The TMNT? Oh, that would be hilarious! They might be welcome on Menagerie as Faunus, but I'm not sure. With Salem involved, they might try to take her down. I could see them taking care of Grimm easily, and maybe do a good job snaking around her castle and the Monstra. As long as they conceal their emotions, things will be good. The only other thing I can imagine is Mikey creating a lot of pizza if he had the Staff of Creation.

No, I don't think it's overused. Some things are hard for the Doctor to do by hand, like disarming a bomb. So the sonic screwdriver is a very essential tool.
I didn't really like 11 Doctor's 1st TARDIS console. It looked really complex and disorganized. I thought the second one was much better. As for my favorite, I really like 13. I thought it looked very futuristic and alien, and those spikes in the middle made the room look 'alive'.
Oh, that's a tough question. Say what you will about RWBY, they know how to design weapons. My least favorite weapon would probably have to be Crocea Mors. I understand the first model being a 'hand-me-down', and it didn't seem very practical for modern day Grimm fighting. The upgrades made the weapon more effective, but I didn't really like the concept. Just make the sword and shield bigger? ...Okay.
My favorite weapon would probably have to be Magnhild. Grenades, giant hammer, what's not to like. I think what would make it better is if the weapon was in the Doom Slayer's grasp. Oh man, that would be awesome.
