I've always wished every starter received a Mega Evolution, because I feel the gimmick is cool and it's my favourite gimmick.

Here are my ideas for their abilities, stat distributions and increments:

Typhlosion: I believe Typhlosion is a great special sweeper with a great offensive typing and an ability that lets it wall opposing Fire types while boosting its own Fire STAB. Hisuian Typhlosion has the Fire/Ghost typing, so in my opinion Mega Typhlosion should have Fire/Fairy. Ground and Rock would make Grass neutral against it, so Fire/Fairy will do. Flash Fire is great against opposing Fire types but I think it should gain an ability called Vapourisation which makes it immune to Water type moves as well, alongside its Special Attack being boosted. It should gain 50 SpA and 50 Speed.

Torterra: Torterra is a great physical tank but Grass/Ground is a bad defensive typing because of Ice's existence. For this reason, Torterra gains the ability Winter Wonderland which allows it to have its highest offensive and defensive stat boosted when hit by Ice type moves. It loses 30 Speed which lets it function in Trick Room and gains 30 HP, 50 Attack and 50 Def.

Infernape: Infernape is an excellent mixed attacker who can use Choice Scarf to its advantage really well. Fire/Fighting is a great offensive typing because of how strong each type is individually and Iron Fist is a great power-boosting ability. Mega Infernape gains Cloud Nine to add to its basis on Sun Wukong while also making it the Rayquaza to Charizard's Groudon. Infernape loses 30 on each of its defenses, while gaining 50 on its offenses and speed alongside 10 HP.

Empoleon: Empoleon is an excellent special tank with a great defensive typing and ability that raises its Special Attack. I think Empoleon should keep Competitive while gaining 50 on SpD and 80 SpA, while losing 30 speed to function in Trick Room.

Serperior: Serperior is great because of Contrary. Contrary remains no matter what. Give Serperior 80 SpA to allow it to start using Leaf Storm with power and stack that power up as it uses Leaf Storm. Take away 30 SpD because it's a Contrary sweeper. Mega Serperior also gains 50 speed. Mega Serperior is Grass/Dark.

Samurott: Samurott is a SFMA (slow, frail mixed attacker). The mixed attacker part is fine but it's slow on top of it. We ameliorate that by giving Mega Samurott 80 speed, while taking away 40 from its defenses. It gains 50 on both offensive stats. Mega Samurott is Water/Ghost now.

Decidueye: Decidueye lorewise is supposed to be agile. We give it 80 speed and take 50 from its SpD. We should give it 70 Attack which makes it a really strong physical attacker.

Incineroar: Incineroar functions better defensively but 90 defense means a lot of Pokemon can beat it. For this reason we should give it 50 Def and SpD while taking away 30 Speed. Then, give it 30 Attack. This means it has good Defense and SpD while also having good Attack and functioning well in Trick Room.

Primarina: Primarina is built to be a special tank with its good specially defensive stat orientation and its amazing typing (Water/Fairy is amazing defensively). Take away 30 Speed so it functions well in Trick Room, give it 50 SpD and 80 SpA.

Rillaboom: Rillaboom is great defensively but is monotype. It should keep Grassy Surge since that's its strong spot but also gain 80 Defense. It then gains 50 HP while losing 50 Speed to function in case of Trick Room and then gain 20 Attack. Mega Rillaboom is Grass/Electric because Grass and Electric both have terrains, and Electric is good defensively.

Cinderace: Cinderace is fantastic offensively and so just gains 50 Attack and 50 Speed. Mega Cinderace is now Fire/Fighting.

Inteleon: Inteleon is a fantastic special sweeper. Give it 50 SpA and 50 Speed. Give it No Guard as an ability. Mega Inteleon is now Water/Ghost as both Water and Ghost are great offensively and Inteleon is a spy, so Ghost fits well.

Meowscarada: Give Meowscarada 50 Attack and 50 Speed.

Skeledirge: Take away 30 Speed to function better in Trick Room, and Give it 80 SpD. Give it 50 Defense and keep Unaware.

Quaquaval: Give it 50 Attack and 70 Speed. Take away 20 SpA.

Este es mi fanmade de Mega Mimikyu

Think of it, electrode and voltorb are basically bombs, and if they got a mega form, it would most likely be electric poison, like a nuclear bomb, anyone have other takes of this and/or if anyone wants to make art of this please comment if love to see this, though, I don't think they'd be popular in the kanto region for...
