All About Battle Events

In an effort to discover how battle events make a specific character turn into another, I commented on locke's scenario, where he steals a merchant's clothes in battle.

Code:

11 - Open text box
01 0F - Text box 0F "Stole his clothing"
0E - Begin action
03 01 - For character 01 (Locke)
6C A7 - Jumps to the middle of the screen
0F - Proceed with Queue
01 0E - Text box 0E "Locke: Here we go"
0E - Begin action
03 01 - For character 01 (Locke)
84 A7 - Locke spins, battle sprite is changed
0F - End Character Queue?
01 0C - More Text
10 = ?
0E = Begin Action
03 01 - For Locke
35 A8 - Jump back to fighting position
0F - End queue
FF - End event

Seems like:
04 A8 - Merchant
84 A7 - Soldier

And here's the code for another event, in which terra turns into her esper form via an event command:

Code:

0E - Begin action
03 00 - action for character 00
A6 A9 -
04 00 -
DB A9 - Screen turns black
0F - Execute queue
10- ?
FF - End
