Flytris (フライトリス, Furaitorisu?) is Radizen's Mechtogan and the second Mechtogan used by Marucho Marukura in Bakugan: Mechtanium Surge. He is the 2-in-1 Mechtogan along with Thorak and when combined, they form Duomechtra.
In The Eve of Extermination, he was created by Dragonoid Destroyer along with Thorak using 20% of his powers due to Marucho's, Shun's and their Guardian Bakugans determination to win the battle. He and Thorak later formed Duomechtra and they end up defeating Mechtavius Destroyer.
In Beginning of the End, he was summoned by Marucho and Radizen to help them defeat Mechtavius Destroyer.
- He shares some characteristics with other Mechtogan; his arm blades are similar to Slycerak's, and his head bears resemblance to Slynix's.
- Flytris's Bakugan form has a striking resemblance to Nine-Ball from Armored Core.
