In Hindu dharma, any yogi can achieve one or more of the eight siddhis. They might sound out of proportion for some. But these, in fact, show some of the superpowers that modern fictional superheroes show in some way.
Hindu dharma talks about these superpowers. These are the Ashta siddhis:

1. Anima

Anima is the ability to reduce the body size, so much so that, one can even reduce one’s size to the atom. Krishna in Srimad Bhagavatam describes this trait as “becoming smaller than the smallest”. In Ramayana, Hanuman has been shown to use this trait while he went to search for Sita in Lanka. The modern-day Ant-Man in the Marvel world also possesses the same siddhi power.

2. Mahima

Mahima is the ability to assume a gigantic form. Krishna in Srimad Bhagavatam describes the property as becoming larger than the largest. When Hanuman burned Lanka in Ramayana and when Lord Vishnu in his Vamana avatar enlarged himself that it only took him three steps to cover all three worlds are some instances of Mahima.
Many modern fiction characters such as Elastic-Girl possess this power.

3. Garima

Garima is the ability to be heavy in weight by will. In Hindu epics, there is an instance when Hanuman increased the strength of his tail such that even Bhima couldn’t lift it. While Bhima climbed the Gandhamadana mountains to get some flowers for Draupadi, he was stopped by a monkey’s tail on the way. He asks the monkey to remove the tail off the road, but the monkey replies by stating that he is old and Bhima should remove it himself. However, even being the strongest person on earth, Bhima couldn’t lift it.

4. Laghima

Laghima is derived from the word laghu, which translates from Sanskrit as small or light. This means the ability to make one’s body light. Flying and levitation are the other powers obtained from Laghima.

5. Prapti

Prapti is the ability to obtain, which indicates the ability to get anything anywhere. We’ve seen Gods creating things out of thin air on various shows based on Hindu epics. This shows the prapti siddhi.

6. Prakamya

It is the ability to realize dreams and get what’s desired.

7. Isitva

Isa in Sanskrit means Lord, so isitva means lordship. It is the power over creation.

8. Vasitva

It is the power to get everything under control, especially in terms of physical manifestations.
Other superpowers in Bhagavata Purana

How can one attain siddhi?

Patanjali talks about attaining superpower in section IV of Yoga Sutras. The verse provides five ways of attaining the supernatural powers:
  • By birth: This is part of the hereditary transfer where the spiritually advanced parents transfer their superpowers to their offspring. It could also be that one can achieve a superpower because of the things they had achieved in their previous lives.
  • Medicine: Superpower can be achieved with certain drugs that have miraculous power. In Ramayana, Sanjeevini herb brought Lakshmana back to life
  • Mantra: Chanting mantra is said to grant powers to the prayers who chant special mantras in Vedas. It is because of the power of those words and the self-discipline that chanting of the mantras can bring.
  • Penance: Penance can clarify the mind that one can simply control the five elements by a wish.
  • Samadhi: This is achieved when one achieves unity with the consciousness that extraordinary powers can be obtained.
