Zixx
Zixx (full title is "Zixx: Level One" for season one, "Zixx: Level Two" for season two, and "Zixx: Level Three" for season three) is a Canadian television series that aired on YTV. This series was developed by Savi Media and The Nightingale Company & Mainframe Studios with YTV Original Productions. The series was created by Jeff Hirschfield. The show consists of a mixture of live action real world sequences interspersed with computer-generated scenes set inside a virtual realm. In Zixx Level One, Elliott Digital used game engine LithTech to create the animation, the first time this was done for  a television show. For Zixx: Level Two, the production had to move to British Columbia when Thunderbird Films Inc. joined the team. Mainframe Entertainment came on board to do the animation and IDT Entertainment, the company that owns Mainframe, took over distribution of the show. It is the first ever Mainframe series to combine live action with computer animation. The crew would stay for season three. Plot. Zixx is an Intergalactic Network (simplified as the Network) agent who has crash landed onto Earth with her partner Flanngo. As luck would have it, Earth also happens to be a hotbed of  activity for the evil Onccalon and the Hargokk Empire. Zixx has no intention of letting him win, so she and Flanngo need to find a way to access the Network and make sure they can get to the next level of the Keep before Onccalon's henchmen do. Level 1. Zixx and Flanngo need to find a way into the Keep, a trans-dimensional antimatter field (a cyber dimension resembling a video game), the last legacy of the ancient Gaanth race, the leaders of the Network (reminiscent of "Tron"). The difference is that death is permanent if they die in  the keep. Reluctantly accepting the help of earthlings, Adam and Griff, the four need to move fast and finish level one of the Keep, to do so they will need to recover the six fragments of a crystal that are scattered throughout the level. When the crystal is whole and combined with the crystal base, it shows the map to the three neuropods buried deep within the level that, when solved, show the path to the next level. They must accomplish all of this before Onccalon's henchman Deeth does. Level 2. Having made it to the shifting labyrinth of  level 2, Zixx and Flanngo have gotten a nice inventory upgrade, but seem to have lost their pals Adam and Griff. Finding their new Earth location outside of the Keep to be a quiet rural town called Glen River, they find themselves forming a new team composed of their new friends Riley, Meghan, and Dwayne. Zixx needs to keep one step ahead of her foes. Unlike the previous level, level 2 changes layout randomly making it difficult to find locations again. Zixx and her new team must find the key to the golden gate, the portal to the next level , but it is not as easy because the gate also shifts around. They will need to hurry and beat various new agents of the Hargokk Empire, as well as finding out that Onccalon is still alive and regenerating now they need the help of Adam and Griff. Level 3. Zixx is thrilled when her team enters Level Three intact. The challenges of Level Three turn out to be far greater than the previous levels, requiring puzzle solving to gain upgrades and somewhere on this level in the Keep, Onccalon is growing ever stronger and is about to be resurrected. Only  the most powerful weapon of all time can defeat Onccalon, and so the race is on to find the Sword of Gaanth, which is split into a hilt, a blade and six Vortrian gems. If they fail, then the last remaining Gaanth who resides within the sword will destroy the entire universe before Onccalon can rule it. In the end, Onccalon is destroyed by Zixx using the Gaanth, and Zixx, Flanngo and Tarphex go back to their home planet.
