After being away from MUGEN for a number of years, I started tinkering again after the release of MUGEN 1.0 (and a son who's old enough to enjoy it now). I always thought it would be nice for Wolverine and Sabretooth, and other appropriate characters to have an automatic (but somewhat slow) healing factor. I've done that, with some help from Zvitor's Wolverine, and patched up Wolverine [Wx2] by Ariel AleX Co. and Sabretooth by Jin Kazama. You can see a video of how it works here:
