Hyphalosaurus lingyuanensis
Hyphalosaurus (meaning "submerged lizard") is a genus of freshwater aquatic reptiles which represent a major part of the Jehol Biota. They lived during the early Cretaceous period (Aptian age), about 122 million years ago. Hyphalosaurus fossils are relatively widespread in the Jehol beds, which represent a series of freshwater lakes. Several specimens of H. lingyuanensis and thousands of H. baitaigouensis specimens are known from the Yixian Formation, including entire growth series from embryos in eggs to fully grown adults. H. baitaigouensis was originally reported from the younger Jiufotang Formation, though subsequent study showed that the fossil beds it was found in might also belong to the Yixian, though from younger rocks and a different region than H. lingyuanensis. H. lingyuanensis and H. baitaigouensis were largely similar in anatomy, both achieved a maximum adult body size of about 0.8 meters. They had small heads with numerous needle-like teeth, and extremely long tails with more than 55 vertebrae. The primary difference between the two species is the number of vertebrae in the neck. H. lingyuanensis had 19 neck vertebrae, while H. baitaigouensis had 26.

Hellbender Salamander - Cryptobranchus alleganiensis
The hellbender (Cryptobranchus alleganiensis), also known as the hellbender salamander, is a species of giant salamander endemic to eastern North America. A member of the Cryptobranchidae family, hellbenders are the only members of the Cryptobranchus genus, and are joined only by one other genus of salamanders (Andrias, which contains the Japanese and Chinese giant salamanders) at the family level. These salamanders are much larger than any others in their endemic range, they employ an unusual means of respiration (which involves cutaneous gas exchange through capillaries found in their dorsoventral skin folds), and they fill a particular niche—both as a predator and prey—in their ecosystems, which either they or their ancestors have occupied for around 65 million years. The hellbender has a few characteristics that make it distinguishable from other native salamanders, including a gigantic, dorsoventrally flattened body with thick folds travelling down the sides, a single open gill slit on each side, and hind feet with five toes each. Easily distinguished from most other endemic salamander species simply by their size, hellbenders average up to 60 cm or about 2 ft in length; the only species requiring further distinction (due to an overlap in distribution and size range) is the common mudpuppy (Necturus maculosus). This demarcation can be made by noting the presence of external gills in the mudpuppy, which are lacking in the hellbender, as well as the presence of four toes on each hind foot of the mudpuppy (in contrast with the hellbender's five). Furthermore, the average size of C. a. alleganiensis has been reported to be 45–60 cm (with some reported as reaching up to 74 cm or 30 in), while N. m. maculosus has a reported average size of 28–40 cm in length, which means that hellbender adults will still generally be notably larger than even the biggest mudpuppies.

I'm not an amphibian expert by any means, although you stated that the first one has needle like teeth, does the hell bender have any teeth? and is the hell bender a toxic sub-species of salamanders in general?

The disadvantage of having a fight like this:

Eventhough the animals are cool, no one knows about them. lol

Hyphalosaurus lingyuanensis apparently can get 1 meter long, so for now I back the lizard thing lol
