>>27087773This guy in giant chasm in Black, mostly because he was such a pain to catch, had him down to 1hp and paralyzed using dusk balls at night, stilled refused to stay in the ball until after 30 balls. Lvl 65 and all, quickly evolved him into Metagross.
Did catch a Metagross there shortly afterwards but it didn't put up as much of a struggle as this fucker.
Harder to catch than any legendary in my experience.
