Here we are... Kanto and Johto starters. Let's look at Blastoise and Feraligatr in terms of base stats.
HP/ATK/DEF/SpA/SpD/Speed
Blastoise: 79/83/100/85/105/78
Feraligatr: 85/105/100/79/83/78
Hmmm... something's fishy here, right? Now let's look at Venusaur and Meganium... our beloved grassers.
Venusaur: 80/82/83/100/100/80
Meganium: 80/82/100/83/100/80
Wait, what? You're telling me that Meganium is Venusaur with Defense and Sp.Attack flipped... without the poison typing?!
Yes yes, unfortunately, that's true. Now it gets even worse o_O Let's look at our Fire starters...
Charizard: 78/84/78/109/85/100
Typhlosion: 78/84/78/109/85/100
O_O
Wow, really? I'm not lying... go check it for yourselves... Johto starters are a product of Game Freak's laziness... hence why people shrug them off in competitive battles.
And have you really used Unown in a serious battle? Somehow I doubt it...
