Bubblegum

Bubblegum is the name of a wyvern currently in the service/possession of Bambi.
Bubblegum was first known to be a combat mount of an unnamed Koryo Wyvern Rider who was present at the Liberation of Lu Jing. Bubblegum's rider was killed, and in the subsequent months, Bambi fed and trained Bubblegum to the point of convincing Bubblegum to reside within their extradimensional core space (colloquially known as the pokeball).
The degree to which Bubblegum has been converted to Bambi's loyalty has yet to be tested in a high-intensity encounter.
