Rolf

Rolf is the porter in the apartment complex Leonard Snart and Mick Rory have been placed in. As such, he is present to quite a lot of the group's shenanigans.

Trivia

 * Mick Rory seems to believe that every apartment complex has a porter, refering to them as just 'Rolf'.
 * His wife's name (Martha) is a reference to both Bruce Wayne's and Clark Kent's mothers both being named Martha.
 * He has a brown belt in Judo.
 * He likes to pass on information about the inhabitants of his building to his family.
 * Rolf has not been given any information about Snart and Mick beyond them being thieves, as it appears. Because of this, he didn't know not to give Mick a lighter when he asked for one.
 * He and his family have referred to Mick as "Nose" and Snart as "Eyelashes" for quite some time.
