According to the question and the answer here, it is quite unresolved if Animagi can or cannot perform magic. However, is it possible to perform magical spells on Animagi (spells such as Stupify, Rictesumpra or any other common spells)? Except the spell to reverse transform animagi back to their human form, are there evidences of other spells cast on animagi?

    Spells that only affect humans and not animals might not work, but there's no reason to think other spells wouldn't. – Harry Johnston Apr 2 '18 at 11:06
  • @HarryJohnston That sounds about right. But are you aware of any instances where such a thing has been mentioned by JKR or any authentic source anywhere? – Shreedhar Apr 2 '18 at 15:49


Remus Lupin and Sirius Black threatened to perform magic on Wormtail should he transform. By definition, their threat would only have been carried out if Wormtail was in his rat form.

"I'm going to tie him up," said Lupin. "That's all, I swear."
Harry stepped out of the way. Thin cords shot from Lupin's wand this time, and next moment, Pettigrew was wriggling on the floor, bound and gagged.
"But if you transform, Peter, growled Black, his own wand pointing at Pettigrew, too, "we will kill you. You agree, Harry?"
Harry looked down at the pitiful figure on the floor, and nodded so that Pettigrew could see him.
(Prisoner of Azkaban, Chapter 19, The Servant of Lord Voldemort).

"One wrong move, Peter," said Lupin threateningly, ahead. His wand was still pointed sideways at Pettigrew's chest.
(Prisoner of Azkaban, Chapter 20, The Dementor's Kiss).

It's unclear exactly what spell they were proposing to use on Wormtail but it's a fair guess that it was Avada Kedavra. Since both Lupin and Black were deadly serious in their intent to revenge the Potters it's very unlikely that they would make this sort of threat if they were not capable of executing it.

We don't know whether other forms of magic work when cast upon Animagi. As far as I'm aware, this is the only instance of magic being performed on, or threatened towards, an Animagi. (Hermione performing an Unbreakable Charm on the jar containing Rita Skeeter is the next-closest example, but it scarcely counts). I don't see any reason why spells shouldn't work as they would upon normal animals since the Animagi becomes the animal in almost every respect.

  • Another example is the battle in the Ministry, if taking your Animagus form makes you invulnerable why wouldn't Sirius have done so? (This one is better, though.) – Harry Johnston Apr 3 '18 at 0:08
  • @HarryJohnston I don't think we was trying to make himself invulnerable at any point, though. I think he was trying to protect Harry from the Death Eaters. – The Dark Lord Apr 3 '18 at 7:04
  • ... and what better way to do that than to make himself invulnerable and then start biting their wand hands? :-) – Harry Johnston Apr 3 '18 at 8:28
