So was the Ju88, A-20, B-25 and P-61 - none of which, were designed for the role.
Also claiming that other twin-engined aircraft were based on the Bf110 is sadly being misinformed.
Virtually every nation that designed and manufactured aircraft in the 1930's had a twin-engined "heavy fighter" concept at one point or another. It was the natural prograssion in aerial combat thinking, much like the heavy bomber could "get through" unescorted.
The French had the Potez 630, the Italians had the SM.91, the Soviets had the Pe-3, the Japanese had the KI-45 and J1N1, the British had the Whirlwind and Beaufighter, the Dutch had the G.1 and the list goes on.
Virtually ALL of these heavy fighters had their roots in the mid/late 1930's.
