Blitzwing's expulsion from the ranks of the Decepticons is unique in
that it is the first documented case in which an expelled Decepticon,
rather than become a simple independent or non-combatant, instead
joined the ranks of the Autobots. Interviews with Autobots who knew
Blitzwing in this time confirm that there was no trace of the
Corruption in him; some, who had known him before the Corruption, have
said that he was just as they remembered him from the golden age.
Where did this lowly Decepticon Triple Changer find the strength to be
the first of his kind to successfully throw off the Corruption? No
one knows.
