Bootleg
Bootlegs are extremely rare versions of monsters that have a different type, moveset, and colour scheme from normal. In battle, they appear with a red name.
Mechanics
On the overworld, bootlegs have a glitchy effect. However, bootlegs can also be the secondary member of an enemy team, in which case they cannot be seen from the overworld. In battle, bootlegs have a red name and differently coloured sprites.
The Glitter type is exclusively found on bootlegs; outside of type-changing moves in battle, it never appears on non-bootleg monsters. Bootlegs can be of the same type as the base monster, in which case a different colour scheme is used to differentiate them.
Rates
By default, bootlegs have a chance of 1/1000 (0.1%). Rogue fusions have a chance of 1/50 (2%) to include a bootleg, and fusion swarms have a 1/10 (10%) chance to include one. Static encounters always have a 2% rate.[1]
Bootlegs also have a higher chance of receiving sticker attributes as they are upgraded.
Ritual Candle
Once the game's main storyline is completed, the player can use the Ritual Candle item to expend a monster in their possession in exchange for a guaranteed bootleg. This bootleg will either be the same species or have the same type as the original.
