I've had the Lab Map for years now, and I just learned the other day that battling him can lead to pets changing genders... I have a few pets I'd like to switch so I went to the Battledome but he's not in my list of challengers. How do I fight him?

Honestly its all about luck, I've also had the lab ray for about 3 years and don't have him as a challenger. its a random event within the lab. just keep zapping!

You can also refresh at the lab page (this one!) until he unlocks. It took me a few days worth of refreshing before he showed up.

Thanks I have been trying for along time to get him  but I wasn't zapping my pets any more soo...  But what about the snow beast?   I can find him either.

Thanks so much guys! I will be refreshing from now until who knows when  :worried:

Breaziecat might be willing to help you with that. She has offered to help me before when one of my my pets  gender changed, but I got lucky and my gender got changed back by the lab ray not soon after. But I guess she's willing to help you like she would help me. Just go to her profile and send her a neomail telling that enitul send you. :)

Thank you, breaziecat has already been in contact with me!

Yeah, I know. :3 I hope things will all work out for you.
