"Apologies as it was not easy defeating thousands of frost giants with just the aid of Huginn and Muninn." The God Odin stated.
The fight against the frost giants were still not finished but the God Thor was already leading the warriors of Asgard to victory. When the God Odin saw that the warriors of Asgard can now fight against the remaining frost giants, he decided to focus on another problem that they have encountered. The God Odin immediately sent one of his ravens to the location of the escaped convicts.
Even if the God Odin descended onto his raven, it does not mean that he has descended fully because the body still belongs to the raven. The God Odin's clothes and armor could be seen to be made of dark feathery adornments to keep with the raven theme. He has grayish hair with one of his eyes covered with an eyepatch.
