[Meta thread] Iron's PokeRole Adventure: The Skull Ruins

[Dragonstrike]

Alola Forms are no Deltas, neither for Shiva nor for me, so that doesn't really count as a point.

Technically Delta or not, there's similarities.  Different type, changed appearances (though only fan 'Deltas' typically do it), learnsets adapted to their new typing...what makes them so different besides the original idea in the TCG not including altered appearances (though they would commonly radiate a strange aura instead in the artwork, even the naturally occurring ones) and the official names?
