the mad scientist ruins patrick stars experiments at the lab every day.
your answer
the mad scientist ruins patrick stars experiments at the lab every day.

Explanation:

The original sentence is already in the active voice, which emphasizes the doer (the mad scientist). Since the task is to emphasize who/what did the action without changing meaning or tense, and the sentence is in active voice (where the subject does the action), we just keep the order as it is.

Answer:

The mad scientist ruins Patrick Star's experiments at the lab every day.
