 When Larfleeze refuses to release the entity from the power battery, Hammond simply swallows the whole battery and is transformed into the host for Ophidian.It is implied that Ophidian doesn't like Larfleeze very much (possibly because he kept it trapped in his battery), and Larfleeze seems quite concerned about Ophidian's freedom.Ophidian also implies that it is going to "get even" with Larfleeze.
