D-Thundaga (Dサンダガ D Sandaga, lit. "D Thundaga") is a technique in Kingdom Hearts Re:coded. It allows the user to drop lightning on foes.
Mechanics
D-Thundaga is a D Magic Type Overclock Finisher. When activated a ring of lightning appears which can be guided around the field with the D-Pad. Pressing 
allows Data-Sora to to drop a single fork of lightning on the ring, harming enemies near, and holding down intensifies the lightning at the cost of slowing down the speed the ring can move. Lasts for 15 seconds at MAX, 11 seconds at LV3 and 6 seconds at LV2. D-Thundaga lasts longer, moves faster, and has a larger attack range than D-Thundara.
