|Transforms into||Any Neutral Vivosaur Excluding Super Revival and Dynal|
|Transforms into||(FFC only)|
|Transforms into||Any Boneysaur excluding Salada|
- While both Shanshan and B-Tricera have Transformation skills, they are not of the Transformation Class, as classes were removed in FFC.
- Any coloration changes, stat increases, and possible Super Revivals from Silver and Gold fossils do not apply to the Vivosaur's transformation. (e.g. Proto with a Silver Body fossil applied will not retain its +20 HP and +10 defense boosts upon transforming into Tricera; Guan with a Gold Fossil applied will transform into a normal T-Rex instead of a T-Rex Lord.)
- The Transformation class has the least amount of vivosaurs than any other Vivosaur Class
