Combustoid (コンバストイド, Konbasutoido?) is a Bakugan Battle Suit in Bakugan: Mechtanium Surge. It belongs to Wiseman and Gunz Lazar. It is Reptak's Battle Suit. It has also been used by Spatterix and Betadron.
Double laser turrets extend out to blast opponents with a powerful thrust. Combustoid has plated body armor to defend against even the most formidable opponents. When fully armored in battle, Combustoid is a force to be reckoned with, as its terrifying spikes give it a huge advantage in battle. 
Combustoid appears with Reptak in Enemy Allies.
A Darkus Combustoid was used by Betadron in Battle Suit Bash.
Combustoid was used again by Betadron in Countdown to Doomsday. It was defeated by Defendtrix.
Haos Combustoid was used by Reptak to battle against a Pyrus Combustoid used by Spatterix in Gunz Lives.
