Mato's design of Raticate, just so freaking adorable.
Raticate, a well-known yet underused Pokemon in the series if you think about it. The most fame it literally got from the games was a Youngster Joey memeing about his special Rattata and Blue Oak giving up on Raticate after finding it too weak to be on his Pokemon team, some assuming that he released it back into the wild. However in Pokemon Adventures, everything changed as Raticate is not only one of the major team members of Yellow's party, it was her very first Pokemon she caught as a Rattata thanks to a fateful encounter to Red. Since then I struggle to wonder how did the first Pokemon Adventures Artist, Mato, made Raticate look so freaking cute. Have you seen Ken Sugimori's work? It looks like an accurate representation of a hostile rat about to bite you. Here in the picture above, he looks like your best pal. Weird huh?

My Super Special Awesome Raticate
Raticate
Item: Flame Orb
Ability: Guts
Nature: Jolly Nature (+Spe, - Sp. Atk)
EVs: 252 Atk/252 Spe
Facade
Sucker Punch
U-Turn/Pursuit
Protect/Swords Dance
So Raticate's favored playstyle since abilities were introduced is making use of it's ability with Guts which of course involves Facade and Protect but for those who want the extra fire power, Swords Dance is good too but some might not prefer to waste it on Raticate since his speed isn't that good to outspeed a lot of Pokemon but if successful, Raticate's Facade hits like a truck, able to one-shot a Garchomp... if you find a way to outspeed it. I don't know about you but I bet Raticate would be a lot more viable if GameFreak increased his speed. Honestly it's through this Pokemon, you see why Smogon tiers were created, to give Pokemon like Raticate a fighting chance.
My Super Special Awesome Doubles Raticate
Raticate
Item: Mago Berry
Ability: Guts
Nature: Jolly Nature (+Spe, - Sp. Atk)
EVs: 252 HP/252 Spe
Final Gambit
Super Fang
Protect
Toxic
So this is an annoying Raticate set but it's only as efficient as the team... as in you literally need to build a team partly around Raticate. Specifically have a "Follow Me" Pokemon in Doubles because obviously the chance of this Pokemon still getting one or two-shot is pretty high in doubles.
FEAR Raticate
Raticate
Item: Focus Sash
Ability: Guts
Nature: Jolly Nature (+Spe, - Sp. Atk)
EVs: 252 HP/252 Spe
Counter
Endeavor
Quick Attack
Just for fun, it's only as viable as the gamble itself. Well I suppose sending out Raticate is itself a gamble.
