All powerup supers allow for another post Frank super picture.
Multiple assists are useful.
Theoretically (need to test this) there are a lot of other situations in which Frank should be able to abuse something like the Frequent Flier Miles glitch (see Firebrand). It seems that a capture state into a super and a DHC before the super hits sends the opponent into a flying state. Good examples of these are:
Hawkeye:
Hunter
Firebrand:
Bon Voyage
Deadpool:
Ninja Gift (Bolo)
Spencer:
Bionic Maneuvers
Trish:
Peekaboo
Magneto:
Hyper Grab
Dante:
Grapple
Haggar:
Hoodlum Launcher L (must jump cancel into super)
Storm:
Elemental Rage Hyper (First Hit)
Spiderman:
Maximum Spider Hyper
These moves lead into that special state and open up some new and interesting options for characters that may not have had the ability or much utility to level Frank before such as Storm, Deadpool and Hawkeye. Storm, Spider-Man, and Spencer being able to DHC straight out of their Hypers is also extremely useful. Trish’s Peekaboo, Magneto’s Hyper Grab, and Haggar’s Hoodlum Launcher L can really open up some possibilities late in combos with fast fingers. This can also be used as a possible way to increase damage with someone who works well with low hitstun deterioration (MODOK?)
