A new trailer was just released including Slash - notable passive skills include the beloved crouch jump from Quake 4. Active skill appears to be an Area of effect plasma trail.

"Slash moves through the Arena like the figure skater she used to be, cutting a lethal path through the other Champions. In her skates, she’s a force to be reckoned with – quick, agile and ever-so-deadly. Slash will be part of the upcoming Quake Champions Closed Beta, which starts on April 6. "

More info regarding the Champion.
