Basic Info

Sirius is the 100th number brawler and also one of the two Ultra Legendary Brawlers in the game. The guy is a total menace with a decently high HP, long range attacks with a moderate damage output and immense utility with his Super. Sirius is from the Controller class and has a normal Movement speed of 720 which is rather fast. What makes him so impressive are the shadow summons that feel quite overwhelming when you are the one facing a Sirius in your match.

Trait

Sirius’ Trait grants him a unique ability that lets his Super charge automatically over time and not just by dealing damage to the enemies. You can relate his trait to that of Darryl. This trait gives a benefit that charges his Super up to 75% in just 1.33 seconds. This trait applies just to his Super and not Hypercharge.

Ultra Trait

Sirius’ Ultra Trait grants more of a control ability using which he gains shadows through his attack, spawn and control them. Every fourth damaging hit from a Starr Bomb or Shadow Strike will collect a Brawler Shadow that matches the enemy brawler hit. Sirius can hold up to three Shadows and the amount of collected shadows will be displayed under the Super button. The shadows that Sirius summon gain the same attack and movement speed as the same of the Brawler. If the brawler has multiple forms, the created Shadow will match the form when they were hit.
