Rescue kitten is food aggressive

Many of you are up-to-date on the background, well what is known about it, on Tyrion the kitten I rescued and I am trying to raise with the help of my 5 cats to get ready for a forever home (God willing!)  Well, he's food aggressive.  He goes from dish to dish growling and hissing and going crazy over the food.  He wants it all for himself!!!  Probably because I feed actual meat!  He's never had it so good in his young life!   Well, my cats don't know what to make of this?  They are very put off by it.  Mostly they are just like "What the H?  Here, dude, take it!  Dang man!"  So, while they are eating, I have to shut the little one in the bathroom to eat his and keep him there until the others are done.  Anyone know any tidbits on how to calm his food aggression?  It could hinder the adoption process when the time comes.

All my kittens growl over meat, especially once they are onto wings and necks.

And usually their first meals with the big cats at around 8 weeks they'll grumble and the big ones just stand back and wait.

Thank you!  I was just thrown by this behavior.  I'd never witnessed it before!  When King Arthur and Morgan La Fay were his age, they never acted like a little psycho like Tyrion does at meal time!
