"As a countable noun ("a continuity"), "continuity" is often used to refer to a set of stories that are mutually
Canon, a sort of self-contained possible world. (Compare and contrast with
The Verse, where not everything has to be canon.) For example, a series would typically have its own continuity, and sometimes two series by the same author are in the same continuity, so that what has happened in one is canon in the other; but if they aren't, it's not. In other words, a continuity is that inside which there needs to be continuity, and outside of which there doesn't. It follows from this that in some cases it's not possible to tell whether the word is being used like a count noun or not, but then it makes no difference for meaning anyway"
This is something I found on TV Tropes and was what I was referring to when mentioning continuity. Is "mutually canon" overselling the correlation of the media forms of Kirby and Pokémon? Yes, very much so. As a matter of fact there may be another term that better covers the topic at hand.
"Expanded Universe refers to everything that is not the primary medium. All that other stuff.
This can create a schism in fans. Some believe the entire Expanded Universe is
canon. Others reject it all. Others pick and choose based on closeness to the writers of the primary medium. Expanded Universe material is usually written so that it can be fit in to the
canon without having to alter the
canon itself. However, later developments in the actual series can make it definitively out of
continuity"
That sounds a lot more like our predicament now doesn't it?
So let's say the Pokémon and Kirby games are the primary mediums and the anime is the expanded universe. I feel that for the best discussion that we should choose based on the closeness to the primary medium. So let's do some analysis
So the Pokémon and Kirby expanded universes both use slightly modified versions of characters from the primary medium, slightly modified settings, a moderately modified plot, etc. The trend here is the expanded universe is as it sounds, it
expands on the current universe but doesn't really add to the primary universe. Now here is where the differences start to pop up. The Pokémon media is all advertised as very closely correlated the video games, TCG, anime, they're all one big package to the naked eye but when examined, how many elements are actually taken from the expanded universe and put into the games? Spoiler alert: not many.
Off the top of my head I can think of the promotional Pokémon, special Pikachu, and maybe a cameo of a character or a small nod to the anime (Red's Pikachu in HGSS). Now that's 2 things and some cameos for the Pokémon side, now over to Kirby. Kirby's "poyo" language from the anime has been featured in several games, it marked the debut of the Spear Waddle Dees as well as the water ability. There are also a few smaller nods like the anime designs of D3's castle and the Halberd as well as the changing design of Galaxia (which was named in the anime). Now that's three specific things and a couple of small nods and cameos along the way. I feel that's enough for now. When you acknowledged the Sonic correlations that was one element for each part of the expanded universe, nothing more nothing less. I feel that the anime of both Pokémon and Kirby are close enough to be considered while the Sonic expanded universe is a little too scattered to be considered
Am I straw grasping? Maybe.
Is my incredible Kirby bias showing through? Probably.
Am I going through all of this to keep the discussion hot? Most definitely.
