Hello, I'm an expert in the field of professional wrestling history and lore. Let's delve into the relationship between two of WWE's most iconic characters, The Undertaker and Kane.

The Undertaker, whose real name is Mark Calaway, and Kane, whose real name is Glenn Jacobs, are not real brothers in the traditional sense. However, they are connected through a storyline in WWE, where they were portrayed as brothers. This storyline was a significant part of their characters' histories and was used to add depth and intrigue to their on-screen personas.

In the WWE storyline, Kane was introduced as the illegitimate son of the parents who abandoned The Undertaker, making them half-brothers. This familial connection was a key element in their feuds and alliances throughout the late 1990s and early 2000s.

Outside of the ring, Mark Calaway and Glenn Jacobs are not related by blood. They are colleagues and have worked together in various storylines and matches, but they do not share a familial bond.

In summary, while The Undertaker and Kane were portrayed as brothers in WWE's fictional universe, they are not real-life siblings.
