Ripping from PS3/XBOX360 can be done, but it's tricky, so X-MEN Destiny may or may not be possible.
There are a lot of Marvel Voice packs here from X-Men Legends 1 & 2 as Well as Marvel Ultimate Alliance.

As for Marvel Heroes. I was trying and having no luck. Especially because in an update, they changed the compression and formatting of their sound packs. This happens sometimes whenever they add new content. When it keeps changing like that, sometimes it's hard to come up with a method for ripping.
