Finally 4chan works again.
I'll give way easier puzzle this time. Not only these 3 Pokemon are connected by 1 thing but also this 1 thing is limited to these 3 Pokemon and no other.
>>23394580 (earlier puzzle)>>23396684Close but it's not it. Voltorb/Electrode can learn Flash by the way.
>>23396817Same as above + what you wrote only applies to half of these Pokemon.
Answer:
These are the only Pokemon unable to learn TM Double-Edge in first generation. In following generations this TM stops to exist.
I could remove Caterpie, Metapod, Weedle, Kakuna, Ditto and Magikarp from the list because they can't learn any TMs in general but oh well.>>23396504I have two.
1. All of these have pretty good base speed but horrible base defence.
2. They all have connection to sleep. Abra sleeps 18 hours a day, Chatot has moves which doesn't let you sleep and Haunter has Hypnosis. It's flawed connection, I know.
>>23396707Another hint needed.
