Lonnie would do well and if this was him in the earlier appearances, he would have a good chance of winning this convincingly. The problem is that he has a bad heart, and can not exert himself fully without going into cardiac arrest. King Shark wins for now.
Sorry I just read that King Shark was recently upgraded in strength. Lonnie hasn't got a chance in hell even at his best. I wonder how well Namor would do against KS?
To be honest I did a wiki search on him, and it said that he got an upgrade. I cross referenced it with Comic Vines bio on him and it says that he is a class 100. He may just be out of Tombstones range. I thought that KS in his first appearances would have been a decent fight for him, but now i just think that KS is more of a good match up for Namor.
That's what I thought as well, but apparently KS is a class 100. i never knew this and only read a couple of his appearances in the pre DCnU Superboy run. But that's what it said about him. If I didn't read that bio on him I would have said exactly what I did in my first post on the subject. Maybe DC downplays him? Look at what Marvel has done to the Rhino.
I've never seen KS do anything close to class 100, but I have only read his appearances in Secret Six and Suicide Squad. The pic I showed was from Suicide Squad, but I could be wrong.
