Cool cannot wait to try this out, I have been looking at your Mega Evos folder and they all have a story of their own. What tips do you have for people designing fan-MegaEvos and Fakemon for the first time?
Well for Fakemon, inspiration comes from all around you. Nature, media, etc. Let that influence your designs. Look at real Pokemon for guides as to how your Fakemon should look like. What eyes do Pokemon have? Mouths? Claws? Wings? All these minor characteristics can greatly decide how a design turns out. Try to avoid overdetailing Pokemon, as that's an immediate red flag for most community members. Avoid making things too generic (take a lion cub and slap a fire on its mane, take a horse and slap leaves all over it, etc). It's cliche, boring, and overall makes your Fakemon lose its uniqueness. Granted, it depends on how you handle it, but really. Learn to think outside the box. Use more than just black/white as shading/highlights. Experiment!
Megas are a bit different, but still follow the same rules. Most of the time, it's a hit/miss with their designs depending on how you do it. Looking at official Megas, they either just get some hair/fluff/armor/color slapped onto their normal formes (e.g. Mega Ampharos is Ampharos but with a glorious mane and a few aesthetic changes). Some Megas, like Aggron and Mewtwo Y change their body shape dramatically (but not extreme enough to make them a new Pokemon). Overdetailing can still screw over Megas as it can with Fakemon. Not playing enough with their designs, however, can also screw them up too. It can be difficult getting the perfect balance for a Mega Pokemon without making it look ridiculous. Just have good references, don't derive too much from the original design, and most importantly, have the motivation to do it. It's a tough gamble, but it can be done so long as if you have a clear picture.
We can't have Mega Mismagius without Mega Honchkrow
Honchkrow @ Honchkrowite EVs: 6 HP/200ATK/255Spd
Dark/Flying Ability: Prankster/Inner Focus/Fairy Disable* Fairy Disable: Immune to Fairy moves cancelling it's weakness to fairy Hasty Nature Aerial Ace Dark Pulse/Shadow Ball Fly Foul Play/Sucker Punch
Adamant Honchkrow Dark Pulse Foul Play Torment Acrobatics
Though Honchkrow has a weakness to the new Fairy Type, it's ability "Fairy Disable" Protects it. Also during night time if it has Ghost/Dark moves it's attack doubles to make it even more of a threat and cause destruction.
(Mega Honchkrow came to mind when i saw this, i made it up cause I'm bored)
Aerial Ave and Fly are vastly inferior moves compared to Brave Bird, while Shadow Ball should never be used on a Dark-type that gets Dark Pulse. Foul Play is a move that should never be used either, as despite being listed at 95 Base Power, Foul Play only does damage based on the opposing Pokemon's Attack stat. That second set, I'll just explain the flaws rather than do my own set. Dark Pulse on Adamant Honchkrow, even though its nature lowers it Special Attack. Foul Play is here again, and again, it only does damage based on the opposing Pokemon's Attack stat. Torment doesn't seem like that good of a move. While not only can Honchkrow not get Acrobatics, but Acrobatics would be weak with a held item equipped.
Mismagius has always been a rather scary Pokemon to fight against, and its access to a Mega Evolution makes it even more so. Having the same Special Attack as Chandelure, while also possessing an awesome Base 125 Speed and Special Defense, as well as access to the amazing Magic Bounce ability, means that Mismagius can have a fairly easy time sweeping... except for one thing. Mega Mismagius has two easily exploitable quadruple weaknesses to Ghost and Dark, making her rather easy to take down. But, if you can use her to her strengths, you won't be disappointed. Miamagius has access to Nasty Plot, which, combined with STAB Shadow Ball and Psychic, means that very few Pokemon will be able to switch into its hits. Hidden Power Fighting covers the remaining Dark-types that resist her STAB combination, and has the added bonus of getting a OHKO on Greninja and a 2HKO on Tyranitar in a sandstorm, both after a Nasty Plot.
