Aye, king cobra should be considered as human sized creature with it's lenght and overall mass (when speaking full mature one as there can be 18'ft long ones although it's rare to find). Also considering it mostly eats other snakes (including fellow king cobras, which makes mating season interesting times for male king cobras when they approach female king cobra as they are not sure are they lured to be snacks or mating partners).<br/><br/>Also if there is reaction speed enchancing mutation, king cobra definately should have it as they are damn quick when they are striking pose. Also mutation improve stealth when in native terrain (for big snakes they are very hard to spot). Possibly even large mutation and make the snake overall damn lot bigger (as warmer climates = bigger snakes).
