Just had a thought, and possibly something to look out for if we get any more pictures of Smash run
This picture was taken from the Smash Bros. direct
As you can see there's 3 (if you don't included warp) powers, Samus's Power Bomb, Meteor Shower = Ness/Lucas PK Starstorm? renamed, Plauntena's Heavenly Light,
Taken from Smash Bros E3 (2014)
Same could be said for that picture but Horizon beam being Paluneta's Mega Lazer and Dual Cyclone being a variation of Meta Knight's Mach Tornado
So what's the point of me bringing this up you ask? Well we have 2 moves belonging to 3 veterans from Brawl, which people seem certain at least 2 of them (Ness and Meta Knight will return), so we might see some possible moves in smash run that could be used by Ridley
Not really much to go off though just came to mind
