Unstable Bodily Transformation is a bodily reaction exhibited by its practitioners, caused by converting their special abilities to natural energy, sometimes of their unique attributes. This results in increased abilities similar to Nature Mode and the ability to perform various shape-shifting feats. This mode is a multifaceted ability that permits them to achieve feats ranging from creating various weapon-like appendages to even consuming other Bakugan, Bakugan Traps, Mechtogan, and Battle gear, as well as a general increase in their overall capabilities, such as in strength, speed, stamina, reflexes, perception and durability, along with abilities unique to the user which can only be accessed via this mode. When using this mode, the user's body may change dramatically, the most common change being the multiple veins spreading across the entirety of the body of the user.
However, once transformed, the Bakugan experiences a devastating side effect; (Bakugan Traps and Mechtogan are immune to this side effect.) It shall become irrational and slowly lose its mind, slowly but surely pushing it towards insanity. This technique eats away at the mind and personality of its user, driving them to madness if used for too long. If the Bakugan has a Mechtogan, It won't experience this side effect.
If a user successfully gets over the side effect and completely masters this mode, They can "give" this mode(Forcibly or not) to another Bakugan/Bakugan Trap/Mechtogan by coming in physical contact with them. However, the contact has to last for at least 3 seconds. However, this is not the case with users that have been refining their modes for millennia, such as Name1.
Compatibility with one of Name2's Transformation in turn means one is compatible with the Overlord, allowing him to transplant his own flesh and will into their bodies and vice versa.
Name1 is so adept at this mode that it can bestow this mode without physical contact. These specialized methods temporarily bind the target upon application, spreading across their body to restrict their movements while the 3 second countdown starts.
