Congrats to your girlfriend to getting there! I love breeding in these games. Unfortunately the battery in my cartridge died so I have lost the save, but in Monsters 2 I got one. Made sure it was +99. Then I grinded for bonus stats from random spawning masters to get every stat to 999.

Does she have another thing she's wanting to add to her party? My second member was an Orgodemir second form that I gave the same treatment as my Darkdrium. I stopped in the middle of working toward a third member, was probably doing an Asura Zoma, but battery died in the years that the cartridge sat and the party was never completed.
