"This will be the main role of this short film where, apart from the short dialogues, there is a part where the character screams in rage. (and I would like that to be noticeable in the scream)

Samus is transforming, trying to control it, but the rage controls her. She transforms into Metroid mode and goes in search of revenge.

here are some examples of what screams 

Metroid Dread: Samus Scream

Ryuko Matoi Screaming Sound Effect

This, especially from minute 0:00 to 0:16, is what I am looking for.

Goku vs Broly Super Saiyan Blue Transformation Scream Fan dub

I would like you to send a voice sample acting as the character. A normal casual voice like on a regular day (this is because if your performance convinces me, it will be the voice of the bounty hunter for the upcoming videos) and in this role, a voice that sounds angry and vengeful.
