Since half of them got their megadex entries, let's see some what-if entries for the others. I'll start.
>It's mega evolution was rumored to first appear when it was given a special stone by its owner during a special occasion.
>Ever since its mega evolution, it has developed a possessive attitude. It will not hesitate to attack anyone that comes near its trainer. Even if they are close relatives.
You can sum them all up as
>they're edgy and VIOLENT
ALL OF THEM because Rotom-Dex is a fucking Mega racist
I wouldn't be surprised if mega lop became a legit cocksucker.

Statistics don't lie, anon. Even though mega forms account for only 14% of the population, they are responsible for 85% of violent incidents

Ash-Greninja has powered up thanks to the strength of its bonds with Ash. This is the form Greninja takes when it has gained new power due to the miraculous occurrence known as the bond phenomenon. This can be brought on by the bonds between people and Pokémon. It seems that it has only been known to have occurred once—several hundred years ago.
Ash-Greninja's leg strength has been enhanced compared to an ordinary Greninja, making it difficult to see because of the speed at which it can move. It takes its enemies out in a flash! It becomes able to make giant Water Shurikens on its back, and it can throw them in rapid succession.

Those numbers are made up by anti-mega supremacist scientists and you fucking know it. It's all fucking propaganda.
Manectric

Mega Audio
>Thanks to mega evolution, it can hear more sounds than before, even others' thoughts. Despite hearing horrible things from another's mind, it will be healed if needed.
>It dedicates itself to heal allies and enemies alike, but end up neglecting its own care. An Audino can push itself to exaustion or death for the sake of its partners.

>This Slowbro has made a terrible mistake
>The Mega Evolution energy went into its horn, doubling its strength. It enjoys this newfound power, making it rather arrogant.
>The process of Mega Evolution fills it with power it has never known before. They become addicted after even one time as a result, and will go to any length to do it again.
