PK3: Battle Frontier Uncatchable Pokemon ᅟᅟᅟ

Pokemon Emerald introduced an array of post-game battle facilities, which is hosted on the island called Battle Frontier.
Besides roping in the existing Battle Tower from Pokemon Ruby & Sapphire, the newer facilities hosts various challenges and rules,
unique to their own facility and differentiates them from the traditional Battle Tower (and each other).

In 2 of the facilities, namely Battle Pike and Battle Pyramid, it is possible to encounter wild Pokemon, and none of these can be captured.
(and to totally break you, these Pokemon can be shiny. *sad* )

@jojo12100 grabbed all these Pokemon straight from the RAM, and used @BlackShark's tool to decrypt said Pokemon.


Below illustrates a comprehensive list of what Pokemon are available, and another complete list of Pokemon can also be found here
