2015 article says the director of Frozen said Anna and Elsa's dad washed up on the jungle shore and had a 3rd kid, Tarzan. They do appear to resemble each other. I don't remember if we've actually seen any of the Disney characters visit each other's worlds yet outside summons. If we won't see Deep Jungle it would be amazing to have him show up in Arendelle.
If not as a permanent fighter or part of the main plot, in the very least making him a supplemental summons (like Tink) would allow him to fight alongside his older sister Elsa (since nobody else in Frozen is really suited to battle heartless). talk2ty 17:31, September 8, 2018 (UTC)
