Double Bomb

Double Bomb (also known as DoublevBomb in the SNES/PS version) is a dual tech used by Lucca and Robo in. This dual tech deals fire damage like most other "explosive" techs. It is learned after Lucca and Robo learn Megaton Bomb and Proximity Bomb respectively.

Description
Lucca throws a small bomb at Robo, who then absorbs the energy spins around while adding his own proximity bomb energy to it. Robo then allows for the energy to build up around him, and then releases it in an outwards wave.

Name Origin
Since two techs involving "bombs" are used, this name fits.
