Petaforth (ペタフォース Petafōsu) is an upgrade of Peterchy in Mega Man 7. They occupy particular platforms and walk back and forth across them.
The Peterchy have a brief cameo in Issue 43, where some were sucked into a reversed dynamo, causing them to detonate and presumably damage the dynamo while Magnet Man is monologuing to himself. They also appear in Sonic: Worlds Unite Battles as one of the robots from the first three games in the Sky Patrol's training room.
