Quote function didn't work, so as spetznaz put it so well ...
[i]"- Magic: Constantine. I could never fully trust him, but he seemed like a good guy training Tim in the Books of Magic. Additionally, he is likely to be more patient than Doom would be, and even if I fail he’d give me some pen or string that if rubbed or spat on could save me from a situation once;
- Science: Pym, since is at least get something I could put to immediate use;
- Unarmed combat: Wildcat if I only have 3 months. I’d prefer DareDevil if I had a longer time period, especially since he’d use his senses to make sure I’m moving right, breathing right, maybe even thinking right. With more time DD could even help me learn more exotic moves. However, 3 months is the stipulated time limit, and that’s why I’d choose WC. He can teach me dirty boxing to a good level in 3 months. Not enough to be a championship boxer, but enough to be able to put a serious hurt on someone;
- Weapons training: Punisher, for similar reasons (3 months). Just like DD above, if I had more time I’d chose Deathstroke as he’d probably show me a lot more than Frank could. But with just 3 months, Frank could teach me basics, and then drill those basics until it’s as easy and simple as breathing to draw quick and shoot Mozambique, shoot on the move, proper use of cover and concealment, etc. Frank could make me perfect at basics in 3 months, while Slade would only teach me low level exotic stuff in the same time period;
- Physical fitness: Easily Nightwing, just to say I learned from the man who learned from the Bat. Additionally, while Cyclops has an amazing body, Nightwing’s is just as amazing PLUS it is fully functional as he relies on it as his primary weapon. I believe that Nightwing’s training would also be focused on not just strength and stamina, but also movement. Now, Cyclop’s also does the same ...and there’s a lot of movement in the danger room ...but it’s not at the same level as Nightwing."[i]
The only exception might be Doom: I may prefer him because he would know (I would think) how to better integrate magic with science and tech.
