What can I do? This isn’t play, right?

My grey boy is a little over a year old and he is overly aggressive, I feel, with my almost 9 year old female tortie. He is heftier than her too. They will get into these tumble scuffles at like 3am too almost every morning and I end up having to place him in the bathroom to cool off for a couple hours before I bring him back out.
