The ability to merge separate powers into a single whole and combine/merge powers to create combos or even to create a new force. Superpower variation of Amalgamation. Sub-power of Superpower Manipulation.
The user can merge two or more powers to create new powers as well as different combinations. Sometimes the second ability may be naturally born, on others it may have been taken from another by force.
The users can even use two or more separate powers simultaneously to use for various uses.
In some situations, having more than one ability spontaneously can be considered rare, or even an impossibility.
In some cases, even though a person possesses more than one ability, they may not use more than one at the same time.
