WWE may have landed themselves in hot water after they filed to trademark the name 'Gunther Stark' - which has ties to a Nazi U-boat commander.
Former NXT UK champion Walter held the belt for 870 days - the longest championship reign in WWE history since 1988.
He now performs on the NXT 2.0 brand in the US and eyebrows were raised after he grabbed a microphone after emerging victorious over Roderick Strong.
