|Powers and Abilities|
|First Appearance||The man who laughs|
Joker is a humanoid alien with the same height of a human. He has green eyes and his color is black and white. His appearance is similar to harlequin. He doesn't seem to have hands but smoke instead. The Ultimatrix-Symbol is on his chest.
In Charles 10, he looks the same but with the color scheme of Firstartman's Joker (because Charles usually wears red) and a red spade on his head. The Polytrix symbol is on his shoulder.
Powers and Abilities
Joker has a strange ability: He can change the smoke from his sleeves. He can change the density of his hands. They can transform into claws, swords, even working guns. He's also very quick and agile.
In Charles 10, he can shape-shift his entire body, even to the point of making himself invisible.
Joker just likes jokes but don't really know where limit is and is there for also a very dangerous ally. But the more Ben uses him, he gets better control over the black alien.
In Charles 10, he has natural reflexes to attack or distract his opponents if they attack him, so he is even harder to control..
