He has been hugely mistreated and cast aside during the last two decades, and is, in a way, ripe for slaughter under Nu Marvel.
But he was treated very, very respectfully in the recent handbook, and, if you read the CW Battle Damage report, you know that many villains and former villains are being considered for SHIELD employment as registered agents by Tony Stark.
So Tiger Shark, who has had well-documented periods of heroism before, may find that Tony approaches him and helps him control his human-to-shark mutation, and asks him to join. Certainly, an underwater team of heroes will be needed, including Stingray, so why not Todd as well?
Regardless, if he's going to be chopped up for fish bait, your appeal is coming wayyyyyyyyyy too late. It's already a done deal.
Orka's death was utterly pointless and so indicative of Nu Marvel. They just brought him up from the watery ranks, dusted him off, introduced him to a new generation of readers, made him viable...and then they kill him. Ho Ho Ho. What a waste.
That's why I've dropped HFH and will encourage others to do so too...seeing
the Man-Ape in a terryclothe bathrobe was clearly just the beginning...and the Reaper's head in a toilet. I'm surprised the artist didn't include a 'floater' in the john just to make the Reaper's indignity all that more undignified. Marvel is not above that these days.
