Emerald-Steven
The other games were easy, but in emerald, oh god.... I would destroy his entire team, till it came down to metagross and someone else, the other pokemon would KO 3 of my pokemon, then I would KO it, then metagross would come out and finish me
Worst part, I was way higher leveled than him, and he still destroyed me
So I came back when I felt bored, I had grinded since, he destroyed all but my rayquaza and swampert, it was 2 vs. 1 (metagross) metagross OHKO with meteor mash on lv. 89 rayquaza, and gets lv. 7? Swampert to red hp, EQ crit. After a million tries, I win
