Frank has only a few types of attacks: brandish a knife, come out swinging, and say something nasty. When he brandishes a knife, it causes a lot of damage. Come out swinging is not as powerful. Saying something nasty will lower your guts stat (reducing the likelihood of Smaaaaash attacks).
This battle is much easier if you level up to level 8, because that's when you learn your first psychic attack, PSI Rockin α. You can defeat Frank without that ability, but it's going to be a challenge.
If you don't have Rockin α, heal up if you're at or below 30HP, and just keep bashing away until Frank is defeated.
Bring some good healing foods into this battle, because you'll need them whether you have PSI Rockin Alpha or not. You can use PSI Lifeup Alpha if you want to, but it might be best to conserve your PP so you can use PSI Rockin α (if you have it).
Technically, you should be able to defeat Frank when you're still at level 1, but it would be a challenge. However, to beat Frankystein, level 5 is about the lowest level that gives you a reasonable chance of defeating it.
When Frank is defeated, Frankystein Mark II will attack.
