There's always been more to Transformers robots - but now fans can see these larger-than-life characters unite with other characters, teams and individuals who share this special trait thanks to the Transformers Collaborative. This Transformers-X-Men mix is truly revolutionary. The iconic X-Jet from the X-Men animated series is now a Transformers robot called Ultimate X-Spanse. Unlike the Sentinels, this robot is the ultimate ally of the mutants.
