After I beat Elite Four Lorelei, I arrived at Bruno's room next. I challenged him there and he sent out his Onix and I battled it with my Blastoise's Surf attack. Onix was defeated and then I had to battle Bruno's Hitmonlee. I used my Raichu against it, but I had a tough time since none of Raichu's attacks was super effective against it. I defeated it after some trouble and then I used my Alakazam against Bruno's Hitmonchan. I defeated it with a single Psychic attack and then I battled against Bruno's Machamp. I beat it with another Psychic attack, but I decided to withdraw Alakazam and I used my Blastoise against Bruno's last Onix. That battle ended thanks to my Blastoise's Surf attack and I saved after beating Bruno.
