"The Coming of Sunfire!"
Sunfire attacks as Beast, Iceman and Angel can not stop him. They follow him down to Washington DC where the team, minus a very injured Beast, tries to stop Sunfire from taking revenge for Hiroshima out on the US Capitol Building. But Sunfire must choose between revenge on a country he considers his enemy or his father who stands in the way of Sunfire's revenge. The choice is made by Sunfire's uncle, who shoots his own brother to get the revenge he and Sunfire wanted for so long, so Sunfire kills his uncle, but it is too late for his father.
