Well, it depends on the skill points. If you still don't have over 50 skill points for each category, you will still have a universal character when your tamagotchi evolves.
Next time really work on the games and going to school a lot.
You need quite a lot of Skill points if you don't want a universal character. Try playing loads of games and sending them to school a lot each day.
It is not unusual, actually it's very common, and if you have a V4.5 then universals are not really bad after all you could get a Mametchi from universals (on V4.5)
Hope i helped, and have a great tama-talking day!!!
no it isnt unsual to have a universal teen then a universal adult. to stop it from becoming a universal next time play with it regularly dont nglect and make sure the wait is healthy and has good skill points. then you'll get a better charactor
