Pokemon: Nidoking
Mod of Origin: OptiMons
Typing: Poison / Ground
Stats: 81 HP / 112 Atk / 77 Def / 100 SpA / 75 SpD / 105 Spe
Ability: Poison Point / Rivalry / Sheer Force

Competitive Impact: Unfezant is a very fast Pokémon. If it is voted in, it would be ranked as the second fastest mon in the tier, and that is plenty helpful when you are dropping heavy Ate boosted attacks. Its not without flaws however, as Unfezant's only means of damaging Steel types come from Brick Break of all things, its hardwalled by plenty of common mons in Smash, but in spite of that expect Unfezant to keep reminding you of why its the best offensive bird in the tier.

Pokemon: Latios
Mod of Origin: G-Luke's Ideal World
Typing: Dragon / Psychic
Stats: 80 HP / 90 Atk / 80 Def / 130 SpA / 110 SpD / 110 Spe
Mega Stats: 80 HP / 130 Atk / 100 Def / 160 SpA / 120 SpD / 110 Spe
Ability: Mega Launcher [Same as Mega]*
Boosts the power of Pulse, Ball and Bomb moves by 1.5
Notable New Moves: Dragon Rage (Dragon type Vacuum Wave), Hidden Force (Physical Hidden Power)
Shadow Ball - 90 BP
Competitive Impact: Latios is a fearsome wallbreaker from a forgotten time period, and in a Magearna free metagame it has come back to reign! Even though the tier is crawling with Fairy types, only the mega forms can actually outpace it, allowing Latios to be able to smack the rest with a powerful Psychic STAB, and it can go for Choice Scarf to flex on them regardless. If it wants to go mixed (or physical!) Latios can whip out its bulkier Mega evolution.

Pokemon: Steelix and Mega Steelix
Mod of Origin: Movin' On Up
Typing: Steel / Ground
Mega Form: Steel / Dragon
Abilities: Sturdy / Strong Jaw / Sheer Force
Mega Form: Iron Barbs
Stats: 83 HP / 105 Atk / 200 Def / 65 SpA / 80 SpD / 57 Spe
Mega Form: 83 HP / 145 Atk / 230 Def / 65 SpD / 110 SpD / 57 Spe
Notable Moves: Coil, Outrage, Glare, Dragon Rush
Competitive Impact: Another great Steel type to help bolster the meta's defensive prowess, Steelix can help the Electric infested Smash Mod with its important Ground typing. Has Coil if it wants to be a defensive sweeping set as well. Its Mega Form also adds another great Dragon type that can threaten stuff out with its outstanding bulk and power.
