Magikarp. If you give it an exp. share, It will evolve into gyarodos. I have a golden magikarp right now(i have an action replay code for it. I am not that great,)
I go with feebass, bidoof, magikarp, metapod, pidgey, and ledian.
Magikarp <lvl 15, Silcoon, Cascoon, Metapod, Kakuna and Wurmple
Metapod evolves into Butterfree.
to catch a shiny metapod go to viridian forest and stay in the grass wait till you find metapod keep finding metapod until it glitters.
Metapod, but only if you catch it as a metapod.
Caterpie evolves into Metapod at level 7. Metapod evolves into Butterfree at level 10.
Only Magikarp, get a better one for more variety
Metapod evolves at level 10 into Butterfree.
Metapod evolves into Butterfree at level 10.
To get a metapod, you can either find a caterpie in the Viridian Forest and level it up to level 10 or you can look for a metapod in the Viridian Forest as well. Metapod is a little more rare than caterpie but if you are just determined to get metapod, it shouldn't take longer than a few minutes.
Metapod evolves into Butterfree at Level 10.
Yes, Caterpie evolves in Metapod at level 7
