Thunderforce Resurrection

Clearly Thunderforce's most bizarre capability was Serial Immortality, which in his case caused him to automatically resurrect 27 days after his corporial body was killed.  When asked by another character about this, Shawn replied "My body is now composed of energy.  The death of my physical form is now more like a system crash.  The energy scatters, but doesn't dissipate, so it eventually coalesces anew."

This account has been questioned a number of times-- Thunderforce had a penchant for inventing colorful explanations to technical problems he did not want to discuss.  If it is true, then Thunderforce's Resurrection power might be vulnerable to energy absorption or limited in locations with strong electromagnetic disturbances.
