Continuing to explain his experiment, the Player notices Dee Dee creeping around in the background as well as hearing her tinker with various things while she giggles. Before continuing, the Player designs their Avatar and creates an In-Game Name for their character. This Dexter looks much older than his Television counterpart, as do many of the FusionFall characters. The beginning of the original FusionFall starts with Dexter, from Dexter's Laboratory, thanking the Player for participating in his Time Traveling Experiment. The previous game's Future included (excluding the Tutorial) Five Accessible Infected Zones, Three Fusion Lairs, and Eight Areas in the Future. The Transportation Systems (excluding walking and Vehicles) included: KND S.C.A.M.P.E.R.s and Monkey Skyway Agents. The Future only had two Main Hub Areas, which were located in Sector V and Peach Creek Commons. In the previous FusionFall game, the Past was filled with diverse opportunities and the Future limited the Player to allow them to adjust to the game. Various characters in the game seem to beginning to lose hope, as more and more CN Characters are lost to the War, but they are still trying as hard as possible to win the war.

What once was a diverse and colorful sky that resembled a normal Earth sky, is now a green tinted atmosphere that only shows how much closer Fuse is to winning the war. The only areas left now are islands in the Fusion Matter Sea, connected to each other with wooden bridges.

All of the other areas found in the Past have been swallowed/flooded by the sea, which is now entirely Fusion Matter. What was once a large world for the Player to explore is now thinned down to a small section of the Suburbs. Planet Fusion (sometimes referred to as Fuse Planet), is much closer to the Earth in this time period than it is in The Past. The Future is a dark, apocalyptic time period where the War against Fuse has been unsuccessful so far resulting in Fuse nearly conquering the Cartoon Network Universe. 5 NPC's: Non-Playable Characters (Original FusionFall).
