[Marvel] Is there an upper limit to the beings Rogue can absorb energy from?
gpt
Yes - certain beings are sufficiently powerful that they can resist her outright - for example, most proficient wielders of the Power Cosmic would be able to prevent themselves from being absorbed (though doing so tends to be painful).

Another limit to consider is that if she attempts to absorb the powers of somebody sufficiently powerful for too long, she runs the risk of their personality overwhelming her and taking over. She actually struggled with this for a time after absorbing Carol Danvers' (Ms. Marvel's) powers.
