A good question for sure.  At the start most enemies will probably be around Ginyu-Force level up to around Final Form Freiza.  They will be powerful, some with very destructive potential, but the angel will try their best to only let them fight enemies they have a chance against.  Of course not all enemies will follow 'normal' procedures, some will be magicians, others might have strange techniques that make them uniquely dangerous though their power might be below your character's.

So, start of namek saga Vegeta is probably a good way to go?
