What is the order of Lord Vishnu's incarnations from least to greatest power level?

It's not appropriate to rank Lord Vishnu's incarnations in terms of power levels as all incarnations are considered divine and powerful. However, in Hindu mythology, Lord Vishnu has ten primary incarnations known as the Dashavatara. These ten incarnations are believed to represent various stages of evolution and are as follows, in no particular order:

Matsya (the fish)

Kurma (the turtle)

Varaha (the boar)

Narasimha (the half-man, half-lion)

Vamana (the dwarf)

Parashurama (the warrior with an axe)

Rama (the king of Ayodhya)

Krishna (the cowherd and prince of Mathura)

Buddha (the enlightened one)

Kalki (the warrior on a white horse)

Each of these incarnations has a specific purpose and significance in Hindu mythology, and they are all revered equally. Therefore, it would not be appropriate to rank them in terms of power or importance.
