Can u give us some hcs about pokemon with extreme or difficult or just straight up weird mega evos
Mega evolving a Kangaskhan seems to cause the baby to develop faster than usual. This does not appear to otherwise harm them, though the effects are still being studied.
On the rare occasions where a Kangaskhan is mega evolved without a child present, the parent will mega evolve instead. Both forms are allowed in official competitions.
Lucario just go completely feral when mega evolved, so having a strong trainer bond is especially important with them.
There is an ongoing debate in the scientific community about whether or not Aerodactyl's mega is its original form or a result of the fossil restoration process.
Mewtwo's mega evolutions are only speculated upon in-universe, because no one is partnered with the single Mewtwo in existance.
Mega Tyranitar's back splits open during mega evolution, very similar to how it evolves from Larvitar.
Both of Mega Mawile's new mouths can be used to eat.
Mega Venusaur has roots growing straight into its nerves.
Slowbro's Shellder is thought to gain extra intelligence through mega evolution. Studies have shown that Slowbro's body partially fuses with the Shellder as well, not that it notices or cares.
Mega Sableye will sometimes eat their own shield gem, if they happen to be peckish after evolving.
Mega Banette are still capable of zipping up, and will sometimes do so to avoid accidentally cursing their own trainer.
The hardest mega evolutions to achieve are Scizor, Houndoom, Tyranitar, Banette, Lucario, Glalie, Salamence, and Metagross (due to a combo of the Pokemon becoming more violent, and the evolution in question being either painful and/or dangerous if sustained for too long; a strong bond and careful practice is required to achieve these).
The easiest are considered to be Kangaskhan, Gardevoir, Medicham, Absol, Slowbro, Altaria, and Audino; all handle the process extremely well, and are good "beginner Pokemon" for those wanting to practice mega evolution.
