Lizard vs Deathstroke vs Spider-Man Doppleganger
Doppleganger-Doppelganger was at least as strong as Spider-Man (able to lift 10 tons). Estimates put him in the 15 ton range.
Powers: Besides his strength, Doppelganger also had claws on all his appendages that allowed him to climb walls.
Lizard-As the Lizard he has superhuman strength, speed, agility, and reflexes equaling that of Spider-Man. He possesses great resistance to injury surpassing that of Spider-Man in that his tough scaly skin is more resistant to being lacerated or punctured by concussive force. The Lizard can also regenerate damaged areas of his body, even to the extent that he can regenerate his limbs and tail if severed.
In addition to this, the Lizard's tail is superhumanly strong and can whip at up to 70 miles per hour. He can scale walls almost as well as Spider-Man can, and can telepathically control all reptiles within a one mile radius of himself.
Deathstroke-Increased mental capacity, quick reflexes, regeneration, immortal, strength, stamina, artificial eye sees in infrared vision
