>>44822546Normal has resists. Resists with high DEF at that. Rhydon and Golem.
Psychic is the most overpowered type because nothing resists it except Psychic; SPECIAL is a thing in Gen 1 which is hilariously broken, and Psychic [the attack] can drop SPECIAL so it can beat it's own counter.
And guess what type has the highest special? Psychic.
Also; Chansey isn't good in Gen 1 because it's Normal-type lol. Chansey won't go anywhere near a Normal-type move with a 10-foot pole.
Snorlax is good but not godly as it gets worn down due to Speed, and Tauros is good for more than simply being Normal-type. [It can actually make use of special moves with Gen 1's Special stat to get past Rhydon/Golem]
Also; on the Psychic spectrum we have Alakazam; Starmie; Exeggutour; Slowbro; Mew; Mewtwo... there's far more powerful Psychics than Normals.
