Spike (his daughter's pet) was discovered by the anti-alien Children of Liberty patrol, identified by their barking dog. The organization assumed that the family living in the house were the aliens and attacked them. His daughter pleaded Spike to help. Spike transformed into a dragon and scared off the organization, raging across the streets of National City. Supergirl eventually calmed Spike down and he reverted to his lizard formh and return to his owners.
