Ryan Durand is one of the developers of Scribblenauts, and appears as a character in Scribblenauts Unlimited.
When spawned he will create a Sentient Gargoyle. After some time in the world, he will spawn a storm cloud that rains money.
Rarely when spawned he will have a the head of a falcon, possibly an injoke about how his hair looks like a falcon.
In Scribblenauts Unmasked, he wears a Red Lantern suit with an added ring shine effect. He also has the ability of flight. His rare falcon variant can still be spawned, also wearing the Red Lantern outfit.
