I'm planning on doing a Mega back door roth conversion(401k employer) with after tax contributions later this year. Will the gains taxed as income or capital gains?

Since I can only do this once a year, I will have gains or losses. Will the gains or losses be treated as capital gains or income on my 1099-R?

Ordinary income. Investments inside a retirement account do not receive capital-gains treatment.
