Similar supernatural aspects of verses get equalized in a reasonable fashion. So a supernatural energy that almost everyone in a Verse has, which is necessary to fight the characters of said Verse, will be assumed to be the equivalent energy that the opponents use in their techniques so that a proper fight can happen.
Furthermore, attacks that require a special type of energy to be effective, like anti-magic requiring magic, will be assumed to work against the energies of different Verses, as long as they are somehow similar and the mechanics are somehow compatible with the known mechanics behind the energies from different Verses. For example, mind control resistance by being a capable mind user would also work against other Verses, but mind control resistance through a strong will would not necessarily work against mind control from other Verses. It is also important to note that characters won't lose or gain any abilities or resistances which they do or do not inherently possess. However, if an ability has a weakness, condition, caveat, or limitation, consistently shown throughout its use (such as not working on characters under a specific condition, like energy gap) or stated by a valid and uncontradicted
statement, then it should be applicable after the equalization.
Equalization works highly on a case-by-case basis, so many relevant cases should be discussed in the versus thread itself.
