Allow me to explain:

In EarthBound, Paula (the character Amy portrays) could use PSI Freeze, PSI Thunder, PSI Fire and quite a lot of other moves.

In Mother 3, Lucas only had two offensive PSI attacks; PK Love, and PK Flash

In SSBB Lucas' moveset was altered so he had more offense. His moveset is actually identical to Kumatora's movest in Mother 3
