1. Alright, so they'll be prevalent in the tournament.
2. So that can be done, then, in theory. Neat.
3. I mean... Frieza's family line did all have at least four forms (assuming Cold was similar to his sons), but the extra forms were apparently additional [i]downgrades[/i] to their true forms, such that (using Final Hours' terminology) they'd end up having the Diplomatic form, two Combat forms, and their True form, with only Cooler having the skill to remain in his True form at all times, and only Cooler having the ability to transform [i]up[/i] from their True form until Frieza basically BSed his way into acquiring his Ultimate Evolution, though even then, the latter remained in his Diplomatic form until he actually needed to transform up. Basically, there's a certain precedent for an Arcosian being able to transform up from their True form if they succeed in controlling their True form's power, and considering that all it would realistically represent is a power increase (albeit a potentially large one depending on the owner), I don't necessarily see why it wouldn't be viable to include a Super transformation as part of a particular Arcosian character's arsenal.
4. Oh, okay, transformation alters DNA for more diversity, and only Pure Arcosians are counted as Arcosians. I guess that makes sense, and explains the unasked question of how form changes alter reproduction, though "75" possible parents per Pure blooded Clan is still way less than what's needed to eliminate inbreeding. Hell, even "300" possible parents doesn't eliminate that risk, even if every one of those parents is non-choosy about producing multi-ethnicity children.
5. Fair enough about the cultures.
