The Tri-Twisters are a team of Chaos Brawlers in Bakugan: Mechtanium Surge. They consist of two brawlers: Sion and Lucas.
Their first appearance is in episode 5, where Mag Mel decides to give these two boys Chaos Bakugan (Cyclone Percivals) and are brainwashed into doing his bidding after they are defeated by Anubias. They soon challenge the Brawlers, but instead of the entire members of the Brawlers showing up, Shun and Marucho decide to take them on without Dan's help. The Tri-Twisters use some underhanded tactics making it seem like the Brawlers didn't have a chance. It is soon shown that the Tri-Twisters had thrown down a third Cyclone Percival into the battlefield, as it was attacking Taylean invisibly.
- They are very similar to the Bash Brothers, because both teams have two male group members, the fact that both teams were hypnotized by Mag Mel and both teams got Chaos Bakugan (Cyclone Percival and Flash Ingram).
- Despite the team only having two humans, they call themselves the Tri-Twisters because they have three Cyclone Percivals.
