Do damage counters already on Captain Elita-1 affect how many I can move onto her?
Yes. For example, if Captain Elita-1 (with 17 health) already has 9 damage counters on her, you can’t move more than 7 more damage counters onto her using her ability.
Does moving damage counters from one character to another count as repairing the first character or doing damage to the second character?
No. Any abilities that care about damage being done or repaired won’t affect the move.
The card will stay in the scrap pile.
If Captain Elita-1 is my last character and is KO’d, do I get to use her ability before I lose the game?
No. You’ll lose the game just after she is KO’d, before you can use her ability.
How does the new Captain Elita-1 interact with I Still Function!
? If my opponent KO’s her during their turn, and I scrap I Still Function as one of the two cards from her trigger, is Elita-1 a valid target for the card?
Elita-1 would be a valid target for I Still Function!
, but she would still be KO’d at the end of the turn. She would trigger again.
What if I use I Still Function during my turn to bring back Elita-1 and then, at end of turn, when she is KO’d again, she reveals another I Still Function? If I am able to bring back a character with it, when is that character KO’d by I Still Function's effect?
Almost immediately. At the end of that turn.
