But you also have to take size into account. The Bewilderbeast is much bigger than the Red Death, being 520 feet (158.5 meters) long and 160 feet 5 1/2 inches (48.9 meters) tall, while the RD is 400 feet (121.9 meters) long and 99 feet (30.2 meters) tall. And the Bewilderbeast actually has better armor than the Red Death, the Bewilderbeast 38 and the Red Death 30. And dragon fire doesn't seem to faze Bewilderbeasts much, as shown in the final stand-off with Drago's alpha.
