Episode 25

"Boss Fight ~The Final Light~" is the 25th episode of the Mob Psycho 100 anime adaptation, and 13th, as well as the final episode of the second season.

Synopsis
The Cultural Tower floats above Seasoning City. The final battle between Mob and Suzuki was about to begin. Mob is almost overwhelmed by the fact that he's able to completely release his powers, but then, he sees his younger brother, Ritsu. Mob regains his composure and he faces off with Suzuki, but Suzuki's power is too great. Mob finally gives up on trying to talk things out and puts everything he has into this battle. Who will be the victor?

Plot
Through a gradual shift of different 100% emotions, Mob forces Toichiro to go 100% with his own power, which in turn makes him lose control over it, causing Toichiro to turn into a living bomb capable of wiping out the whole city. Mob, showing his kindness to Toichiro, redirects the power into his body, leading to a seemingly smaller explosion that keeps the city safe. In the aftermath, Toichiro admits his mistake and allows himself to be taken into custody, after apologising to Sho. On television, it is shown that the apparent huge explosion actually caused the sudden growth of the broccoli seed that Mob kept in his shirt pocket, forming the Divine Tree.
