" @Jubilantlad: Ernst turned out to be Cassandra Nova as far as I know....or at least her psyche trapped in that synthetic alien amoeba's body "

" @Danial79: She was one of my favourites, I'm pretty sure she was the saddest to see die :( for me at least "

" Wallflower  :( :(  "

Is the necrosha trade out yet?

CIPHER.

Oh wait, no one knew about her. Never mind.

This thread just makes me miss seeing all those students and the potential they all had. Would've loved to see more of Indra and Trance. Those two had really unique abilities.

So much potential. Gone because status quo always loops around. Only in comics do more young characters die or fall off than older ones.

And more still NEED to die.

@adamtrmm:

Awww cmon, they aren't all bad. Just the lazily created ones that are nothing but a power set.

Yeah, that would still be most of them.

From the living ones on this list I'd still opt to keep Hellion, Laura, Surge, Rockslide, Dust, Anole, Elixir, Mercury and Pixie. Indra just cuz I feel they could do more with him.

Wait a sec, I just checked OP and I take it back, I had different Gens in mind! lol
