On the other hand, monitor lizards, while diverse in size and species, generally weigh less and lack the venom of Komodo dragons. But some larger species like the Perentie can reach impressive lengths and show strong physical abilities. In a hypothetical battle between these two, the Komodo Dragon's size and venom would likely allow it to win against monitor lizards. But larger monitor species might change the game with their strength and could give a tough fight to Komodo Dragon.
