As for Jigglypuff, it is a common reoccurring Pokemon in the anime and is popular and well known because of it. It's likely the reason why it appears in Super Smash Bros. But outside of this there isn't much to go off of.

Red and his Clefairy can actually be seen in the Advance Generation episode, Lights, Camerupt, Action! (episode 86). Implying some form of connection.

Now, Pokemon Yellow is based on the anime. There isn't really a Pokemon in the anime that can be considered a counterpart to Pikachu. Jigglypuff is a common pink reoccurring Pokemon in the anime, and Clefairy was seen as a mascot of sorts before Pikachu and was used before it.

So currently as it stands, there seems to be data for Japanese Blue (which would be Blue and Red here) and Pokemon Yellow. Said that contains information for Yellow to have been released with a Pokemon Pink. https://t.co/WjJLfcHZ6r

Official artwork of Mega Charizard X and Mega Charizard Y.

Charizard was given a new cry with the release of Pokemon X and Y. Like most Mega Evolutions, Mega Charizard X uses Charizard's as a base with a filter. However, Mega Charizard Y uses Charizard's pre-gen 6 cry as a base.

Korrina's Masters battle portrait is still representative of her standard main series artwork. However, it is slightly different in posture with her right hand being held up rather than being held back.

In Pokemon Masters, a Trainer's stock image on the stats screen, default model preview and/or battle portrait are often depicted with their official main series art as a base. Korrina's uses her Successor battle art instead of her main art. This likely because she is in the air.

Currently, Tynamo, Eeletrik, and Eelektross are the only Pokemon to not have any form of weakness, due it's levitate ability eliminating it's single Ground-Type weakness. However if suppressed, changed or ignored, this trait is removed.

It should be noted that Rookidee, and it's evolution, Corvisquire, are the first non-legendary Pokemon to be pure Flying-Type.

While many have many extremely minor touches on their models upon generational shift, Glameow's had it's ears tilted from Generation 6 to 7 in order to better match it's official artwork.
