He is voiced by Frank Welker.
Legends of the Multi-Universe (Menslady's Story)
He and Mickey always enjoyed spending time with their father and hearing him tell them about the Angels of Disney (though they were not aware it was the phony story). One tragic day, Oswald was captured by Universal Studios and eventually ended up in the Cartoon Wasteland.
During the Toon/Anime War however he allowed Myotismon to join him and because of this corruption took him and became the just as bad as Emperor X was in the war. He showed that by killing innocent people during the war.
When the Children of the Autobots found Oswald, he was steamed to hear about the death of his father, and at first would not help them to free Emperor X, who was under a spell cast by Jack of Blades. But thanks to some encouraging words from Angemon, Angewomon, Tails, Cosmo and Blaze...and some love from Blaze...Oswald is more than willing to do all he can to protect the Angels of Disney so they can save the universe, and the toons of the Cartoons Wasteland will be welcomed back among the toon race.
Oswald tries to forget the past but one cannot just simply just "forget" and one can never truly move on from the death of a loved one because there is always a lingering pain. Even when the war ends Oswald will always miss the ones he lost during the wars like Ortensia or his father.
