- "If thou dost wish to challenge the Odinson, thou will face the divine power of mighty MJOLNIR!"
- — Part of Thor's Mighty Speech.
Mjolnir is the hammer that was previously owned by the God of Thunder, otherwise known as Thor Odinson. He is known to be one of Alisa Bosconovitch's friends.
His powers involve slamming himself onto the girls when they sleep, forcing them to awaken as Mjolnir has electricity powers that go up to three-hundred volts, but according to Alisa, three-hundred volts is enough voltage to kill someone, and therefore Mjolnir vowed to never slam himself onto anybody. Evil-Man revealed in Mjolnir's Alisa's Adventures in Rockoland premiere episode that his Electro Cannon has only two volts.
Mjolnir has the following voice actors:
- Bob Carter, Balrog's Street Fighter IV voice actor, in Alisa's Adventures in Rockoland
- Joe DiMucci, Edmond Honda's Street Fighter IV voice actor, in Barney and the Rocko Squad
- Kyle Herbert, Kazuya Mishima's Rocko franchise voice actor, in Xianghua in Rockoland
