Role Identification: Just slap a Sitrus berry or a Mago Berry and watch Mind Blown and Light of Ruin take lives! Alternatively you could just make a Choice Specs set with Fire Blast and Moonblast, but that's not as fun...

Raikeon
DNA Donors: Raikou & Jolteon
Ability: Duke of the Lightning
(Pressure & Quick Feet) - User's Speed is doubled.
Stats: 93 HP
(+16) / 85 Atk
(+10) / 75 Def
(+8) / 112 SpA
(±0) / 100 SpD
(+3) / 125 Spe
(+3) - 590 BST
Notable Moves: Thunder Wave, Thunderbolt, Volt Switch, Calm Mind, Aura Sphere, Hidden Power
Role Identification: A reliable revenge killer thanks to its astronomical Speed stat, it is pretty similar to Hawlucha in OU but without the Terrain Support and the one dimensionality, however, it is still rather weak, even when running Modest, and the lack of coverage really hurts it.
Enteon
DNA Donors: Entei & Flareon
Ability: Emperor of the Fire
(Pressure & Guts) - User's Attack is doubled.
Stats: 93 HP
(+3) / 125 Atk
(+3) / 75 Def
(+3) / 100 SpA
(+8) / 112 SpD
(+20) / 85 Spe
(+3) - 590 BST
Notable Moves: Sacred Fire, Flare Blitz, Extreme Speed, Stone Edge, Superpower, Bulldoze
Role Identification: A deadly wallbreaker with an astronomical Attack stat capable of denting the entire tier hard, Extreme Speed makes up for its subpar Speed stat and allows it to sweep games on its own, however, mediocre bulk and lack of coverage means most Fire immune Pokémon can deal with it.
Suiceon
DNA Donors: Suicune & Vaporeon
Ability: Monarch of the Rain
(Pressure & Water Absorb) - Doubles HP healing effect (Wish Recovers 100%, Aqua Ring restores 1/8).
Stats: 125 HP
(+10) / 75 Atk
(+5) / 94 Def
(+7) / 100 SpA
(±0) / 112 SpD
(+7) / 86 Spe
(+11) - 592 BST
Notable Moves: Wish, Scald, Calm Mind, Roar, Stored Power, Protect
Role Identification: With outstanding bulk and an outstanding ability, this thing is tough to break down, recovering 100% HP with Wish is no joke and allows it to deal with many of the powerful Wallbreakers in the tier, also Roar allows it to threaten set up sweepers while Calm Mind and Stored Power turn it into a powerful late game cleaner, however, it is complete Taunt bait and powerful Electric- and Grass-types may overcome its bulk without much issue.
