Sean Macbeth

Sean Macbeth is a cranky toddler appearing in Monster. He has the ability to morph into a nightmarish version of The Very Hungry Caterpillar.

Power and abilities
His three-ounce morph is described as having a red and misshapen head, with yellow eyes and green pupils. He has purple antenna and grows to be longer than twenty feet. When he first morphs, he has no mouth or legs, but these eventually appear, with the mouth being ringed with razor-sharp teeth. This morph closely resembles The Very Hungry Caterpillar, so presumably this was his favourite book that he often teethed on.

Appearances
Sean finds a chip of the meteorite ASO-2 and starts sucking on it, as he is teething. His sister Delia takes it from him, but gives it back when he starts bawling. Later, he swallows three ounces of it, making him one of the most powerful morphers. When Delia gets distracted and forgets to feed him, Sean morphs into a giant caterpillar-like creature and eats the kitchen, before moving on to areas of his town. He is eventually blown up by the military.
