(1) A
Pokemon that cannot learn any moves besides Harden, and tackle if you've evolved it from a Caterpie.
Will evolve to Butterfree at lvl. 10
(2) A useless person who rarely moves outside his house, likes to stay in and his
head is impenetrable to matters outside his computer.
(3) A "has-been." Used to go around doing physical activities, but now stays immobile and lazy. May one day become fit again.
ex.1 "Dammit Joe you're like some kind of Metapod nowadays.
ex.2 The celebrity is now a Metapod, but hopes to one
day be a Butterfree.
ex.3 "You're more
useless than the
time my Caterpie evolved to a Metapod!"
