It's likely better to revise the general trends in each typing instead of the special abilities relative to only a few pokemon, as it is much easier to compare across versus matchups.
For example, it's true Dragon type moves include that of space-time, but considering this is only applicable to very few moves it would likely be incorrect to categorize all such abilities as dragon type moves.
After all, Celebi, Hoopa and even Shaymin all have similar abilities yet the typing of their attacks are left unaltered.
Further, Giratina has Shadow Force, in which it either teleports, breaks/phase through dimensional barriers, or both, yet this is a ghost type move.
The weaker variant Phantom Force also involves teleportation yet is a dark type attack.
These special abilities are more reflective of the nature of the normal users, than the actual moves themselves. They're the exceptions, and should be treated as such.
I agree with Fasial in that Dragon type attacks should be omitted, as the typing usually involves energy manipulation of a special variety not easily equalized in verses. The same could be said for Fairy as they have no general trend of abilities (though I usually considered them to be light since they're the antithesis of dark types and similar abilities seem to support this I admit it's probably easier to forgo this entirely).
If we use my suggestion of the general trends, then typing considered to be difficult to scale such as steel types which usually, despite few exceptions, focuses on metal manipulation and normal types which usual deals with the physical, much confusion is greatly decreased.
Dark types are tricky. Many animations do depict them of using dark energy (dark void, dark pulse, bite in some pokemon side games) but it's also simply a category where abilities that may seem malicious or dishonorable are held (knockoff, punishment, torment) with no other particular features (in the anime and main games bite is simply pokemon literally biting each other).
As such, relating to moves with a sort of dark energy is likely preferable to that of the other "normal" moves mixed in.
Finally, I don't think individuals affected by such attacks should be regarded as being "super effective".
Pokemon are effected by such due to their unique physiology, something most characters from outside the verse lacks hence it would be faulty to hold them by the same standards unless it's a weakness noted on their profiles.
@DT I agree. In the anime and manga, at least, attack potency is considered to be a higher priority than typing. However, it should still be considered immunity as Pokemon in the same level of power usually aren't affected.
