Pieces of broken discs whose internal monsters have already been revealed. These can be used when combining for a specific monster to help you get a desired result. For example, if you get a Gaboo Disc Chip, you can combine two monsters with it as long as at least one of them has Gaboo ancestry, and the Gaboo may still come up as a possible result.
The chips are always colored similarly to the basic monster breed inside (??? sub-type monsters do not get chips) so that they are easier to identify.
Monster Rancher 1[]
In this game, Disc Chips are called CD Fragments, but do the same thing. They can be won at the Winter D, C, and B Cups in Feb, the Spring D, C, and B Cups in May, the Summer D, C, and B Cups in Aug, and the Fall D, C, and B Cups in Nov.
Monster Rancher 2[]
These chips can be used when combining as a secret seasoning.
Monster Rancher Explorer[]
The use of Disc Chips is a bit different in this game. If you can collect four chips, it will create a full Mystery Disc, which will allow you to capture a companion monster on one of the bonus levels and use its abilities to help you beat higher levels.
