Ephnol

Ephnol was an alien and a war criminal.

The bounty hunter Deathy tried to catch him and locked him in time.

Ephnol could contact another crimal Skak. Skak tried to set Ephnol free, which caused the house of the O'Brians and a victorian house to swap places in time. Deathy could catch Ephnol together with Sarah Jane Smith and her team and put the houses into the right time again. Deathy took Skak and Ephnol with him to bring them to trial for their crimes.
