I got a question for you: Vasudeva I (Kushan: "Bazodeo", Chinese: "Bodiao") was the last of the "Great Kushans." Named inscriptions dating from year 64 to 98 of Kanishka's era suggest his reign extended from at least 191 to 225 AD. He was the last great Kushan emperor, and the end of his rule coincides with the invasion of the Sasanians as far as northwestern India, and the establishment of the Indo-Sasanians or Kushanshahs in what is nowadays Afghanistan, Pakistan and northwestern India from around 240 AD.

Based on this passage, who is the last ruler of kushan dynasty?
Let's think first:
The relevant sentence in the passage is: He was the last great Kushan emperor, and the end of his rule coincides with the invasion of the Sasanians as far as northwestern India, and the establishment of the Indo-Sasanians or Kushanshahs in what is nowadays Afghanistan, Pakistan and northwestern India from around 240 AD.
Therefore, the answer is Vasudeva I.
