water too long and losing muscle mass in legs and having trouble walking

But you'd constantly use your legs to swim

I guess but you might be floating around a lot

Being able to kill anyone with a single thought as of I wish you were dead

You might accidently think of yourself or maybe everyone on earth

I’d for sure do that

I

obligatory your mother joke here

being able to charge, trimp and be a demolition expert like demoman tf2

No bad effects, you picked the best superpower ever

Lesgoo

Creation

We arent sure what happens when matter is purely created from nowhere, because the law of matyer conversion states that no matter is created or lost, just transferred
Could end all of reality

Shape shifting

No reprucussions, congrats🏅

Ackshually it's possible your organs and blood could be badly damaged

🤓

Phytokinesis

Please explain

control plants

Hmmmmmmmm probably just if you move big trees the ground would get unstable

Cytokineses? (control ice)

No reprucussions congrats🏅

Cryo* and one could be accidently freezing your blood

K

Teleportation
(You would continously be cloned, or you would die and a copy of you would end up where you wanted to teleport)

Hmmm you could either teleport into wall floor ceiling car train or even person

Invisibility

Freezing time would cause light and heat to freeze as well, so it would become suddenly dark and cold

Freezing time would make you blind and deaf since light and sound wont move and you too would be frozen since it takes time to move your muscles
