Anakin Skywalker (AotC) vs Mighella

Fight takes place where Maul fought Mighella, Anakin has basically replaced Maul's position, and is in the same distance between Maul and Mighella. Both are at full strength, Anakin does not know Mighella has Force Lightning.

Anakin easily

Anakin gets shocked down.

Anakin wins. According to TCSWE, Mighella was “helpless” before Maul’s attack, and Anakin at this point is at least on Maul’s level.

Using quotes to take the actual events out of context is unbecoming. Yes, Mighella was helpless in the end. But she brought Maul to his knees with Lightning first.

Per Lucas in the AotC commentary Anakin cannot defend against lightning at this point. So he just gets shocked down.
