I have my own weirdest evolution list...:P
here:
Venonat > Venomoth
~its weird for me,Moth is from a hairy bug?
Exxegcute > Exxeguttor
~LOL! egg to tree??? and exxegcute have 7 eggs,its fit on 1 pokeball????and when it evoles to exxeguttor it only have 3 heads with different emotions...
Magikarp > Gyrados
~what the......fish to sea dragon???unbelievable!
Chinchou > Lantern
~ohhh...its a cool pokemon because its water and eletric type but its weird to me :P
Carvanha > Sharpedo
~Piranha to shark??? but yeah its a cool pokemon and one of my favorite....but Piranha to Shark???no :P
Barboach > Whiscash
~Imagine an eel grows into a whale??? woah woah thats a lie......
Clamperl > Gorebyss/Huntail
~Hey hey!!!!A clamp with a head transforms into an eel and a sea horse???
Bagon > Shelgon > Salamence
~OMG!!!! bagon to salamence was beeter ,but they add shelgon(like a bug type pokemon,caterpie > metapod > butterfree) hes a dragon type not a bug type...come on.......
Snorunt > Glalie/froslass
~Snorunt to Glalie looks better because snorunt looks like only a face glalie too but froslass have feet!!!OMG!!!!!
Magnemite > Magneton > Magnezone
~Magnemite to magneton was cool because the true evoling for it is to combine 3 magnemites,but in games,it just evolves,but,magnemite is 1 then become 3 when it was magneton now,but when it evolves to Magezone,it become 1 again???
well,thats all some pokemon is weird to but some users said it.....
and btw koffing > weezing is not weird,in the game yes,its weird but it anime,it evolves using 2 koffing to combine ( like magnemite > magneton) but im wondoring how James of rocket evolves his weezing,but i readed that he only have 1 koffing and then it evolves to weezing....
