Felic
From Tardis Wiki, the free Doctor Who reference
Felic was one of the Zygons that crashed their spaceship in the Lake District in September 1909. When the Tenth Doctor was captured, Felic used Zygon body-print technology to impersonate him. Felic attempted to trick and capture Martha Jones, but Martha hit his head with a paperweight, knocking him out. He later came round and attacked Martha again, before committing suicide by destroying the transceiver used to lure the Skarasen, electrocuting him to death.{{Infobox Individual
