Rasengan is a compressed ball of Chakra that rotates at a high speed in the palm of the user. Rasengan is an A-Rank technique, but many other or its variants are far stronger.
Here are the Top 10 strongest Rasengan variants that we’ve seen in the series so far.
10. Absorption Rasengan
So let’s start with the Absorption Rasengan. This technique was developed by Naruto Uzumaki, when in the 9 Tails Chakra Mode. He creates a Giant Rasengan with chakra arms, then grabs the opponent with another pair of chakra arms and smashes them into the Rasengan.
9. Planetary Rasengan
Another technique utilized by Naruto in the 9 Tails Chakra Mode, where he creates a Giant Rasengan, which is further surrounded by three more regular sized Rasengan revolving around it.
This technique is strong enough to even slow down the recovery rate of the Reanimated Ninja.
