There’s a character named Ness who has appeared in the Smash Bros. series up until now, and Lucas is very similar. They are from the same family of PK users.
But Lucas’s physical combat style is quite different. By which I mean he doesn’t have the same standard moves.
His strong up attack is a mentally-powered flip kick.
The finish of his back air attack is a meteor smash.
Oh! Is he grabbing the edge with his rope snake?!
Side Special Move: PK Fire
This is also quite different from Ness’s.
It flies perfectly sideways, even in the air.
The flame pillar explodes!
Standard Special Move: PK Freeze
If you charge it up and control it...
...you can freeze your opponents!
And even more threatening is his PK Thunder. For those of you unfamiliar with the last game, or the one before that, remember this well.
Up Special Move: PK Thunder
You guide the PK Thunder with the Control Stick...
...and hit yourself with it to launch!
Doing this helps you recover.
The angle you launch at depends upon the position at which the PK Thunder hits you. This launch also makes for a rather powerful attack, so I think it’s fine to even try it unexpectedly.
Down Special Move: PSI Magnet
This move absorbs the energy of projectile and other attacks and uses it to recover Lucas’s damage. It has a wide range of effectiveness, so give it a try when you get the chance.
If an enemy uses a projectile, that’s your chance.
