Clever Nintendo with their clever trailers…! ^_^

They only have the same Name!!!
The effects are different
They have different Aerial Attacks
They have different Smash
More differences than similarities

they are the same
they’re annoying runts with psychic powers from the same game Ness has PK Fire Thunder and PsI Magnet
Lucas has PK Fire, Thunder and Psi Magnet
they’re the same height a weight and jump the same
they even share the same Final Smash
they’re attack animations are the same too

and saying they do different things doesn’t make them brand new moves

AHA!
the word is SIMILAR
Clones would have the SAME!!!
And They “basically” don’t have the same specials the only thing is the name

You haven’t won this
you can’t deny they basically have the same specials
and similar smashes

well, lets just say most of my friends dont realize that you can win without legendaries and the move fly.
(thats why I always beat them XD)
you do have a point though, but I just choose insomnia out of process of elimination

It is not 😛
That source just says Lucas is a Semi clone

Still a clone nonetheless
