Thunder Blade (Pedang Halilintar) is the upgraded version of the Lightning Kris.
- Like the Lightning Kris, BoBoiBoy throw it to his foe, but this one lasts longer than the previous one
- Like it previous form, it can also makes a fire, but unlike the previous one, its only need the tip of the blade to make a fire (Season 1, Episode 6).
- The differences between Lightning Kris and Thunder is the its longer, bigger, more pointed paers and color red.
- When the Lightning Kris was upgraded to Thunder, we notice that BoBoiBoy can hold it for a long time, even when it was already used in attacking.
- Despite being called Pedang (Sword in English), it's more like a bigger Kris than a sword.
- In the youtube english version, it is called Thunder Blade, (Thunder Blade is more appropriate to call this ability of BoBoiBoy because it doesn't really looks like a Sword at all, hence because of Thunder Bolt and the edge is a shape of a blade).
- BoBoiBoy threw the Thunder Blade into the sky which make the clouds rained thousands of Thunder Blades.
