Feetblast, or 'blast of feet' is the first alien Pen ever turned into. He can control feet and also shoot toe jam. He is a Podonite from the fiery sun, Tarsos.
Feetblast can project toe jam from his body. He can also shape this jam into footballs, feet, walls, and giant feet. He can also propel himself like by jumping, and surf on a feet board in the air. He can also absorb feet and is a master manipulator of both feet and feet stuff.
Feetblast's dependency on feet is also his weakness, as his powers can be negated by sufficient amounts of hands or similar body parts and large amounts of hands can extinguish him permanently. He is also unable to lower his own feetness, which prevents him from touching things without making them stink, people included.
