The chore of raising a Pokémon in Pokémon Red, Blue, or Yellow is worth it for the bond you share. However, for those looking to battle the notorious Team Rocket or face the Elite Four, having a robust Pokémon lineup is essential.

The first generation of the Pokémon games had the most memorable and unforgettable designs. Pokémon like Charizard and Pikachu became mascots for the series, whereas there are lesser-known Pokémon for good reasons. Balancing made each Pokémon close in combat power, aside from a few exceptions. Master trainers can save plenty of time by avoiding these Pokémon. They give you few experience points in a battle, and they are subpar additions to a lineup.

10 Rattata

Pokemon Go's Rattata anime

Rattata is one of the earliest Pokémon encounters in the first generation games. This Pokémon is much like normal rodents. According to Pokémon Yellow's Pokédex entry, "Will chew on anything with its fangs. If you see one, it is certain that 40 more live in the area." The Pokédex explains that Rattata is common in the Pokémon world. Rarity doesn't mean everything, but this mouse Pokémon is neither strong nor capable of battling the Elite Four.

9 Kangaskhan

Kangaskhan in Pokémon: Let's Go

This ferocious Pokémon is found only in a small section of the Safari Zone. You have to walk deep into the Safari Zone to find this Pokémon, and it doesn't help you have limited steps.

Many of the non-evolving Pokémon in Generation I are weaker than their evolving counterparts. Kangaskhan is a wonderful parent with a temper for those who bring harm to its infant. Despite this, many opt to find a different Pokémon. This Pokémon's stats and moveset are inferior to other top-tiers.

8 Mr. Mime

Mr. Mime in Pokémon: Let's Go

Mr. Mime is a Pokémon that resembles a clown. You probably want to see Mr. Mime at a birthday party, but not amid a battle with pseudo-legendary Pokémon. This is one of those Pokémon that is often overlooked, given its rarity. In Pokémon Generation I, players can find Mr. Mime only by trading on Route 2. The type of Pokémon you have to give up varies depending on the Generation I game. Given that it's a one-stage Pokémon, Mr. Mime is the least desired Psychic-type.

7 Jynx

Jynx

Resembling a woman, Jynx has a purple face and long hair. Jynx has a slight edge on Mr. Mime for being a dual-type Ice-type and Psychic-type, but it's hard to ignore the shortcomings of this Pokémon. It speaks a language that sounds familiar, although people haven't been able to decipher its language. In the first generation, Jynx was a one-stage Pokémon. The design of Jynx has changed slightly over the years, but it still proves ineffective on a lineup.

6 Magikarp

Flailing Pokémon

As a Pokémon with a minimal move set, Magikarp could be considered the worst Pokémon in the game. Thankfully, Magikarp evolves into one of the game's most powerful Pokémon at level 20. The headache of trying to raise a Magikarp is worth the wait to get a Gyarados. Looking at the Pokémon as a single fish with moves like Splash and Tackle, Magikarp falls behind expectations.

5 Farfetch'd

Weak Pokémon

This is one of the many non-evolving Pokémon of the first generation. Farfetch'd is seen holding a spring onion or a leek stalk. Plenty of people are amused by this bird's appearance and mannerisms, but it's the combat power of Farfetch'd that is deeply troubling. The most powerful move this Pokémon can learn by leveling up is Slash, a 70 power attack. Its Normal-type attacks are no match for almost any Electric or Ice-type.

4 Onix

Onix from the Pokemon anime

Onix is one of the first Pokémon to appear in the anime and video games. Never before did we know that a Pokémon could be as colossal. Most assume this is a powerful Pokémon, especially with a Pokémon Red and Blue Pokédex entry that reads, "As it grows, the stone portions of its body harden to become similar to a diamond, but colored black."

For a Pokémon built-up to be as hard as diamonds, Onix falls short of assumptions. An average Squirtle or Bulbasaur can take this Pokémon down with ease.

3 Lickitung

Lickitung Raid Day

Besides being the mascot of a mini-game in Pokémon Stadium, Lickitung has been mostly ignored in the anime and Pokémon games. Normal-types are often sidelined because they aren't super effective against elements. It's normally effective against every element, but it's weak against the Fighting-type. Aside from having a comically massive tongue that it uses as a weapon, there are few ways for this Pokémon to win battles.

2 Tangela

Gen 1 Pokémon

This Pokémon isn't tangled in a knot; this is its appearance. Tangela is one of the most forgettable Pokémon in the Kanto Pokédex. It's a pure Grass-type that cannot evolve. The base stats of a Tangela are low, which is why most trainers catch it for the Pokédex entry, then stick it in a PC box. Compared to other Grass-types, Tangela is less powerful but more mysterious. What is underneath those vines?

1 Zubat

Zubat swarm outsite Mount Moon

Zubats fly in swarms in most caves of the Pokémon first generation games. These bat-like creatures can be frightening to the average trainer, despite being one of the weakest Pokémon in the games. Defeating Zubat rewards players with a small number of experience points. The common theme here is that Zubat is not beneficial to fight with or against. Even if you evolve one into a Golbat, the stat increases are minimal.
