Mobius: 25 Years Later (Unaltered)
It is unknown for sure, but it seemed that the Chaotix had disbanded by this time, as Espio was Knuckles's secretary, and Vector and Knuckles had families. However, this would change as the timeline was altered. (StH: #131, #132)
Mobius: 25 Years Later (Altered)
In this timeline, the Chaotix were the brutal enforcers of King Shadow and were much larger to include trained Echidna soldiers led by Knuckles who carried out the king's orders. However, this was changed after the tyrannical king was overthrown by Knuckles's daughter after he launched a sting operation into action. (StH: #166, #167)
Five Years Later...
Five years after Shadow's defeat, the Chaotix were attempting peace talks with the Mazuri Seperatists, particularly with a character known as "Bill". In response to a warning against a major threat from Silver the Hedgehog, Queen Sally considered reassembling the Chaotix in the absence of the dismantled Knothole Freedom Fighters. (SU: #5, #6)
The Chaotix are a fighting force, facing enemies directly, rather than the guerrilla tactics the Freedom Fighters used years ago. However, they are willing to engage in peace talks with organizations that could possibly be a serious threat to the Kingdom of Acorn.
