Yes! The cartwheels are a plenty.

I am sure Harley here has lots of bad memories that would bother other people. Let's get the good ol' Joker out for Halloween.

While Harley rolls with the punches, and takes things with her own ray of sunshine... personally I would love her to show off her awesome fighting skills.

I do have other characters that I am willing to have paired up:
Hunter: losthunter -- while he doesn't have any particular bad memories for others to be pulled into, he does make for a good hapless victim.
April Kent: slayers_desire -- who doesn't want to get pulled into the Buffyverse, where vampires and demons become your worse nightmares.
Hermione Jean Granger: mudblood_andproud -- this young witch has experienced some pretty heavy torture. and had to survive very bad conditions.
