Depowering a Witch: Become a Pharmacist instead!

Kusuriya no Hitorigoto X-Over: For Holly Potter, she studied herbs. So she can eat what can be eaten when she's kicked out by the Dursleys using some shitty excuse. Not only that, she also studied powers from Marvel Comics as she was aware she has powers yet no clue how to use them. However, an experiment went awry...and she's in a new body of a deceased mad scientist.
