Centium Celebration is the 12th episode overall of Elite ANT Force.
A family gathering in Centium City for all Elite ANT Force team members leads to Kaz and his cousin, Gabe, discovering Quimby and Davenport family secrets that might just blow the minds of Fletcher, Oliver, Bree, Chase, Daniel, and Leo.
- As of this episode, everyone in Fletcher and Oliver's family knows about superheroes, but Kaz's family still retains Kyle's beliefs of Kaz having bionics.
- Davenport reveals that his great-great grandfather hated Oliver's great-great-great grandfather.
- This is a crossover with Good Luck Charlie.
- Ariel Winter was supposed to portray one of Oliver and Fletcher's cousins, but couldn't do to a busy schedule. She later came to the show in a different role, as Chase's girlfriend. She was William Brent's costar from Opposite Day.
- Chyna mentions Berry Figgenbottom, a boy who looked a great deal like Chase, upon seeing Kaz with Gabe. Chase responds that Berry could have been his future son- "If superheroes are real, anything's possible." This is later proved as true because Berry Figgenbottom is the name of the first son had by Chase and his ex-wife, Tina Figgenbottom. Additionally, Berry had access to a time machine and has called Chyna hot.
- This is the final episode set in 2017.
- At the end of this episode, Oliver reveals to Skylar that he used to date Olive.
- Adam has gone missing, and no one knows where he is. It seems Bree and Chase have forgotten him entirely, to the shock of Leo, Daniel, Kaz, and Oliver.
- Stefanie Scott makes another appearance, as does Aedin Mincks.
- Charlie and Toby from Good Luck Charlie are the only Duncan family members to have no lines and appear only as cameos. This was because their actors had quit acting by this point, so they were recast.
