Would you like to go on a journey?

Oof what to nickname it. What is the gender rate of the Pokémon by chance? 50/50 or is it slanted one way(like more male than female or vice versa).

Well I have six females already... Time for a male to join this harem team. Think I'll call it Bruce after a particular Bat. Unfortunately this means Mavis has to go to my Box and Bruce joins the team at what level? 10 feels appropriate but I'm open to something lower like 7 or 8. I need to train Astrape against these Bats to raise her level a bit before I inquire about the Trainers. Thinking level 7 → 9. Might even try to do Amphitrite and Terra too with 8 →9.

Level 8 it is. What moves does he start with? Bite I know but what else does it have?

Solid. I rolled a 3 so it gets Strong Jaw. STAB Bite.. oof 135 power.

Astrape(Tynamo), Terra(Drilbur) and Amphitrite(Eevee). Bruce(Mangal), I suppose could use a level too, pulling them to 9 if I can. After that, going to inquire about Trainers.
