Remember when Drizzle and Drought used to be legendary exclusive too? Now they're not and gameplay is... kinda more fun because of it. Also, Eruption and Water Spout were practically exclusive once upon a time. Things can change.
If offering a new mostly reliable Special Flying move and powerful dragon move that most Pokemon wouldn't want anyway is gamechanging then... so be it. I'll stand by the idea of Stealth Rock and Weather Abilities being much more influential. Guaruntee that most flying types wouldn't care about Aeroblast.
Besides, I have learners of Sacred Fire, Sacred Sword and Seed Flare as level up moves due to the way the Pokemon lives or may have well... sacred swords.
So let's go over in greater detail some of these moves.
Thunderclap rips the earth with a blast of energy and creates well... a thunderclap! It's so loud that the earth trembles and enemies are effected by shockwaves for massive accurate damage: same formula as Earthquake might I add. Of course, many learners are not electric type: Ponyta and its evolution can spring directly to mind as an Earthquakeless non-Electric type that can certainly take advantage of this move.
So we have the Electric equivalent of Earthquake, distributed rather helpfully and it outpowers Wild Charge (well, outpowered, Wild Charge is now a Double-Edge clone. Comparing Wild Charge to Volt Tackle is the exact same comparison of Double-Edge to Afro Break: Afro Break has 1/4 recoil instead of 1/3.)
There's gotta be some check to this other than "Bring Ground type" and the answer may guffaw you: Soundproof
Soundproof Pokemon can add a potentially common move to their immunity arsenal instead of the rare Bug Buzz and Hyper Voice and the slightly less rare Roar. Even still, it's soundproof, every Pokemon has a better second ability, whether its Scrappy, Snow Warning, Sturdy, Reckless or anything else, Soundproof is a second fiddle!
So let's introduce a Pokemon at long last.
Tempalar
Type: Fire/Psychic
Ability: Crusader (Increases damage against Dragon, Dark and Ghost types by 33%, non-cumulative)/Serene Grace
Tutor: Brute Force (All Damage comes from Physical Attack)
Dreamworld: Speed Swap (Switches your base speed stat with the enemy you switch in against)
Gender Ratio: 50/50
Breeding Groups: Humanshape/Mineral
Appearance: Tempalar is a tiny orange creature with a mostly spherical shape. Its rounded head is never seen, covered by a close faced helmet that practically covers its entire body and armor shoulder pads. Of course, these aren't made of Steel wood or rock: many speculate its body is partly obsidian, which is a very sturdy glass. In its stubby arms it holds a sharp and straight edged longsword, perfect for slashing and a small gem comes from the top edge of its helmet and emanates energy.
To be less confusing: a small orange blob covered in a helmet and shoulder pads whose arms and sword extend out from the eye slits on the barbute shaped helmet head.
Evolution: Evolves into Palloidin at lvl 35
Stats: 50 HP/75 Atk/78 Def/35 SpA/70 SpD/25 Spe
Total: 333
Tempalar is an interesting little creature with 4 possible abilities, none of which are bad. Brute Force allows the use of Fire Blast and Psychic to run on a better Stat, while Crusader mixed with one of the Sword based Fight Moves is always helpful for cutting down the darkness. Of course, you'll probably drool over Serene Grace because a Sacred Knight of Fire, has needs for Sacred Fire: and a Serene Grace Sacred Fire will burn everything, no questions asked (unless its 95 Accuracy flubs 1 ot 20 times.)
Of course, when you consider a terrible speed stat, you might want to try Speed Swap, which instantly and permanently (until the Pokemon switch out) swap speeds. If you switch in on a Crobat, your Tempalar will have a base speed of 130, and Crobat will have 25. If Crobat swaps out, its speed is restored next time it comes in. If Tempalar switches out, it will swap speed with the next incoming Pokemon, but Crobat will still have a base speed of 25 until it switches.
A more exacting movepool of Tempalar and its evolution is not complete, but it is filled with Blades and Swords, giving it decently diverse coverage with Night Slash, Leaf Blade, Sacred Sword, and Psycho Cut. All of these moves can serve a useful purpose especially if you can pull off a Sword's Dance.
Palloidin is even more of the same, but by comparison, gains a lot of durability.
Pokedex: Tempalar are said to be on an eternal quest. These passionate knights are said to fight honorably yet without any mercy from their burning might.
