I played MKD and MKA, and I watched the rest on youtube. Can I get some answers I've been trying to figure out?

1. MKD: How do I get the unlockable characters? Not the chest ones, I already got those, but the ones I saw on youtube. Like Drahmin, or Kitana?

2. MKA: How come in a video I saw, Taven had a sword in konquest, throughtout the entire thind, and I only get the ones laying around that poof away and I can't keep them?

3. MKA: When Li Mei said "Die Shinnok!", how can he die if he is in the place where dead people go to?

4. MKSM: Why does Shang Tsung look old, but in MKD, he looks younger?

5. MKD: Who is the guy who pops up in the little cave in the Nethrrealm and says "Here, take this." and he gives you money?

6. MKD: What does Ermac look like without the black material covering his face?

7. MKA: Who was the vulture eating in the oppening movie?

8. MKA: Who is the floating purple guy in the evil tower? I also saw him in the portal arena in MKD.

9. MK2: What are those curved lines Kitana releases from her fans? Are they sound waves?

10. MK vs DC: shouldn't Earthrealm be the same thing as the planet the DC guys are from? I saw that Mokap is from Chicago, and that's in America, and so is the place where the DCs are from.

11. How the HELL does Lui Kang do that arcade drop fatality? Is it a magic trick, or is it just plain cartoon physics? Same with Mileena sucking in the enemy in MK2, Johnny Cage ripping a body in half WHILE it's still standing, Johnny punching Kung Lao's head three times in MK2, and Baraka's blades fitting in his arms when they are obviously longer.

So yeha, I just didn't want to make each question in a different thread, so I put all of them in here. I have a lot more, but I don't plan on wasting all of your times. Thanx!
