Forum:Gladiator Beasts and Royal Oppression

If I were to have a Gladiator Beast on the field and my opponent had a face-up Royal oppression, when can he say that he activates RO? For ex:

I activate Gladiator Beast Laquari at the end of the battle phase and he had attacked. I would say 'I activate Gladiator Beast Laquari's effect' and wait for a response. If my opponent agreed to it and didn't decide to use his Royal Oppression, and I then tagged him out for another Gladiator Beast, would he be able to activate his Royal Oppression after I pulled it out? Or would the chain window have already passed?
