Flareon-Mega
Ability: Flash Fire /
Guts -
Wild Fire (Gale Wings/Technician clone [moves 60BP and under have +1 priority]) (Breloom has an identical ability that does the same thing but better)
Wild Fire (Dashing Fists clone, see mega breloom or the new abilities tab in the spreadsheet

HP: 95 ----> 95
Attack: 130 ----> 155 (+25)

Special Attack: 95 ----> 130 (+35)
Special Defense: 110 ----> 100 (-10)
Speed: 65 ----> 105 (+40)
Base Stat Total: 525 ----> 625 (+100)
Movepool Additions: Flame Wheel, Nuzzle
Competitive Role: While flareon still lacks heavily coverage wise, an ability that gives it a unique quality in getting STAB fire priority (not stolen from mace master lol), and great physical and special attacking stats make this thing usable in tiers higher than PU. It has the ability to boost its speed with a +1 priority attack in flame charge or 100% paralyze any mon with nuzzle (that isnt a ground type or under special circumstances, this is not broken as thundurus gets prankster t-wave and that is not broken, this works the same way). This makes a mon with lacking speed (for a mega) very viable after setting up due to its ability to boost it's speed, paralyze, and use moves like bite and flame wheel with priority (quick attack gets +2 prio).

Quick Feet - Galvanize

Stats:
HP: 65 ----> 65
Attack: 65 ----> 95 (+30)

Special Attack: 110 ----> 140 (+30)
Special Defense: 95 ----> 100 (+5)
Speed: 130 ----> 165 (+35)
Base Stat Total: 525 ----> 625 (+100)
Movepool Additions: Extreme Speed,
Spikes Electro Ball
Competitive Role: Jolteon's mega makes it into a strong special sweeper, thats it. It gets STAB hyper voice (which does less than thunder, but is better than t-bolt), and STAB extreme speed.
You can use spikes if you predict a switch, but it's mostly there for flavor. I opted for electro ball instead, this allows for a strong STAB attack that puts incredibly fast move to good use.
Vaporeon-Mega
Ability: Water Absorb /
Hydration - Rain Dish

Stats:
HP: 130 ---->130
Attack: 65 ----> 35 (-30)

Special Defense: 95 ----> 155 (+60)
Speed: 65 ----> 65 (+0)
Base Stat Total: 525 ----> 625 (+100)
Movepool Additions: Energy Ball, Soak
Competitive Role: Im getting lazy with the descriptions so i'm going to keep this brief. With a solid rain setter, you can have a stall monster. Imaging having 1/16 recovery for 7 turns while this thing pumps out rain boosted scalds and toxics. Without the rain though, It is still very usable. A calm mind/ three attack set could be very scary with it's incredible base 130/100/155 bulk.
Sylveon-Mega
Ability: Cute Charm /
Pixilate - Fairy Aura

Stats:
HP: 95 ----> 95

Speed: 60 ----> 120 (+60)
Base Stat Total: 525 ----> 625 (+100)
Movepool Additions: Aura Sphere
Competitive Role: Sylveon loses STAB hyper voice, but it doesn't miss it, instead, it welcomes it's disgusting new gift of STAB fairy aura moonblast. Period. thats it. bring special sylveon, mega, and click moonblast till you die. Aura sphere is good for coverage. Physical sweepers will eat this thing for breakfast though, watch out.
