"New Thunderbolts"
After the failed "Fightbolts" Retool, the comic was relaunched in 2005 with a new #1 as "The New Thunderbolts". The series brought back several longtime series favorites like Atlas, MACH-IV and Songbird and allied them with a brand-new team. The series would last for 18 issues before returning to its original numbering for the landmark 100th issue, with subsequent issues numbered accordingly.

After the fall of the Soviet Union and the coming relations between China and the US, Chen Lu disappeared for several years only to return again, seeking a new purpose in life.
