This is Calumon from Digimon. In the beginning of Digimon Tamers (season 3) he's just a cute little digimon wandering around, but in the end you find out that he is actually the catalyst that has the power to make Digimon evolve. He releases the power, and chooses to live the rest of his life as a Digimon.
It took 9 boards, but the 3rd board from the left there was noting on.
