The only season finale of the series to air as a 1-hour event. After the original airing, this extended episode (as other extended episodes before it) was divided into two episodes, parts one and two.
This 1 hour Event has a few similarities to the 1 hour Event from Season 2, "Bionic Showdown":
-Both involve capturing someone to lure the Lab Rats to them.
-Both involve the captives being trapped with a walled area that blocks the Signals from their Bionic Chips.
-Both involve Marcus showing the Captives being captured to the Lab Rats (this time Marcus is wearing a Cybermask to make himself look like Daniel).
-Both involve Marcus knocking characters out into being unconscious with them regaining conscious in their prison (this time being Adam, Bree, Chase and Leo).
-Both involve Leo saving the day in a way.
-Both involve Marcus having a Terrible Defeat.
