I was referring to Tony Isabela(Tigra's creator). He should not have pitched Tigra to Marvel. Instead, he should have kept the character and go to a independent comic publisher to market Tigra. Greer is stuck as Tigra because of Isabela's sales pitch.
I should have been clear on my last comment. I really would had loved to see The Cat as Greer Nelson while Tigra as a someone else.
