| #085: Krona
46 ft. - 14 m. (Large)
Krona's great Attack isn't hampered from the SZ. Powerful enough to be considered the T-Rex of the seas.
A large Water-type Vivosaur that's effective when attacking from long range. It's a rival to the Fire-type T-Rex.
The largest sea carnivore was crocodile-like in looks and diet.
Its biting power was stronger than even the tyrannosaurus.

- Krona was designed with Roman numerals covering its body because of its species name, Kronosaurus, meaning "time lizard." 
- Krona's Silver Fossil integrations change its colors in a same or very similar manner as T-Rex's - likely being a homage to it being the "T-Rex of the seas".
- Krona and Mapo can both be considered T-Rex's Water-type equivalents. Krona is called the "T-Rex of the Sea", while Mapo has similar stats, and Super Evolves into a similar Super Evolver.
- Krona is the only pliosaur (short-necked plesiosaur) vivosaur.
- Krona shares similar moves and the same victory cry with Shoni despite them being unrelated.
