Marvel Legends Odin
Odin — he may be the Allfather, but he's not exactly the best MCU father figure. But to be fair, the franchise doesn't exactly have the best track record when it comes to father/child relationships anyway.
Nevertheless, let's take a look at all Odin has done during his tenure as King of Asgard... He conquered thousands of worlds in his prime as a ruthless warmonger, created a monster out of his daughter Hela and banished her to another realm when she became too powerful, and he adopted Loki as an infant to be used as a political tool. Not to mention that Odin was often portrayed as cold, harsh and distant.
