Don't forget Meryl the elf being voiced by Gwen from Torchwood.

Gwen is that much of a cunt in Torchwood any time I hear her voice it makes me see red.

Cheats on her fiance

Tells him, then wipes his memory to clear her own conscience

Almost brings about the end of the world after said fiance who she is still with gets killed by the Big Bad of the first season

Ruins the life of a mother whose son went missing by finding said son even though Jack tells Gwen to stop. The son was swallowed by a portal, comes back aged 40 years and with enough PTSD he spends half the day screaming. The mother later states it was better off not knowing what happened than learning the truth.

I'm still missing things out and that's before getting onto the rest of the cast who were also some of the worst people you can imagine being in charge of anything, let alone acting as the hidden line of defence against aliens and other potential world ending shit.
