Weedle, Kakuna and Beedrill

#013 Weedle

Weedle: It eats its weight in leaves every day. It fends off attackers with the needle on its head.

Weedle is kind of in the same situation as Caterpie, but personally I would take a Caterpie over a Weedle. Yes, Weedle grows quickly but he is hard to raise because his defense is low (and lower than Caterpie's too). His attack is decent, but his HP isn't high enough to help him out with defending himself and his attacks aren't strong enough to get the job done either unless one is fighting relatively weak pokémon. I personally have never had the patience to train and keep a Weedle long enough to use it/its evolutions against a gym leader because I find that Caterpie-Butterfree more useful.

#014 Kakuna

Kakuna: While awaiting evolution, it hides from predators under leaves and in nooks of branches.

Type: Bug/Poison

Stats:
HP          Attack     Defense
45               25            50

Speed   Spec Atk   Spec Def
35               25           25

Growth Rate: Medium Fast

Hatch Steps: 4,000

Evolution: Level 10

Weaknesses: Fire; Flying; Psychic; Rock; Ice

Strengths: Grass; Bug; Dark

Here we have another "awaiting evolution" pokémon. Kakuna is faster and slightly higher in attack than Metapod, but that's about all he's got going for him as far as stats go. Kakuna, and he still doesn't learn any moves other than Harden. Again, Kakuna is difficult to raise if it isn't evolved knowing attack moves and I would still take a Metapod over Kakuna. Kakuna does, however look like he's wearing a tie and that makes him much more adorable than the other bug pokémon.

#015 Beedrill

Beedrill: Its best attack involves flying around at high speed, striking with poison needles, then flying off.

Type: Bug/Poison

Stats:
HP          Attack     Defense
65               80            40

Speed   Spec Atk   Spec Def
75               45            80

Growth Rate: Medium Fast

Hatch Steps: 4,000

Evolution: Final Stage

Weaknesses: Fire; Flying; Psychic; Rock; Ice

Strengths: Grass; Bug; Dark

(Yes, I know the 1 is backwards...) According to the description, Beedrill sounds kind of like a pansy, but I don't think that's totally true. As you can see here, his attack and special defense sky rocket from his previous evolutions, which is a huge help. He's pretty quick as well, but if one is hit by a physical attack, he's not likely to last long (like most bug pokémon). He is better than Butterfree stat wise, but as far as moves I don't think he's that great. He learns his last move at level 40, and if you are able to keep him for that long, kudos. I never found Beedrill worth training or using in gyms, I only raise one for my pokédex. He looks super awesome, but again, not my top pick for team pokémon, even temporarily.

In summary, some people find this trio worth the effort, but I find that Weedle is hard to train due to low defense and HP, Kakuna, if evolved knowing moves, will not have as good a moveset as Metapod, and Beedrill looks awesome but isn't worth the time or a spot in the team.
