Weapon Sets
In Splatoon, weapons come as a predefined set. For example, the standard Splat Roller comes with the Suction Bomb and the Killer Wail as its sub and special weapons, respectively. You cannot have a Splat Roller with the Seeker and Inkstrike, as there is no predefined set for the Splat Roller that includes the Seeker and Inkstrike.

However, there are alternates of certain classes. An example of this is the Krak-On Splat Roller, which uses the Squid Beakon and Kraken rather than the Suction Bomb and Killer Wail that the classic Splat Roller sports.
