Owain

Owain (ウード, ) is the future son of Lissa, making Chrom his uncle and Lucina his cousin. A man who often acts like a one man theater troupe, his boastful nature and oftentimes bumbling hides a powerful potential.

While he plays the same as Ryoma, Owain has a bigger Magic stat, allowing him to use the Topsy-Turvy weapon attribute effectively, especially with Resonating Power.

Trivia

 * Much like Oboro, Niles, and Navarre, Owain started out as an NPC in Story Mode before becoming a playable Unit via DLC.
