ThunderbirdHow to get Thunderbird
Open the DLC content
Own and install Risen Ballbylon and complete the base game. Beast is a new DLC base ball. Lightning is a base-game ball. Check DLC access →
Get both ingredients to level 3
Obtain Beast and Lightning when offered in your run. Choose each ball again in level-up upgrades until both are level 3. Merely holding both balls is not enough.
Select Thunderbird at a Fusion Reactor
Pick up a Fusion Reactor when one drops and choose the Thunderbird Evolution. Look for the exact target name rather than trying to create a regular mixed fusion. The finished ball should be named Thunderbird.
What Thunderbird does
Attaches to an enemy and damages it every second while emitting lightning that damages nearby enemies.
Use & limits
The attached target takes the recurring contact damage; the lightning is local to nearby enemies. Do not treat the lightning as damage to every enemy on the field.
When to choose it
Choose Thunderbird when you want one attached target to be a source of damage to a nearby group. Its effect makes enemy proximity relevant, rather than relying only on another free-flying hit.
If the Evolution is missing
Check the exact ingredient pair and both current levels. A recipe sharing one ingredient is a different target: check that both selected names match Thunderbird’s pair. If an ingredient has not appeared, it is still missing; no fixed drop time, minimum reactor count or guaranteed offer is implied.
If its effect looks different
If a distant enemy is not taking lightning damage, check whether it is near the attached target. The lightning affects nearby enemies.
