Excellent, I've been waiting for this

Parents: Celebi / Drifblim
Shared egg group: DNA
Offspring name: Celeblim
New type: Grass/Ghost
New base stats: 125/100(90+10)/77(72+5)/100(95+5)/87(77+10)/100(90+10)(589)
New ability and desc: Unnatural Decay(Natural Cure + Aftermath) = Whenever Celeblim is switched out (including fainting), the opposing pokemon loses 1/8th of their HP
Notable Moves: Baton Pass, Calm Mind, Defog, Earth Power, Energy Ball, Explosion, Giga Drain, Heal Bell, Healing Wish, Hex, Knock Off, Leech Seed, Light Screen, Memento, Nasty Plot, Psychic, Recover, Reflect, Seed Bomb, Shadow Ball, Stealth Rock, Sucker Punch, Swords Dance, Tailwind, Thunderbolt, Thunder Wave, Toxic, Trick, U-Turn, Will-o-Wisp
Role identification: Celeblim can excel as a Baton Passer with access to 4 different boosting moves, especially with it's ability. However, it can perform a variety of roles with it's good bulk, decent attack and speed, and access to many support moves such as Will-o-Wisp, Leech Seed, Defog, Stealth Rock, Tailwind. It can perform as a wall, support, bulky offense, or even a set-up sweeper.

Parents: Camerupt / Sylveon
Shared egg group: Field
Offspring name: Sylverupt
New type: Ground/Fairy
New base stats: 92/92/77/117/112/60(550)
New ability and desc: Rocky Charm(Solid Rock + Cute Charm) = Sylverupt takes 2/3 damage from supereffective moves that make contact
Notable Moves: Ancient Power, Baton Pass, Calm Mind, Earth Power, Eruption, Fire Blast, Flamethrower, Flash Cannon, Heal Bell, Heat Wave, Lava Plume, Moonblast, Psyshock, Rock Polish, Shadow Ball, Stealth Rock, Will-o-Wisp, Wish
Role identification: Sylverupt is primarily a bulky special attacker. It's STAB combo is almost unresisted, except for 3 type combinations and certain Levitators. Even then, it has access to good coverage moves that can make up for that. It can also work as a wall/cleric similar to Sylveon. Although it has lower HP and SpD, it is better at dealing with physical attacks than it's parent due to it's slightly higher defense stat, access to will-o-wisp (or maybe lava plume), and ability.

Parents: Camerupt / Sylveon
Shared egg group: Field
Offspring name: Mega Sylverupt
New type: Ground/Fairy
New base stats: 92/112/107/157/142/40(650)
New ability and desc: Sheer Force
Notable Moves: Same
Role identification: When Sylverupt mega evolves, it's power becomes explosive. Not only is 157 base SpA impressive, but the fact that nearly all of it's usable moves are boosted by Sheer Force makes it even more powerful than it appears. Mega Sylverupt can also attempt to run Calm Mind to boost it's already insanely powerful special stats, Wish to give it a form of recovery to make it a consistent threat throughout the match, or potentially even Rock Polish to make up for it's lackluster speed.

Parents: Toxicroak / Electivire
Shared egg group: Human-Like
Offspring name: Eleccroak
New type: Fighting/Electric
New base stats: 89/124/76/100/85/100(574)
New ability and desc: Quick Reflexes(Anticipation + Motor Drive)=On switch-in, Eleccroak shudders if the opponent has any OHKO or super-effective moves. If Eleccroak is hit by a move that may've caused it to shudder, it will have it's speed raised one stage and take no damage instead.
Notable Moves: Bulk Up, Bullet Punch, Cross Chop, Drain Punch, Earthquake, Fire Punch, Gunk Shot, Hammer Arm, Ice Punch, Knock Off, Poison Jab, Rock Slide, Stone Edge, Sucker Punch, Swords Dance Thunder Punch, Wild Charge
Role identification: Eleccroak makes an excellent revenge killer. Eleccroak is all about the set-up, which he can do very easily thanks to his ability. By switching into a super-effective move Eleccroak gets a free speed boost. Since Eleccroak will be immune to all SE moves the current opposing Pokemon can throw out, it gives it a turn to set-up with Bulk Up or preferably Swords Dance (or potentially even Nasty Plot, which may be doable). Admittedly, Eleccroak does not really have the bulk to take strong neutral hits though, so it’s best switching in on a choiced Poke, or a defensive Poke with one SE attack and forcing a switch out.

Parents: Shuckle / Gliscor
Shared egg group: Bug
Offspring name: Shuckor
New type: Rock/Flying
New base stats: 57/62/187/37/152/60(555)
New ability and desc: Sand Berry(Gluttony + Sand Veil)= While Sandstorm is active, Shuckor will regrow it's berry at the end of each turn.
Notable Moves: Agility, Baton Pass, Defog, Encore, Hone Claws, Infestation, Knock Off, Protect, Power Trick, Rest, Rock Polish, Rock Slide, Rock Tomb, Roost, Sandstorm, Shell Smash, Stealth Rock, Sticky Web, Substitute, Swords Dance, Tailwind, Taunt, Toxic, U-Turn
Role identification: Shuckor will be almost a requirement on any sand team. It's defense is amazing and it's special defense uninvested almost matches it's defense while in the sand. This bulk is scary in it's own right, but once you take into account Shuckor's ability and access to Roost, it's just plain stupid. Under the right conditions, Shuckor can get 75% of it's health back in one turn thanks to Roost + Sitrus Berry. Alternatively, Shuckor can abuse Rest + Chesto Berry to fully restore itself immediately. And the great thing is, even though Shuckor lacks real offensive presence, it's access to Taunt/Encore doesn't leave it vulnerable to set up. One may think that Shuckor is only viable in the sand, but it can make a great lead with Stealth Rock + Sticky Web or a general bulky support Pokemon. Also, if y'all like to play games, you may actually be able to sweep with a Shell Smash followed by Power Trick.

Parents: Lapras / Abomasnow
Shared egg group: Monster
Offspring name: Abomaras
New type: Water/Ice
New base stats: 120/98/87/98/100/70(573)
New ability and desc: Water Warning(Water Absorb + Snow Warning)=On switch-in, Abomaras summons rain for 5 turns, 8 if holding Damp Rock. (Basically Drizzle)
Notable Moves: Aqua Tail, Avalanche, Blizzard, Dragon Dance, Earthquake, Energy Ball, Freeze-Dry, Giga Drain, Heal Bell, Hydro Pump, Ice Beam, Ice Punch, Ice Shard, Leech Seed, Seed Bomb, Surf, Swords Dance, Thunder, Thunderbolt, Waterfall, Wood Hammer
Role identification: For Rain teams looking for a setter, look no further than Abomaras. It has good bulk with access to minor recovery in the form of Giga Drain, Leech Seed, or (rain weakened) Synthesis so it can last throughout the match. Although it's attacking stats aren't the greatest, it does have a good offensive presence. On the physical side, it has access to both Dragon Dance and Swords Dance to boost it's attack and Ice Shard as a form of priority. On the special side, Abomaras can fire off powerful rain boosted Hydro Pumps as well as accurate Thunders, which pairs great with it's secondary Ice STAB.

Parents: Lapras / Abomasnow
Shared egg group: Monster
Offspring name: Mega Abomaras
New type: Water/Ice
New base stats: 120/138/117/138/120/40(673)
New ability and desc: Snow Warning
Notable Moves: Same
Role identification: Surprise! This rain setter is also a hail setter! If you need a hail setter, or for some reason need a hail setter AND a rain setter, you gotta go with Mega Abomaras. It has fantastic bulk and good survivability with Leech Seed, Giga Drain or (hail weakened) Synthesis. Mega Abomaras is also capable of dishing out great damage with it's fantastic attacking stats. It has access to Swords Dance and Dragon Dance, although it's speed is too low to really make use of DDance. Although Mega Abomaras misses both rain boosted Hydro Pump and accurate Thunder, it gains accurate Blizzard and residual hail damage to wear down foes. All in all, Mega Abomaras is capable of hitting hard and taking hard hits, and can drastically alter the match with it's ability to change weathers.

Parents: Nidoqueen / Venomoth
Shared egg group: DNA
Offspring name: Venoqueen
New type: Ground/Bug
New base stats: 90(80+10)/97(77+20)/73/92(82+10)/80/83(515)
New ability and desc: Tainted Lens(Poison Point + Tinted Lens)= Not very effective moves will also badly poison the target.
Notable Moves: Bug Buzz, Earth Power, Earthquake, Fire Blast, Fire Punch, Flamethrower, Focus Blast, Giga Drain, Ice Beam, Ice Punch, Quiver Dance, Roost, Shadow Ball, Sleep Powder, Stealth Rock, Surf, Taunt, Tailwind, Thunderbolt, Toxic Spikes, U-Turn
Role identification: If I'm being completely honest, I'm not entirely sure what Venoqueen's best role is. On one hand, it works great as a pivot with access to STAB U-Turn which due to large amount of types that resist bug, has a good chance to toxic many Pokemon. Venoqueen also has potential as a lead, with access to Stealth Rock and Sleep Powder. Toxic Spikes can even be used if you want a better way of spreading status than just U-Turning all over the place. If one doesn't particularly care about spreading statuses, than Venoqueen can still go as a sort of semi-wall. It's bulk is not the best but it does have access to Roost, and the fact that it doesn't need Toxic to actually badly poison things gives more room for other moves. Finally, Venoqueen can attempt to go Quiver Dance sweeper. Anything trying to switch in to Venoqueen gets punished, and the few types that are incapable of getting poisoned are thankfully weak to it's Ground STAB. Venoqueen's access to a wide special movepool is great, because what may take down a potential threat can also badly poison a potential wall.
